After 20 years of research and testing, LSPB has commercially launched two oilseed rape varieties containing a new resistance gene – RlmS – which claims to offer greater protection against phoma. CPM explores the breakthrough in genetics. Now is the time to have a new resistance. By Charlotte Cunningham Since Rlm7 came onto the scene, oilseed rape has enjoyed the protection the gene has brought against phoma – arguably one of the most important diseases in OSR production. And while the gene continues to be an effective part of the strategy, there’s no escaping the concern that reliance on any kind of singular resistance will undoubtedly, eventually, lead to challenges. This, teamed with the effects of global warming and the wet and mild winter often worsening the prevalence of resistant pests and diseases give considerable cause for breeding to focus on the ‘what’s next’ of the resistance strategy. Dr Christian Flachenecker is leading the winter OSR breeding programme at NPZ. And it was this sentiment exactly that has led to the birth of the new winter OSR varieties containing the RlmS gene – a product of more than 20 years of hard work by breeders NPZ – LSBP’s exclusive…
