Early OSR RL variety trials show yields 0.49t/ha down on four-year average

The first three winter oilseed rape (WOSR) harvest results for 2016 from AHDB’s Recommended Lists variety trials have been published showing yields down nearly half a tonne per hectare (0.2t/acre).

First OSR RL trial yield data available

 

The 2016 gross output value from the first three trials from sites in Kent, Suffolk and Herefordshire is 5.1t/ha (2.04t/acre). This is 0.49t/ha (0.2t/acre) below the four-year average of 5.59t/ha (2.24t/acre), according to AHDB.

 

The three sites show variation in average gross output yields, with Hereford achieving 5.51t/ha (2.2t/acre) but Suffolk averaging 4.89t/ha (1.96t/acre).

 

Currently, higher-yielding varieties include Picto (113%), Campus (111%), Elgar (109%), Angus (109%), the HOLL variety V316 OL (107%) and Windozz (106%). Three of these six varieties are conventional varieties and three restored hybrids.

 

The 2016 gross output values provide a good snapshot of variety performance this year. However, the four-year average values provide a better picture to variety performance over seasons, explained AHDB.

 

Based on the four-year average values, the highest yielding varieties to date are Elgar (109%), Windozz (108%), Alizze, Wembley and V316 OL (all 107%), and Campus (106%), said AHDB.

 

Looking at the four-year averages, the clubroot resistant variety Mentor has a gross output of 101% and the turnip yellows virus resistant variety Amalie, 97%.

 

Gross output values for the candidate varieties in 2016 – based on limited information –show good yields from the conventional variety Flamingo (113%) and the restored hybrid variety Aquila (112%). The relative yields are likely to change as more results are published, said AHDB.

 

The candidate variety Ergo (94%) is a high erucic acid rape variety.

 

For winter OSR, yields are reported as a gross output, which is seed yield adjusted for oil content. The values are represented as a percentage of the control varieties – PR46W21, DK Cabernet, PT211 and Trinity.
