Oilseed rape RL trial yields ‘below the four-year average’

Winter oilseed rape yield data from seven trials – Hereford, Kent, Norfolk, Northumberland, North Yorkshire and Suffolk (x2) – have been added to AHDB’s Harvest Results pages.

The average gross output value of the control varieties is 5.03 tonnes/hectare, which is below the four-year average value of 5.24t/ha.

 

Results from individual trial sites should not be used to make conclusions on variety performance. This is especially true for winter oilseed rape, as performance tends to be more variable than cereals, warns AHDB.

 

The 2019 gross output value of the control varieties (5.03t/ha) is below the four-year average (5.24t/ha). To date, the conventional varieties Aspire (111%) and Ballad (107%), and the restored hybrid varieties Temptation (107%) and Architect (107%) have performed well, according to AHDB.

 

These varieties have UK recommendations (for both the East/West and North regions), with Temptation and Architect having specific recommendations for resistance to Turnip Yellows Virus (TuYV). Aspire also has resistance to TuYV.

Four-year average

 

Based on the four-year average values, the highest-yielding varieties to date are Aspire (106%), Ballad (104%), DK Expansion (103%) and Crome (103%).

 

Crome has a UK specific recommendation for resistance to clubroot. In addition to Aspire, varieties with TuYV resistance have gross outputs of 102% - Temptation and 100% - Architect. PT279CL, which has a UK specific recommendation for tolerance to specific imidazolinone herbicides (a Clearfield variety), has a gross output of 95%.

 

Gross output values for the candidate varieties, based on the preliminary four-year averages, currently show that the conventional variety Acacia (109%) and the restored hybrid varieties Aurelia (107%), Ambassador (106%) and Artemis (106%) have performed well, according to AHDB.
