The 2020/21 AHDB Recommended List features 27 new cereal and oilseed varieties, many boasting a step up in disease resistance, with oilseed rape yields taking a particularly big leap.
Oilseed rape varieties saw sharp rises in yield, with thirteen new varieties added to the RL - three gaining automatic recommendation based on gross output yield.
Standout conventional variety, Acacia has a yield of 110 per cent of control in the East/West regions – a four point advantage over the previous highest yielding OSR on the RL, Aspire (106).
It has good resistance to lodging and stem stiffness but is lower on disease ratings with a 5 for phoma stem canker and a 6 for light leaf spot.
New hybrid varieties, Ambassador, Aurelia and Artemis, all by Limagrain trump Aspire for gross output, closely followed by the conventional variety, Aardvark.
Aurelia is expected to be particularly attractive due to its combination of high gross output (108), high resistance to lodging (8 based on limited data) and high disease ratings with an 8 for phoma stem canker and light leaf spot, and turnip yellows virus (TuYV) resistance.
Ambassador follows closely behind in terms of disease package, more suited to the E/W region.
Five new OSR varieties have been recommended for specific purposes including clubroot resistance, herbicide tolerance, semi-dwarfing and HEAR.
Crocodile offers a step up in yield for clubroot resistant varieties, with an East/West gross output of 105. Although slightly lower yielding at 102, Croozer has good disease resistance with a 9 for stem canker.
Both are for use on clubroot infected land only.
