Download PDF The loss of neonicotinoids has added insult to injury for growers struggling with TuYV pressures, meaning varieties with “built-in” resistance are more important than ever. CPM tracks the journey of one breeding programme, from lab to field. More than 10 years ago, our breeders estimated that the TuYV could become a major threat to OSR. By Charlotte Cunningham Turnip Yellows Virus – carried by the peach-potato aphid (Myzus persicae) – has long been the arch nemesis of oilseed rape, causing potential crop losses of up to 30% in the worst-case scenario. Until recently, neonicotinoid seed dressings provided fairly good control of aphids, keeping the yield-robbing virus at bay. But following the loss of the crop protection product, growers have been left with a limited number of options. However, several OSR breeders had the foresight to start researching whether varietal control was possible long before the loss of neonics made the genetic route necessary, meaning growers now have a range of TuYV-resistant varieties at their disposal. Turnip Yellows Virus – carried by the peach-potato aphid (Myzus persicae) causes potential crop losses of up to 30% in the worst-case scenario. One of the early developers of “built-in” TuYV resistance was…
