    New varieties challenge yield thresholds and offer valuable on-farm agronomic characters


    At Cereals 2015, Limagrain will introduce three exciting new varieties for the winter OSR, wheat and bean markets.

    Nikita is a conventional oilseed rape candidate variety, with a gross output of 110% on the east –west HGCA Recommended List putting it in joint highest position, 10% above DK Cabernet and 12% over Excalibur. Whilst in the north it achieves 114% gross output, making it the second best performing variety.

    Nikita offers a glimmer of hope in the battle against Light Leaf Spot as it has a LLS rating of 8, which would make it the highest on the HGCA Recommended List. Dr Vasilis Gegas, senior oilseed rape breeder with Limagrain UK, notes that in years when LLS pressure is high and widely spread, such as in 2015, resistance ratings may come under pressure and therefore there’s a distinct advantage in starting with the highest rating possible.

    “Additionally it has the short stiff stems that growers prefer for ease of harvest, and very good lodging resistance. Nikita is also medium to flower and mature.”

    Britannia which was fully recommended in 2014,is a high yielding Group 3 biscuit wheat producing yields comparable to the feed wheats. Limagrain’s Ron Granger notes that Britannia, rated 104 across the UK and two points higher than stable-mate Zulu, is the highest yielding variety in the biscuit wheat category. “It sets a bench mark yield that elevates it above the rest of the pack.”

    Similar in height to Invicta and JB Diego, the variety is moderately stiff strawed, and is similar in ripening maturity to Scout. Britannia also offers a very good disease resistance profile, with an 8 for yellow rust and a 6 for septoria tritici combined with good grain quality attributes.

    Added to the PGRO Recommended List in 2014 as the highest yielding winter bean, Tundra is an exciting new variety with a pale skinned and a pale hilum colour, potentially suitable for the premium export market for human consumption.

    Offering a 9% yield advantage over long-time market leader Wizard at 106%, Tundra has good agronomic attributes, being a moderately short strawed variety with good standing ability. Tundra is also relatively early to mature.

    Breeders from across the arable portfolio and Limagrain representatives will be on hand to provide information on all Limagrain varieties, such as high yielding wheats; Evolution and Zulu and oilseed rape, Amalie.

    Crusoe - three years on

    At its launch back in 2012, Crusoe set the standard for a new kind of milling wheat that offered very high yields, exceptional quality and agronomic characteristics that meant it could be grown across a range of on farm situations and perform consistently even in high incidences of disease pressures.


    Since its launch into official trials, the variety has been tested in very different seasons each offering its own set of challenges from the very dry springs in 2010/11 to the extreme disease pressure seasons of 2012 and 2014. How has the variety withstood these challenges and has it fulfilled its promise of being able to deliver both on farm and to market requirements?


    When developing a new milling wheat, the variety has to be able to deliver the basics of good protein content, Hagberg and specific weight says Ian Foot, quality wheat manager with breeders Limagrain UK. But there’s also the quality of the flour, its functionality and baking performance and colour – and for it to make a Group1, it needs to deliver all of this consistently.


    “Yield is the primary trait we breed for to get onto the HGCA recommended list - it has to perform, but alongside this, agronomic characteristics such as good disease resistance and straw stiffness are important attributes for consideration.”


    Crusoe is a cross between long time market favourite Cordiale and a Limagrain variety Gulliver which is less well known, but gives Crusoe its distinctive iridescent green colour and the genetic disposition for a high protein content.”

    “Quality is a genetic trait so there is an element of predictability in building it into a variety, but it’s all about the type of protein and its consistency. The right type of protein is difficult to define but it manifests itself in the bake for bread flour and this all comes down to how the variety processes nitrogen. In a good milling variety, nitrogen is used for building protein as well as feeding yield.”


    Crusoe was identified by Warburtons to stand out in baking tests when it was first trialled in 2007; it has the whitest flour with a high protein content and good functionality. It produces relatively strong gluten, like Gallant and has shown itself to deliver this consistently.

    Stuart Jones, technical controller for Warburtons notes how Crusoe quickly established itself as an integral part of the Warburton’s wheat growing programme. “Consistency of flour performance is essential when baking at Warburton’s. We expect a lot from our raw materials especially the flour to ensure every product produced meets the standards our consumers demand. We need to know that any variety we take on has an ability to deliver against the specification year after year and Crusoe has exhibited all the Warburton’s specific traits expected during bake tests.”


    “Protein quantity is what’s measured but its protein quality that matters. Crusoe puts a tick in both boxes. Year on year Crusoe has continued to deliver and Crusoe remains within the Warburton’s wheat selection plans going forward.”


    Ron Granger, arable technical manager with Limagrain backs up these findings and points out that this consistency of quality offering is what sets Crusoe apart from the other Group 1 wheats.


    “In all of the trials we have conducted either in house or with industry partners, the message is the same – year on year, irrespective of region, rotation slot or soil type –Crusoe consistently delivers yield and quality.”

    HGCA RL data- Seasonal Protein Content


    There’s also no doubt the variety yields, adds Mr Granger. Data from 2014 Agrii COGS trials show Crusoe’s top yielding performance across the UK; with a more typical farm fungicide programme. The trials were carried out on both heavy and light-land sites.

    “What we see is a robustness of performance across soils types and regions. For example in Essex the crop yielded 13.6t/ha which was well above Skyfall (13.2t/ha) and KWS Trinity (13.3t/ha). Results from the other side of country in south Wales, show a similar picture with Crusoe yielding 12.9t/ha, 0.8t/ha over KWS Trinity and 0.2t/ha over Skyfall. This trend continued across the sites in Wiltshire and Yorkshire.”

    “Final mean figures show Crusoe produced a top yield across the sites of 12.6t/ha, higher than both Skyfall (12.5t/ha) and KWS Trinity (12.1t/ha).”


    These results were replicated in our trials in harvest 2014 adds Lee Bennett of Openfield. “Crusoe was the stand out variety from harvest 2014 in my opinion. It readily yielded about 0.5t/ha more yield than was anticipated by comparison to its recent historic performance, and fortuitously in a low protein year, it was commonly 0.5% higher in protein than other Group 1 varieties. “


    “With no issues around any of its physical qualities, Crusoe has become universally accepted by its growers and by the millers as being a solid Group 1 and it will have no trouble finding a home. “

    More Profitable Milk!

    More Profitable Meat!

    The brand new range of LG Animal Nutrition grass mixtures are the first grass mixtures to be formulated with the animals complete dietary requirements in mind. Not just to increase intakes, but also maximise the nutritional content of every kilo fed.

    Maximum milk or meat production, together with minimum production cost is the common aim of all farmers with a profitable business enterprise. Animal feed, whether in the form of bought in concentrates or home grown forage, makes up a significant proportion of production costs and the nutritional quality of this feed plays a critical role in ensuring maximum production is achieved.

    Our unique range of LG Animal Nutrition grass mixtures are designed to be superior in their nutritional quality, leading to improved production and ultimately more profit.

    Scientifically proven

    Trials conducted at the Schothorst research institute in the Netherlands in 2013 clearly showed the benefits of reseeding with LG Animal Nutrition grass mixtures. Cows fed with a high quality LG Animal Nutrition grass mixture produced 1.4 l/cow/day more milk than the control mixture.

    Late drilling slot still available for high yielding Evolution

    There is still a good opportunity for growers looking to drill wheat in the later drilling slot however it is important to select the right variety for this slot, says Ron Granger, arable technical manager for breeders Limagrain UK.


    “It is important to recognise the specific characteristics of wheats suited to this later dilled slot– they need to be strong tillering, with a faster ear development and growth habit in the spring. As breeders we have various seed growers who drill their wheats after sugar beet or potatoes and we have been able to judge which varieties have done well in this slot, over a range of different seasons and challenges.”


    “We have seen some very good results from Evolution drilled in this later slot,” he adds.


    “This high yielding Group 4 has proven itself to be a very flexible variety in that it performs well in many situations giving growers a variety that has shown consistency over years, regions, rotational position, soil type and drilling date –without compromising on its top yields.”


    The recommendation is that Evolution fits the mid-late drilling slot with a latest safe sowing date of mid-February. Evolution drilled in late November and January trials has given better yields than alternative / spring wheat varieties, a preferred option by many growers, notes Mr Granger.


    “However beyond this and once you get into mid-February sowing dates, spring wheats would be the preferred option.”


    “In addition, where black-grass is a challenge, trials results have shown that if Evolution is later drilled, the variety would appear to compete with the weed and still goes on to produce yields superior to many other leading commercial wheat varieties.”





    “Soils are still relatively warm, so establishment at the moment should be good which is important. However seed rates need to be adjusted accordingly depending on seed bed conditions, date of drilling and weather conditions at the time – and often this requires rates to be raised slightly- but growers will know what works for individual fields.”


    He points out that later drilled varieties often have the advantage of requiring lower inputs, and may not for example, require an earlier autumn herbicide. Varieties such as Evolution have robust disease resistances that help to combat and withstand early spring disease challenges.


    [PANEL] 2015 yield results

    Evolution has proven itself to be a high yielding variety that can perform consistently across seasons, regions and rotations and there have been some fantastic yields this season.

    Lincs grower David Hoyles, recorded his highest yields ever, with a massive 15.47t/ha from a single field of Evolution and an impressive average yield of 15t/ha from across three fields.


    [Summary box]


    · Evolution

    · Nabim Hard Group 4

    · High treated and un-treated yield

    · Recommended for mid-late drilling slot

    · Very good disease resistance profile

    · Good resistance to lodging

    · Good second wheat performance

    Recommendations see value placed on agronomic and marketing attributes


    The announcement of this year’s AHDB Recommended List sees a range of varieties securing full recommendation from breeders Limagrain UK

    that offer new thresholds for a range of agronomic and marketing qualities.


    Spring barley

    Continuing the established and successful line of dual purpose, non-GN spring barley varieties, Origin and Ovation have received full recommendation.

    Origin is a high yielding variety with potential for brewing and malt distilling. Offering 8% yield benefit over Concerto, yielding 104% over control, the variety has performed well in the north and east, suiting established spring barley growing areas.

    Origin is moderately short strawed with good lodging resistance offering good disease ratings with a (9) for yellow rust and a 6 for Rhyncosporium. Its high Hot water Extract properties make it one of the best on the Recommended List (RL).


    Ovation is the highest yielding feed barley on the RL, yielding 11% over Concerto at 107% over control, which includes good yields also in the west of the country. Its rating of 7 for brackling and Rhyncosporium underpins these high yields.

    “Although not suitable for UK malting requirements, the variety is in French CBMO trialling, and has had good results in both Czech and Danish trials, so could be suitable for export from more southern farms, ”says Les Daubney, arable marketing director with Limagrain.


    Oilseed rape

    The conventional variety Nikita, which has a Light Leaf Spot rating of 7, makes it one of the highest on the HGCA Recommended List. “Varieties with high LLS ratings show significantly better natural resistance compared to other varieties providing that bit of breathing space required to treat the crops, and should be selected as an important element in the fight against this very damaging and increasingly high threat disease,” says Dr Vasilis Gegas, senior oilseed rape breeder with Limagrain,



    “The last two years have seen the spread of the disease, which has been accelerated by the warmer winter experienced in 2013 and 2014, allowing earlier infection and more rapid recycling of the disease- and this winter is not looking very different so far.”

    He notes that in years when LLS pressure is high, resistance ratings may come under pressure and therefore there’s a distinct advantage in starting with the highest rating possible.

    Nikita not only offers a significant step forward for integrated disease management but also delivers solid seed and oil yield, being one of the highest on the RL for this category, at 45.6%



    “With its high LLS resistance, short and stiff stem and earliness to maturity, Nikita fits well with the requirements of the northern region and has been fully recommended for the North. Unexpectedly however, it has not been accepted onto the East- West list despite its obvious favourable characteristics. According to the AHDB, this decision has come about solely as a result of Nikita’s lower, though above the minimum standards, stem canker rating, but we strongly believe that this should not deter growers from the variety as it performed very well across the country this harvest, and is well supported by the seed industry and growers alike. “



    Amalie is the only commercially available oilseed rape variety with resistance to TuYV on the market, and its recommendation this year confirms the importance of this characteristic.

    Amalie is a conventional OSR variety that offers a gross output similar to the widely grown variety, DK Cabernet. In situations, where aphids are difficult to control and infection levels of TuYV high, Amalie will yield as much as susceptible varieties.

    Agronomically the variety offers sound agronomics and robust disease resistance ratings, with a 6 for LLS and 5 for phoma, with an 8 for standing power and stem stiffness, so with no obvious weaknesses there is a serious case for growers to consider making it part of their OSR cropping next season.


    Pulses

    Kingfisher, a large blue pea has added to the RL list for 2016. “Its slightly lower yield at 98% is more than compensated for as this variety offers superb colour, as good as Daytona, making it very suitable for the micronizing and other premium markets,” says Milika Buurman, senior pulse breeder with Limagrain.



    “Kingfisher although slightly taller, has one of the highest standing ability ratings of 7 on the RL, it also has a rating of 6 for downy mildew, so should find favour on farm easily.”

    Use the correct seed rate for spring barley varieties to ensure optimum establishment


    The standard seed rate of 350 seeds/m² appears to be the ideal seed rate for many of the spring barley varieties when good seedbeds and growing conditions are conducive to quick plant emergence, states Ron Granger, Limagrain UK’s arable technical manager.

    This season is no different, as growers should be patient and delay drilling, until good seed beds with warming soil temperatures ensure quick plant establishment – spring growing crops do not like growth checks.



    ”We have carried out trials, looking at variety interaction with seed rate for two consecutive seasons in both Scotland and Norfolk. These two seasons were very different with regards to establishment and disease pressure –however despite this a rate of 350 seeds/m² would still appear to be correct.”

    “Although we saw a slight increase in yield in the 2015 data sets, especially for the newer varieties with an increased seed rate, in general over two years the 350 seeds/m² rate would appear to be the most cost-effective.”



    However he points out that seed rates for spring barley, as for many cereal crops is not an exact science and will need adjusting depending on drilling date, tillering capacity, soil conditions, weather forecast, pest activity and most importantly growers knowledge from previous experience.



    Specific weight

    “Specific weight however would not appear to be greatly influenced by differing seed rates, but in general the standard 350 seeds/m² in the 2014 and 2015 season, produced the best specific weight for the majority of the varieties in the trial.”



    “In general the drive for higher yield has driven varieties towards a later maturity and it is also quite evident that these varieties would also appear to have lower specific weight recordings as compared with past older varieties – but Sienna bucks the trend -and has the best specific weight on the AHDB Recommended List.”

    “It’s necessary to keep testing these new high yielding lines to ensure that historic agronomic inputs are still relevant in today’s climate, especially when we know that many of the new spring barley varieties have significantly increased yield potential over the last six years.

    Suspicions that the aggressive Warrior 3 rust race could be a threat this season have been raised by breeders Limagrain UK; growers are warned to be extra vigilant in checking their wheat crops.



    The Warrior 3 race of yellow rust was identified at several sites across the UK by Limagrain breeders at the end of the 2015 growing season when yellow rust suddenly exploded on a number of varieties, despite their high resistance ratings, levels of infection very quickly reached significant levels.



    Cereal pathologist with Limagrain, Paul Fenwick explains the findings: “We had some ‘very different and unusual yellow rust sightings’ last year in Scotland, Lincolnshire and Suffolk; varieties that were previously clean and resistant to known rust races were suddenly covered in rust. For example, Invicta had over 50% of its leaf area infected, despite its AHDB rating of 8.”



    “From our geographically extensive trials, we have made our own isolates and tested them on seedlings and found all of them to be consistent with coming from the Warrior 3 group, as recently defined by the UK Cereal Pathogen Virulence Survey (UKCPVS).”



    “This was not what we expected, as if we reference the findings presented at the UKCPVS stake-holders meeting in March, Warrior 3 pathotypes were found to be much less frequent than Warrior 4-6 type in 2015.”



    “However, if our findings are correct, and Warrior 3 has increased its frequency in the mix of yellow rust types out there now, it’s possible that we could be seeing some real surprises in varietal resistances in 2016, and most probably before the latter part of the season”, he says.



    It is believed that all the Warrior group of races originated in the Himalayan region, and the fact these are from a sexual population goes some way to explaining their variability and atypical characteristics compared to the clonal, European population that we’ve been used to for so long. The Warrior groups of yellow rust are now totally dominant within the UK population and also across Europe.



    “Limagrain is routinely running seedling tests - as it is important for us to characterise both seedling and adult plant resistance to the various strains of yellow rust. We’ve recently found that seedlings are generally more susceptible to new races compared to isolates from the old population – some of the new ones appears to be particularly aggressive in our seedling tests, and could be one explanation for why we are seeing such high levels of yellow rust in fields currently,” adds Mr Fenwick.



    “We know that the Kranich race has been detected for the first time in the UK (a single occurrence in 2014), but much like the Warrior 3 race, the actual risk posed by it is still unknown at this stage. It might be that we need to be equally concerned about this race, as the Warrior 3 races.”



    “As breeders, we are constantly working, with the help of genetic markers, to gain a better understanding of the genetics underlying the rust resistance in our varieties. Whilst many important resistance genes have become less effective against the Warrior races, we are also seeing that some, previously overcome genes, are now working again.”



    “The reality is that we don’t know where it will be seen again or how the Warrior 3 race will behave, but we do know that it appears to be more aggressive than the Warrior 4 race, so the message for growers is that they need to be extremely vigilant in checking their crops and don’t take any varietal resistance ratings for granted,” adds Ron Granger, technical manager with Limagrain.



    Manufacturers BASF say that if yellow rust symptoms appear in crops, growers should take a zero tolerance approach. “There is a lot of uncertainty about which varieties are likely to develop rust and we are seeing active disease in a range of varieties which would not normally be considered high risk,” says agronomy manager Louis Wells.



    “There is still a versatile and effective toolbox available so growers should feel confident about control; epoxiconazole is the best rust triazole, pyraclostrobin the best strob. Where using an SDHI ensure you choose an SDHI which is partnered with epoxiconazole – in practice this means Adexar.”



    “Chlorothalonil (CTL) should also be included to boost Septoria control and as an anti-resistance strategy. In our trials, the potential for antagonism from adding CTL can be even greater when treating rust than septoria, but we have never seen an issue of this with Adexar,” he says.

    Second wheat performance – how to maximise farm income

    upload_2016-5-9_8-50-49.png

    Good second wheat performance could depend on choice of first wheat. Work from breeders Limagrain UK would suggest that first wheat variety choice could have serious implications for the following second wheat crop.



    Known varieties that under-perform in the second wheat situation would appear to have a negative effect on the following wheat crop, if grown in the first wheat situation, says Ron Granger, arable technical manager.



    “This would suggest that these poor second wheat varieties allow take-all inoculum to build up in the soil, which can lead to devastating yield loss in the second wheat situation, especially if a poor second wheat variety is selected.”



    “Many wheats marked as ’good’ second wheats on the AHDB Cereals and Oilseeds Recommended List may not actually be the most suitable for this position due to a lack of good phenotypic data, as this second wheat root disease is complex and not straight forward.”



    “Take-all infection in the field is very sporadic and consistent evaluation of the data is difficult, but never the less, we do have seasons showing high levels of take-all and it is important to acknowledge the diverse differences in varieties.”



    Mr Granger believes that from a take-all management point of view, first and second wheats need to be considered as pairs. Trials work carried out by Limagrain in 2008/9, which were both

    seasons with high take-all incidences, show the performance of a second wheat can differ by as much as 4.2t/ha if the wrong first wheat precedes – a significant impact on farm income!



    While some growers may select a variety with high eyespot resistance for a second wheat slot, he wonders if these cultivars would be more useful in the first wheat position, as interestingly the trials work carried out in 2008/9 suggested that a variety with Pch1 (Rendezvous) eyespot resistance grown in the first wheat situation had lower take-all build up, with the knock on effect of higher yields achieved in the second year for all varieties tested.



    However, when choosing a variety for second wheat, take-all isn’t the only pathogen that growers should bear in mind, he continues.



    “Eyespot, both sharp and common, and fusarium foot rot all need to be borne in mind.”



    Mr Granger believes that with new technologies such as the CT scanner technology at the University of Nottingham and the work being done by several of the institutes on take-all, will allow us to get a better handle on this complex disease.



    “New and evolving technologies will allow researchers and breeders to analyse a variety’s root mass in a non-destructive manner. This means that breeders may be able to select for more robust varieties against take-all, by choosing varieties with greater root-mass development in conjunction with varieties that inhibit lower levels of take-all build up.”

    A scientific paper based on work at Rothamsted in 2010 confirmed these findings (McMillan, Hammond-Kosack; Gutteridge 2010). The project produced the first evidence of relatively consistent differences between wheat cultivars in their interactions with the take-all fungus, which could give an indication of those cultivars that could be grown as a first wheat crop, in order to reduce the risk of damaging take-all in a second wheat crop. This phenomenon has been named the take-all inoculum build-up (TAB) trait.



    “We still have a lot to learn about the second wheat scenario but slowly and scientifically we are starting to unravel the complexities associated with the take-all disease. Hopefully in the future we may be able to achieve yields comparable as a first wheat for the second wheat situation, as this would certainly benefit growers for raising farm incomes across the UK, “says Mr Granger.



    [PANEL]

    Evolution has performed very well in both the first and second wheat situations in both Limagrain internal and external independent trials, showing that the variety is robust for on farm performance.



    “Evolution would appear to be more robust in dealing with take-all as it would appear to perform better in a second wheat slot than a first wheat. As a first wheat it yields 104% on the AHDB RL 2016/17, but move it into a second wheat slot and its performance jumps 2%”



    Bred by Danish breeder Sejet, the combination of the political climate and tight regulations around crop inputs in Denmark and the tendency for early generation selection of varieties in a second wheat situation would tend to produce wheats with greater root mass to improve nutrient-use efficiency. Modern technologies will allow scientists to study this claim more closely so we should have more data in the future.



    Britannia, also from the Limagrain portfolio is also a variety that performs very well in the second wheat situation, confirmed by both the AHDB RL and independent data sets. “This may be attributed to its parent Cassius which was also a very good second wheat, with proven performance on farm.”



    “In an early drilling scenario or if eyespot is a known concern, a variety such as Revelation with very good eyespot resistance based around the Pch 1 Rendezvous resistance should be considered.”



    These varieties offer growers very high yield potential for either the hard or soft markets, in either the first or second wheat situation as well as offering a combination of good agronomics

    and disease resistance, important attributes for ensuring consistency for on-farm performance, he says.



    Wet and mild conditions over winter and into the spring would indicate that take-all could be a problem in crops this season, particularly if we see a wet summer. In similar conditions in 2009, the typical signs of take-all infection which are stunted growth and premature plant senescence were clearly visible, and lead to yield losses of about 2t/ha.

    LIMAGRAIN TRIAL RESULTS SHOW VALUE OF COVER CROP MIXTURES

    UK field trials run by specialist seed company Limagrain UK have shown that benefits such as biomass production and nutrient capture, that reduces leaching, can easily cover establishment costs.

    Trials were carried out in 2015/16 on sites in Lincolnshire with varying land types. Two single varieties and four mixtures were each drilled directly into 0.4ha stubble plots using a Sky Easy drill or a Dale drills Eco drill. Samples were taken at regular intervals and measured for biomass and nutrient retention.

    “Oilseed Radish and mustard were compared with four Limagrain catch and cover crop mixtures all with specific attributes,” says Limagrain’s seed specialist John Spence.
    upload_2016-7-11_7-5-40.png

    These included Lift ‘N’ Fix – a rye and vetch mixture, Sprinter – a black oats and vetch mixture, Soil Improver with oats, oilseed radish, phacelia and mustard and Green Reward with rye, oat, oilseed radish, tillage radish, mustard, vetch and phacelia.

    upload_2016-7-11_7-4-45.png

    “The results showed that all the trial plots yielded between 2 and 2.5 tonnes of dry matter per hectare in a 12 week growing period, with Green Reward and Soil Improver producing more than 17t/ha of green organic material.”

    Based on N, P and K found in the green material after eight and 12 weeks, Limagrain has calculated a nutrient value for each mixture and showed that each can uplift significant quantities that would potentially have been lost if the land was left fallow. Lift ‘N’ Fix was the most successful – designed specifically to capture nitrogen - with more than 100kg of N being captured by the mixture, which, with the value of P and K based on current fertiliser prices (ammonium nitrate £210/t, triple superphosphate £275/t, muriate of potash £240/t) is worth £126.85 a hectare.

    “If we include the value of the nitrogen fixed by the vetch and £15 worth of sheep grazing we have a crop value for Lift ‘N’ Fix of £152/ha,” adds Mr Spence. “This outweighs the growing cost of Lift ‘N’ Fix of £138/ha.”

    Based on the trial results, Limagrain calculated the value for Soil Improver to be £156/hectare. “This mixture includes species with a variety of different rooting depths which help to relieve compaction through the soil profile,” says Mr Spence. “It is the mixture we recommend when soil compaction is the main priority.”

    Sprinter, a fast growing mixture that supresses weeds and is ideal where blackgrass control is a priority, had an estimated value of £148/ha. All three mixtures satisfy EFA criteria. Green Reward, the final mixture in the trials is a premium multi species mixture which covers all bases as a cover crop giving high biomass, soil conditioning and compaction alleviation as well as blackgrass control.

    “The cost of growing a single species cover crop may be covered by short term benefits like weed suppression and nutrient capture, but, for the same growing costs, farmers can reap additional benefits by using specially designed mixtures that fulfil specific roles.

    “A poorly designed or poorly established cover crop will bring few benefits above leaving the land fallow and may cause more problems than it solves. And simply selecting the cheapest crop that is EFA compliant could be a missed opportunity whereas mixtures designed to meet specific requirements will bring additional short term benefits and the longer term use of these well designed cover crops will also lead to improvements in soil health and organic matter.”

    Limagrain has detailed its mixtures along with growing advice and EFA regulations in its latest Soil Improvement publication available on line from: http://www.lgseeds.co.uk/expertise/download-soil-improvement-solutions-brochure/

    Plant Breeding post Brexit

    Limagrain UK is part of a fast growing, French farmer-owned international co-operative group, specialising in both agricultural and horticultural seeds, and in cereal products.

    So what does Brexit mean to a company like Limagrain, and what are the implications for UK growers?

    “It’s business as usual,” says Les Daubney, Limagrain marketing director for arable seeds. “Whilst Limagrain has its roots in the Auvergne plains in central France, its seeds activity is worldwide.”

    Limagrain is the fourth largest plant breeder and seeds marketing company in the world, and although the main part of the business is within Europe with 52% of total sales and 60% of the Limagrain workforce, 33% of sales and 20% of the workforce are in the America’s, 10% of sales and 7.5% of the workforce are in Africa and the middle east, and 5% of sales and 12.5% of the workforce are based in Asia, he says.

    “This shows the global approach and focus for the company; of which the UK business is a key part of, and this strategy will continue despite the uncertainties of a UK outside of the EU.”

    Limagrain has a dedicated UK breeding programme which consists of several key plant breeding centres based throughout the country, focused across a range of crop types, such as wheat

    breeding at Woolpit in Suffolk, barley and OSR breeding at the head offices in Rothwell, Lincolnshire and roots and pulse breeding at Docking in Norfolk.

    The breeding programme for each crop type is led by a senior plant breeder, who is backed up and supported by a local team including technical expertise, pathologists, breeding assistants and industry liaisons etc.

    Mr Daubney is keen to emphasise that the work of the breeders is very much part of the global strategic breeding programme of the company, where breeders from across the company share genetic material and processes, when relevant and appropriate to the individual and national requirements of the breeding programmes that they lead.

    “Plant breeding has many challenges to overcome in the next ten years, and we have to ensure that we adapt our programmes to meet these so that we continue to provide varieties that meet the needs of both growers and end markets in specific regions,” says Ed Flatman, senior wheat breeder with Limagrain UK.

    “Growers continue to expect quality and consistently performing varieties that will make a difference to their profits; this means that the varieties need to meet constantly changing market demands, which means breeding for local conditions but with access to genetic material, data and technology that may come from one of our international centres.”



    “Products need to be easy and economical to process as well as to source, and this is only achieved through the production of reliable and consistent varieties that have undergone extensive pre- commercial testing and evaluation between ourselves and key partners, and this requires local knowledge and understanding.”



    “Yield stability is key to the success of the programmes at Limagrain, and this means that we are aiming to produce varieties that easy to grow and deliver consistently year on year this is nothing new for us.”







    Candidates for 2016/2017 AHDB Recommended List

    It is this very process that is bringing forward several new and exciting wheat candidates for recommendation this coming autumn.



    LG Sundance and LG Motown are very high yielding soft feed winter wheats, with initial official testing suggesting that the varieties meet the specifications for both the distilling and soft uks export markets.
    thumbnail_LG Motown.jpg


    “We are particularly excited about LG Motown, which has consistently yielded 104.3 over control, and above JB Diego, and offers similar attributes to the popular variety Revelation, with some significant advantages. It’s earlier to mature than Revelation and JB Diego; an important attribute of consideration for growers of winter wheat in the northern regions of the UK,” says Ron Granger, arable technical manager for Limagrain.



    He adds that LG Motown has good resistance to the rusts; septoria and eyespot, as well as offering OWBM resistance.



    LG Sundance has an excellent disease resistance profile, with a very good ‘7’ rating for septoria tritici. Limagrain data suggests it is a higher tillering variety with a slower prostrate growth habit in the spring - attributes considered of importance for the earlier drilling slot.



    Stratosphere is a very high yielding soft feed winter wheat, bred by Danish breeders, Sejet.

    Stratosphere has a good disease resistance profile and carries resistance for OWBM, and trials to date suggests it also performs well as a second wheat.



    LG Cassidy is a very high yielding winter wheat, with initial official testing suggesting that the variety meets the specifications for the nabim Group 2 sector. LG Cassidy is a shorter strawed variety with good lodging resistance, a durable disease resistance and good physical grain characteristics.



    “LG Cassidy is similar to Einstein with respect to its lower tillering, erect habit and rapid spring development.”



    “Limited data suggests a low vernalisation requirement, similar to Panorama, which gives the additional benefit for later sowing after roots or where blackgrass is an issue. It has also shown good second wheat performance.”



    LG Bletchley is a Group 3 variety that offers potential for all the soft wheat markets; export, distilling and biscuit wheat. LG Bletchley is an early maturing variety with stiff straw, good disease resistance and OWBM combined with good grain quality, which makes it an interesting option for the North.



    “It’s a medium tillering variety with an erect habit and more rapid spring development, and it is under evaluation for its suitability across the whole sowing range, early to late.”

    The future is bright for the Limagrain wheat breeding programme



    Bringing high yielding wheat varieties to market that offer a range of attributes to reflect the differing agronomic and marketing requirements of farmers across the UK, has always been a focus of the Limagrain UK wheat breeding programme.

    This has never been more evident than in this year’s winter wheat candidate list, where Limagrain has 7 out of the total 11 varieties up for recommendation to join the 2019-20 AHDB Recommended List, spread across almost every quality sector.



    We are particularly excited about our soft feed variety LG Skyscraper, which is the highest yielding wheat candidate at 109% and will potentially be the overall highest yielding wheat variety, should it gain full recommendation to the 2019-20 List, says Les Daubney, marketing director for arable seeds, with Limagrain UK.

    LG Skyscraper 4.jpg

    LG Skyscraper’s very high yield shows a significant 4% increase over the control feed variety KWS Santiago in treated trials and demonstrates that the variety is capable of competing with many of the high yielding feed varieties that have been added to the AHDB RL in the last couple of seasons.


    “What is also exciting and really valuable on-farm, is that this yield potential has been consistent across both seasons and regions.”


    “With excellent grain and end-use quality attributes on offer, LG Skyscraper is bucking the trend that soft wheats don’t yield or have the desirable quality characteristics of the hard Group 4’s as here is a soft wheat that does both - and very well,” Les says.

    les Daubney 2.JPG


    After two years of official testing, based on these excellent quality attributes, LG Skyscraper has been rated as a positive for distilling, making it an attractive proposition for growers in the north. The variety has a Hagberg Falling Number (HFN) of 216 and specific weight of 77.7, in comparison to the hard feed wheat KWS Santiago, with a HFN of 188 and specific weight of 76.3, and the biscuit wheat Zulu, with a HFN of 229 and specific weight of 76.4.

    LG Skyscraper has a pedigree of (Cassius x NAWW29) x KWS Santiago. This balance of genetics brings excellent disease resistance to the variety; LG Skyscraper has good resistance ratings for mildew (7), yellow rust (8), brown rust (6) and for Septoria tritici (6).


    This combination of disease resistance offers a variety with improved ratings over many of the feed varieties commercially in the market at present – which is also reflected in its excellent untreated yield performance.

    Agronomically, LG Skyscraper shows itself to be a robust and flexible variety; Limagrain data however suggests that the variety is not as tall as the official figures indicate and 2017 lodging data should be viewed with caution as it was an erratic season with regards to plant growth, and a difficult season for targeted agronomic programmes,” advises Ron Granger, arable technical manager at Limagrain.


    “Our data shows the variety to be high tillering with a semi-prostate winter growth habit, and quicker plant development in the spring - similar to Evolution. It is early maturing –the same as JB Diego and Skyfall.”

    “What this translates into in the field is that LG Skyscraper is suitable for drilling from the third week of September onwards and also offers a later drilling opportunity in regards to the blackgrass control scenario,” Ron says.


    Limagrain data suggests that LG Skyscraper performs well as a second wheat, (3-year data set) and this is an area in which we will continue to generate more information. LG Skyscraper also has Orange Wheat Blossom Midge Resistance (OWBM); an important trait that is of increasing value in wheat varieties due to restrictions on insecticide products.


    So to summarise, for those growers who are looking to grow a Group 4 and maximise their return on investment, they would have to go far to find a better variety than LG Skyscraper, with its very high yields, grain quality attributes and agronomic merits.


    LG Jigsaw is a very different variety; it is a high yielding hard feed wheat that offers many valuable agronomic characters and it suits the earlier drilling opportunity. LG Jigsaw is the highest yielding hard feed wheat candidate and is very similar to its parent KWS Santiago, regarding both treated and untreated yield potential.

    LG Jigsaw.jpg


    “From a pedigree of KWS Santiago x Revelation, it’s easy to see where these strong attributes come from. KWS Santiago has shown itself to be a consistent, high yielding, safe on-farm variety, and Revelation has proven excellent disease resistance ratings and fits the early drilling slot well,” says Les Daubney.

    LG Jigsaw also has similar straw characteristics to KWS Santiago and responds well to PGR treatments. It’s disease resistance profile is excellent, with a solid rating of (6) for Septoria tritici, (8) for yellow rust, (7) for brown rust and a very good rating of (7) for eyespot.


    The variety offers genetic resistance to OWBM and has Pch1 Rendezvous eyespot resistance; very important traits that are valued by growers.


    “Our data suggests that LG Jigsaw is a very high tillering variety, with a very prostrate winter/spring growth habit and later spring ear development. In Limagrain trials last spring, it was really noticeable that LG Jigsaw held onto its high tiller numbers when many other varieties lost tillers due to the very dry spring - and it’s all of these factors that come together to make the variety suitable for the earlier drilling slot,” adds Ron Granger.


    “It is a later maturing variety and with limited data, looks very good in the second wheat slot, but this is an area that we are continuing to trial.”

    Matt Shand, arable wholesale seeds manager for Limagrain UK, is very pleased with the level of interest in these varieties from across the industry and believes that this interest will only increase for both varieties going forward.


    “Whilst LG Skyscraper and LG Jigsaw are the two stand out candidates, the breadth of other candidate varieties on offer all have specific characteristics that will find favour on- farm for their agronomics, whilst meeting specific end-user requirements.”

    Aquila’s vigour shines under pressure


    The superb autumn and spring vigour of Limagrain’s new oilseed rape variety; Aquila, is making a big impression on growers that could see it challenge market leaders in 2018/19.


    The restored hybrid is officially recommended for east/west regions, but Openfield’s Lee Bennett says evidence suggests it suits almost any location, soil type or drilling slot. Indeed, Aquila was the top variety at the Croft variety trials near Darlington last year and many crops in northern England and Scotland have performed as well as further south, he says.


    “It’s exciting to find a variety that can match or beat established favourites. Aquila has strong vigour in autumn and spring, good phoma and light leaf spot resistance, pod shatter resistance, stiff straw and doesn’t grow too tall.”


    Yields well despite tough conditions



    Richard Wainwright, who farms 510ha on the edge of the North Yorkshire Moors, is growing Aquila for the second time after last year’s crop, direct drilled after wheat, yielded an impressive 5t/ha.

    “It went in later than usual, but still established well. We’re only sowing 30 seeds/sq m, targeting 15-17 plants/sq m in March, so crops can look a bit thin at first. But once we got to the end of March, it grew and branched out amazingly and yielded 5t/ha.”


    This season’s 30ha, which was direct drilled after winter barley on 19th August, has again gone into a challenging situation as the field is surrounded by woodland on three sides, resulting in significant pigeon pressure. Despite this, and difficult weather earlier in the year, the crop is doing well, he says. “It showed good autumn vigour and really got going once we reached mid-April.”


    “It’s got really good disease ratings and we’ve never felt it’s let itself down due todisease. Pod shatter resistance is another good attribute to have.”


    Mr Wainwright adds: “There is a myriad of varieties coming through the breeding system, promising all sorts of things. I’m looking for a ‘keeper’ and on the evidence of last year and this year’s crop so far, Aquila looks to fit that bill. We’ll see how it yields, but at this stage I’ll certainly grow it again next year.”


    Aquila stands out from others



    Aquila’s autumn and spring vigour has similarly impressed Lincolnshire farmer Daniel King, who has 80ha (200 acres) of his 280ha (700 acres) of oilseed rape down to the variety, at Pasture Hill Farm, Edenham near Bourne.


    “It’s our first year growing Aquila and so far it looks far superior to anything else, which includes Extrovert and Campus. It established really well in the autumn, and sprang out of the blocks quickly in the spring when other varieties seemed to struggle to get going in cold, wet conditions.”


    “We’ve never had an issue with Extrovert in the past, but it doesn’t look a patch on the Aquila, while Campus also looks poor.”


    Oilseed rape was sown from 20th August onwards, using a 6m Cousins Micro Wing shallow subsoiler set to 600mm leg spacing. A 14-14-0 liquid starter fertiliser was included with seed, to boost establishment on the predominantly heavy land.


    “We’re surrounded by woodland which means there’s a lot of pressure from pigeons and deer, so crops have to get away quickly,” Mr King says. “Last year was also the worst we’ve seen for flea beetle activity, but thankfully crops grew away before there was much damage.”


    Aquila’s strong disease resistance - particularly to phoma (rated 8) and light leaf spot (6) is another important attribute, as it gives some flexibility around spray timings, he adds.


    “We treat all varieties the same with a robust programme of two autumn and two spring fungicides, but having a variety with a good disease profile does buy time if we can’t get on to spray.”


    He also values Aquila’s pod shatter resistance, which should reduce harvest losses and benefit yield.


    Mr King says Aquila is likely to be the dominant rape variety sown this autumn, given it’s performance so far, although he will retain a mix of varieties to spread risk.

    Lee Bennett acknowledges that sowing vigorous varieties early can sometimes increase the risk of producing over-thick canopies that are at greater lodging risk, but insists Aquila is a good option in early drilling slots due to its stiff stems.


    “It’s true slot is the mainstream sowing window, starting in the third week of August - that’s where it really shines. But it works well grown early or late.”


    [Summary box] Aquila’s key attributes


    • Strong hybrid vigour in autumn and spring
    • Good disease resistance
    • Pod shatter resistance
    • Stiff straw
    • High oil content

    Consider clubroot risk in 2019 OSR plans


    Clubroot is an increasing problem affecting oilseed rape crops well beyond traditional hotspot areas, and more must be done to manage the risks.


    The disease is typically most severe in wetter regions with a history of mixed cropping, such as Scotland and northern or western England, but isolated cases occur across the UK, with losses exceeding 50% of yield potential in the worst-affected crops.


    “Clubroot is still a relatively niche problem compared to diseases like light leaf spot, but we’re seeing more cases around the country, and for growers in hotspot areas there’s a high proportion who have at least one field affected,” Limagrain’s Vasilis Gegas says.


    “It mirrors what we’re seeing elsewhere in Europe where clubroot incidence is increasing, possibly as a consequence of climate change resulting in more frequent, milder and wetter winters. It is why the disease is our most heavily-invested oilseed rape breeding trait, aside from turnip yellows virus.”

    Resistant hybrid varieties such as; Archimedes, offer a valuable option for growing oilseed rape on infected land, and newcomers such as; Alasco, promise to virtually eliminate the “yield drag” associated with resistant varieties in the past, says Dr Gegas.


    “Alasco is the next generation of clubroot resistant varieties, with a yield close to mainstream varieties and oil content 3% higher than Archimedes.”


    Alasco retains and enhances many of the traits in Archimedes that were developed specifically for northern areas, such as robust light leaf spot resistance, short stiff straw, pod shatter resistance and early maturity.


    Agrii northern seed sales manager; Rodger Shirreff, who plans to try Alasco for the first time this autumn says, Archimedes has served growers well over recent years, allowing good yields to be produced from clubroot-infected land.


    The variety’s vigorous autumn establishment is particularly beneficial as it allows the taproot to establish quickly, providing a solid foundation to build on. It is also one of the quicker varieties to resume growth in the spring, he notes.


    “Clubroot is a widespread issue in Scotland, that’s been perpetuated by tight (one year in four) rotations. But it’s not limited to Scotland; we’re also seeing increasing problems further south, so more growers are moving to resistant varieties.”


    [X-head] Protect future resistance

    While genetic resistance is very effective, Dr Gegas warns the clubroot pathogen (Plasmodiophora brassicae) is capable of evolving and overcoming resistance in certain circumstances, so genetics must be supported with good husbandry and stewardship.


    He advises against growing resistant varieties unless clubroot is a significant problem and says extended rotations of at least one year in seven or eight, and careful soil management must also be used to control disease.


    “There’s a lot to gain from making soil conditions unfavourable for clubroot by liming to increase the pH to 6/7, prior to drilling or improving drainage of waterlogged areas. Wider rotations alone aren’t the answer because the pathogen can survive for such a long time in soil.”


    Commercial soil tests can be useful for confirming presence of the clubroot pathogen, but should only be a guide, he notes. “We often find many soils contain the pathogen, but that doesn’t mean disease will develop or there will be an impact on yield, as it still requires the right environmental conditions.”


    “Last autumn was mild and wet so we saw a lot of symptoms, and if climate change leads to frequent, milder and wetter winters, we could well see a wider spread of the disease.”


    Mr Shirreff says clubroot can sometimes go unnoticed until significant yield declines are seen, so vigilance is essential if growers suspect there may be an issue.


    Clubroot incidence tends to be patchy and leads to affected plants wilting in hot, dry weather, becoming stunted or dying completely as the galls that form on the tap root restrict water and nutrient uptake.


    He also points out that volunteers from previous oilseed rape crops can harbour the disease and need to be controlled.


    “We’ve seen situations in the past where a resistant variety has been grown and it’s appeared to have broken down to the pathogen, but in fact it’s instead the non-resistant volunteers that have grown up within the crop and then succumbed to the disease. Examples like this really highlight the strength of growing resistant varieties.”
