Download PDF After more than 20 years in development, a brand-new resistance gene against phoma has been brought to market in the form of a high yielding, robust, oilseed rape variety. CPM reviews Flemming. To discover a new ‘R’ gene at such an important time is great for the industry. By Charlotte Cunningham The Rlm7 gene has long been the cornerstone of phoma resistance in oilseed rape, but just like chemistry, an over-reliance on any kind of protection is likely to lead to breakdowns in efficacy somewhere along its lifespan. Foreseeing this challenge, LSPB has been working away on breeding a new resistance gene over the past 20 years. And now, with reported breakdowns of Rlm7 in Europe, the new RlmS gene could offer real, timely potential for OSR growers. To put this breakdown into context, 2020 studies carried out by Marie-Hélène Balesdent in France showed that Rlm7 is losing its efficacy – with only 20-30% non-virulent races identified from 240 races, analysed across eight trial sites. In contrast, the new RlmS gene proved to be 100% effective. However, it’s one thing to create a new gene, but entirely another to be able to deliver that in a package which…
