02/09/2013 HGCA results for winter wheat
Latest harvest resultsWinter wheat
With two HGCA Recommended List Trials validated, it is early days to form a full picture of how current HGCA Recommended List varieties have performed, comments HGCA senior research and knowledge transfer manager, Dr Simon Oxley. The two sites in Lincolnshire are on contrasting soil types, but both have achieved a good yield averaging 10.14t/ha which compares favourably with the 5 year average of 9.94t/ha. The high yields in 2013 came from the group 4 feed varieties Dickens with a yield of 108% of the average of the control varieties, Conqueror (108%), KWS Santiago (105%) and JB Diego (105%). The group 3 variety Cocoon (105%) also has a good yield. When selecting varieties, the 5 year averages are a better measure of performance over several seasons.
There are two more yield results in this week for winter barley, from Cheshire and Aberdeenshire. The average winter barley yields are 8.43 t/ha which is down on the five year average of 8.72 t/ha. The Aberdeenshire site has shown a lacklustre performance with an average of 6.63 t/ha, but in Cheshire, the average was a very respectable 9.12 t/ha.
Looking at the average based on all the results, the 6-row hybrid Volume has achieved 106% compared with the control varieties, and the conventional 6-row feed variety KWS Meridian achieved 105%. For 2-row feed, KWS Glacier (107%) and Retriever (108%) have performed well. Looking at this year’s candidate varieties, Harlequin and Tetris have performed well on yield. When selecting varieties, the 5 year averages are a better measure of performance over several seasons.
Winter oilseed rape East/West
Winter oilseed rape gross output yields in 2013 are averaging 5.40 t/ha, close to the four-year average of 5.41 t/ha. The four-year averages are a better measure of performance over several seasons and Marathon, PR46W21 and PT211 currently standing at 103% of the average of the control varieties. The candidate varieties Charger (106%) and Incentive (105%) have performed well.
Winter oilseed rape North
With two results in for the north region, it is early days to come to any conclusions. As such, use the four-year average gross output yields to gauge performance over several seasons. The two trials are averaging a gross output of 5.29 t/ha which is above the four-year average of 5.18 t/ha. Anastasia has performed well both in 2013 and the past four years. Artoga has also had a good year in 2013 based on the limited information.
