Two new additions to the Group 2 milling wheat list – KWS Palladium and Mayflower – are expected to help the milling industry spread risk, after it has become increasingly reliant on a small group of varieties.
Speaking at the AHDB Recommended List (RL) launch, RL project manager Dr Paul Gosling said: “These new varieties have very good grain quality and very good disease resistance.
Millers are very keen to have them on the list, which had become somewhat reliant on Extase.”
KWS Palladium has a high Hagberg of 315 and has given good protein (13.1%) under a regime to achieve milling specification.
Dr Gosling added: “In terms of hitting milling specification, it is a promising variety with high Hagberg, good specific weight and high protein content.
For growers that are a little bit risk averse, this is a good variety for them. It is also now the earliest variety on the RL.”
A couple of points below Extase’s gross output in the East at 98%, Mayflower from Elsoms is classified as a ukp bread wheat for export.
“It is better on grain quality than Extase and Siskin, with a Hagberg of 294 and as good as Extase for specific weight at 78.5kg/hl,” Dr Gosling said.
Both varieties have good disease packages, with untreated yields of 90%, and Mayflower has the New options for millers Additions to the AHDB Recommended Lists and PGRO Descriptive Lists for 2022/23 showcase strong all-round disease packages, good grain quality and some flexibility around drilling.

highest rating for resistance to septoria tritici for a breadmaking variety of 8.4.
After Group 3 biscuit winter wheat varieties suffered disproportionately from increased susceptibility to septoria in the 2020/21 season, the latest RL has three new Group 3s which feature a different genetic basis for their resistance to the disease, which should be more durable, according to AHDB.
KWS Guium is the highest yielding Group 3 on the new list at 102% and also has unusually good grain quality for a Group 3, Dr Gosling said.
“Hagbergs tend to be lower in Group 3s but Guium has a very good Hagberg at 255 and very high specific weight of 78.1kg/hl, making it the highest on the new [Group 3] list.”
It is recommended for the UK and is rated as ‘medium’ for distilling.
“Guium is a bit late which might be something to consider for some growers,” he added.
Late sowing Also with a high Hagberg is new addition, KWS Brium at 268, with a high specific weight of 77.3kg/hl.
Recommended for the East region only, limited data for RGT Rashid suggests it has high yield potential in a late-sowing situation.
On the soft feed variety list and also performing well in late-sowing situations, according to limited data, is RGT Bairstow.
It is rated as ‘good’ for distilling and is the highest yielding soft milling feed variety (103%) but has a low specific weight of 75.9kg/hl.
It also has the highest second wheat yield of any recommended variety at 104.3%.
RGT Stokes has given very high treated yields in the West region (105%), with limited data suggesting it is also very high yielding in the North region (104%).
It is likely to attract a strong following here thanks to its good distilling rating.
The variety produced the overall highest alcohol yield in 2021 of RL candidates and control varieties in Scottish Whisky Research Institute testing.
It has a low specific weight (75.3kg/hl) but good Hagberg (248).
Three new hard milling Group 4 wheats were added, including Champion as the highest yielding variety on the RL at 106%.
Champion showed high yield potential across a range of rotational positions, soil types and sowing dates.
It has a low specific weight (74.8kg/hl) but very high resistance to septoria at 8, combined with resistance to orange wheat blossom midge, resulting in a high untreated yield of 90%.
Also showing high yield potential across different scenarios, KWS Dawsum (104%) has a high Hagberg of 304 and a specific weight of 79.4kg/hl.
It has performed particularly well in the West region (106%), with limited data suggesting the same yields in the North.
