12 varieties added to 2026 Forage Maize Descriptive List
Twelve new varieties have been added to the British Society of Plant Breeder’s 2026 Forage Maize Descriptive Lists (DL).
The new entrants on the 2026 Favourable First Choice List are KWS Zimo, KWS Reo, Amarola, Agrolino and KWS Portabello from KWS, SU Addition from Bayer and LG31206, Harmony and LG31152 from Limagrain. DKC2742 from Bayer, and MAS 195P and Clifford from Bright Seeds, have been added to the Favourable Second Choice List. LG31152, Harmony, KWS Portabello and KWS Reo have also been included on the First Choice List for Less Favourable sites. No further varieties have been added to the Very Favourable list for 2026.
Favourable sites DL
Of the new varieties added to the Favourable sites DL, Niab forage crop specialist Ellie Roberts highlights KWS Zimo as the highest yielding new variety at 19.6 t DM/ha, with a metabolisable energy (ME) yield of 230 kMJ/ha and starch yield of 6.90 t/ha. Bayer’s SU Addition is the next highest yielder at 19.5 t DM/ha, with an ME yield of 221 kMJ/ha and starch yield of 6.02 t/ha. KWS Reo has the highest starch yield on the list at 7.08 t/ha.
Less Favourable sites
Of the Less Favourable sites DL varieties, Limagrain’s LG31152 is the highest yielding new variety at 18.5 t DM/ha at 40.0% DM, with KWS Reo giving the highest ME yield of the new varieties on the list at 222 kMJ/ha and highest starch yield on the less favourable first choice list at 7.29 t/ha at 37.0% dry matter.
“All the new varieties score well for both early vigour and standing power,” advises Mrs Roberts.
Crop trials organisation Niab coordinates the forage maize variety trials programme on behalf of BSPB. Halfway through yet another challenging growing season for UK maize growers Mrs Roberts remains positive that the majority of trials sites across the country have had enough moisture in time to grow away.
“With 13 trial sites across England, the locations and circumstances not only give the varieties a robust testing across UK conditions but also aims to provide sufficient data on each variety and allows for the risk of some trial losses. Fortunately, the lack of moisture at establishment has, so far, only led to some trial failure due to uneven establishment at two sites this year.”
Mrs Roberts warns that the timing of late summer/autumn rainfall can impact harvest, particularly after a long dry period as maize plants may be drying rapidly when wet soils prevent access for harvest.
“The most critical element of the forage maize variety trials programme is that all varieties in a trial have fair and consistent treatment within each trial to ensure reliability and validity of the published data. The continuing challenging UK growing conditions over recent growing seasons continue to put these maize varieties through rigorous performance testing.”
