RL Winter Wheat Harvest trials – 29-9-15

This weeks winter wheat results bring the total harvest results to 29, from Kent up to Aberdeenshireand across to Northern Ireland, reports AHDB Cereals & Oilseeds.

Control yields

Average-yield ofwinter wheat control varieties in 2015 is 11.7 t/ha, 1.3 t/ha above the five-yearaverage.

Yields reportedthis week have a wide range with the Yorkshire site at Cawood, drilled on 2ndOctober after spring beans, achieving the top yield of 17.73t/ha for the average of the control varieties.However, the site in Aberdeenshire, drilled on 1st October afterpotatoes, averaged 8.45 t/ha.

The controlvarieties which are used to calculate a yield of 100% are JB Diego, Gallant,Invicta, KWS Santiago and Crusoe.

Variety performance

The Group 4hard-feed varieties KWS Santiago and KWS Kielder continue to perform well witha yield of 105%, while Evolution, Dickens and Costello have a yield of 103% ofthe control varieties.

Soft Group 4feed varieties performing well include Viscount (103%), Leeds (102%) andTwister (102%).

Yield alone isnot the mark of a good quality variety. Looking at yields of the quality groupshowever, the nabim Group 1 varieties Skyfall (102%), KWS Trinity (101%) andCrusoe (98%) all look favourable.

The nabim Group2 variety KWS Lili (103%) currently stands out, whilst the Group 3 biscuitquality variety Britannia (104%) looks particularly impressive on yield.

Five-year averages

When selectingvarieties for next season, the five-year average values give a betterrepresentation of performance in different seasons.

At this stage, threeGroup 4 hard-feed varieties are performing well Reflection (105%), Evolution(105%) and KWS Santiago (105%).

Skyfall (101%)leads the Group 1 quality wheats on yield and KWS Lili (104%) a Group 2 qualitywheat and Britannia (104%) a Group 3 biscuit wheat have yields comparable to manyhard and soft feed varieties.

Candidate varieties

Looking to thefuture and the candidate varieties, it is too early to identify their qualityperformance, but on yield the potential bread making variety KWS Siskin (105%)and the potential hard feed variety KWS Silverstone (106%) are performing well.


As far asprotein is concerned from these trials, Crusoe achieved an average of 12.2%,while KWS Trinity has the highest Hagberg falling number average of 326seconds. Cubanita has achieved the best specific weight average of 80.4 kg/hl.

Not all thesetrials are managed to a milling protocol and not all trials are in areas wherethe milling market would be targeted.  Samples used in the milling tests are takenfrom other trials not reported here.
