A trio of ‘triple layered’ oilseed rape (OSR) varieties could soon be available to UK growers, DSV announced at Cereals 2018.
The ‘triple layer’ refers to a combination of disease resistance traits and physical properties enabling production of high yields and oil contents with minimal agronomic input, according to DSV managing director, Mike Mann.
The three varieties, WRH 532 (Dazzler), WRH 527 (Darling) and WRH 530 (Award), are now going through UK testing and will be the first commercially available varieties to combine a high level of phoma stem canker and light leaf spot resistance with turnip yellow virus and pod shatter resistance.
DSV international oilseed rape product manager, Dr Alex Doring said: “The layering process is a continuation of DSV’s PNN (post neonicotinoid) initiative where we started to breed varieties with early vigour, good compensation ability and optimised plant architecture.
“All varieties with layering still have these characteristics, but with additional layers of disease resistance and yield protection traits."
Mr Mann said: “The varieties have been developed specifically to help growers meet the future challenges of reduced chemistry, increasingly variable growing conditions and the need to reduce input costs to be more competitive on a world stage.”
The first of these varieties is expected to make it onto the Candidate List this December, according to DSV.
The company hopes to add additional layers such as verticillium wilt tolerance and clubroot resistance to future varieties.
