Oilseed rape summary

Results are in from 13 Recommended List trial sites and the control varieties are averaging 5.13t/ha (gross output), which nearly matches the four-year average value (5.14 t/ha), with the traditionally high-yielding northern trials pulling up the average.

Trials in Aberdeenshire (mean of controls 6.39 t/ha) and Fife (mean of controls 6.11 t/ha) have yielded especially well. Although trials further south have not yielded as highly, fewer trials have been lost to flea beetle and drought than in recent years.

With just a couple of trials still to report, these results are likely to closely match the final results.

Oilseed rape variety selection

The conventional varieties Acacia and Campus (105%) are leading on gross output yield, just ahead of hybrids Ambassador (104%) and Aurelia (102%). Acacia and Campus have performed especially well in the Fife and Aberdeenshire trials, though they also performed well in some of the southern trials, notably the Norfolk trial.

Crocodile (101%), which is an East/West variety with a specific recommendation for resistance to clubroot, has performed well in 2021, as has UK recommended clubroot-resistant variety Chrome (100%).

Herbicide-tolerant varieties have performed a little below par in 2021, with the exception of East/West recommended variety PT279CL (94%).
