Oilseed rape summary
Results are in from 10 Recommended List trial sites and the control varieties are averaging 5.59t/ha (gross output), which is slightly higher than the five-year average (5.47 t/ha).
However, this headline figure masks a clear split between the trials in England, which struggled (4.80 t/ha) in the conditions, and those in Scotland, which avoided the worst weather and beetle effects (6.38 t/ha). In fact, the controls in the trial at Kincardine in Fife averaged 6.99 t/ha.
Oilseed rape variety selection
Some surprising results occurred in 2020. UK recommended hybrid varieties Ambassador and Aurelia are the highest yielding (107%), but the conventional control variety Campus, which is no longer on the Recommended List, is just behind (105%).
Other varieties performing relatively well include UK recommended hybrid Expansion (104%), the East/West recommended hybrid Darling (103%) and the high oleic acid variety V 316 OL (101%).
Meanwhile, Acacia, the highest yielding UK variety on the RL, languishes down on 101%. Newly recommended conventional variety Blazen, recommended for the North (99%), and hybrid Dazzler, recommended for the East/West (98%), also struggled – along with described varieties PX131 (semi-dwarf) and high erucic acid variety Resort (92% and 87%, respectively).
