OSR is a crop beset with problems, but plant breeders are working hard to create new varieties which are more resilient. CPM finds out how traits are being bundled into hybrids to help growers manage risk. When we started working with these traits, there was a trade-off for yield. By Lucy de la Pasture While plant breeders are yet to come up with the answer to today’s most pressing pest problem, cabbage stem flea beetle, advances in breeding technologies have seen substantial progress in the introduction of traits to help reduce yield fluctuations. For growers where OSR remains a viable option, the ‘bundling’ of risk management traits has been made possible by these precision breeding techniques. And Limagrain is using them to bring UK-specific varieties to market that can help growers mitigate seasonal yield variability, explains the company’s senior OSR breeder, Dr Vasilis Gegas. TuYV resistance is one of the traits that will be bundled with several other traits as standard in new varieties. “The definition of that variability is the gap between a variety’s genetic yield potential and the yield observed on farm at harvest, which can be influenced by a considerable number of factors. “The environment is…
