With more data now in from the key spring barley growing area in Scotland, the 2020 average treated yield of control varieties from 14 AHDB Recommended List (RL) spring barley trials is 7.94 tonnes/hectare, ahead of the five-year average (7.58t/ha).
Trials data in from Banffshire (9.73t/ha) and Angus (9.03t/ha) has pushed the average up, though it is not all good news from Scotland, with the controls in the Aberdeenshire trial yielding only 7.30t/ha. Untreated control yields in 2020 (7.43t/ha) are also above the five-year average (6.84t/ha), reflecting a generally low disease year, says AHDB.
Treated results for malting varieties show the control variety LG Diablo, along with the newly recommended variety SY Tungsten both at 103 per cent. Diablo did particularly well in the Norfolk trials, yielding 107 per cent at both.
Just behind these two varieties are the established control varieties Cosmopolitan and Laureate on 102 per cent. The newly recommended UK varieties, SY Splendor and Firefoxx and the newly recommended variety for the West region, Iconic, remain behind these on 101 per cent.
The two feed varieties on the list, Fairway and Prospect, both newly recommended, are on 102 per cent and 101 per cent, respectively, in the treated trials.
In the untreated trials, Cosmopolitan has come out top, so far, at 105 per cent, ahead of Iconic and Prospect, both on 103 per cent, according to AHDB.
Of candidate varieties, potential malting variety Skyway is performing well on 105 per cent, says AHDB, ahead of potential malting varieties Cadiz, SY Fable and SY Emerson, all on 102 per cent. Skyway also performed well in untreated trials (106 per cent), with Cadiz on 104 per cent and SY Fable and SY Emerson on 103 per cent. LG Mermaid is the only candidate feed variety that has been National Listed, so far, with a yield of 104 per cent, in both treated and untreated trials.
Harvest results for AHDB RL spring wheat trials from five sites show Group 4 varieties Hexham (109 per cent), KWS Kilburn (107 per cent) and KWS Talisker (106 per cent) leading on yield.
However, the top-yielding Group 2 bread wheat KWS Cochise is only just behind (105 per cent), with Group 2s KWS Chilham (103 per cent) and newly recommended variety KWS Giraffe (101 per cent) just behind that. Group 1 variety Mulika has performed relatively well so far (98 per cent). On quality, KWS Giraffe has maintained the strong quality characteristics it displayed when recommended last year, says AHDB.
Of spring wheat candidate varieties, on five-year average figures, feed variety WPB Escape is performing well on yield (107 per cent), ahead of potential bread-making variety WPB Arcade on 104 per cent. WPB Arcade looks to have good quality characteristics from the 2020 data, including Hagberg falling number and specific weight, however, it is its baking quality that will determine the final classification, says AHDB.
