ITS first ‘double layered’ oilseed rape variety with full genetic resistance to turnip yellow virus (TuYV) was aired by DSV UK at the recent CropTec event.

The hybrid Temptation, which was drilled in RL candidate trials this autumn, is the company’s first ever oilseed rape to feature full genetic resistance to TuYV. Its managing director, Mike Mann, commented: “There are worrying signs that TuYV is becoming a growing threat to UK producers, with indications it is now endemic across the UK with a growing number of cases, so there is real pressure on breeders to address this through genetics.

“It’s a potentially serious situation as the disease can have a significant affect on both yields and oil content and can rob you of production without you really knowing it. Even insecticide treated sites can show 5-7% loss, and in an untreated situation this can reach 20% or more," he said.

“Working with our colleagues in Germany, we’re confident that virtually all new DSV varieties will carry TuYV resistance with trials across Europe showing very impressive results.’’

Temptation is the first to be introduced to the UK and also has excellent early vigour, with outstanding growth in the first 45 days. “It is also our first double-layered PNN [post neonicotinoid] variety. In the past DSV’S single layered PNN varieties have had multi-gene resistance to light leaf spot and phoma stem canker, but Temptation adds another additional layer with TuYV resistance,” added Mr Mann, who added that DSV also had three new wheat varieties in their second year of National List trials, which are showing promise.

“We have a high yielding feed wheat with excellent disease portfolio, a group 3 biscuit variety with strong agronomic characteristics and an excellent bread maker featuring the highest combination of Hagburg falling number, specific weight and protein levels of all the current NL2 varieties and controls.”
