The latest Recommended Lists aim to help growers meet the complex agronomic challenges they face in 2021/22 – and beyond, says the AHDB.
New Group 3 biscuit wheat LG Prince combines group-leading UK treated yield (103% of control varieties), with good disease resistance, though the lower specific weight of 74.8 kg/hl may not suit everyone.
Stablemate from Limagrain, LG Illuminate, is just behind on UK treated yield (102%) and offers better specific weight, at 76.6 kg/hl, and a good
disease package. Its earlier maturity (+1), good northern yield and distilling potential may attract northern growers.
LG Quasar offers a similar package to LG Illuminate, with slightly lower quality, while LG Astronomer, though a little behind on yield, has a very good disease-resistance package, including a septoria tritici rating of 7.4, combined with a specific weight of 77.8 kg/hl. However, a mildew rating of 4 and North yield of 98% may limit its appeal.
The last of the new biscuit wheats is Merit from Elsoms – recommended for the East. Its yield in the East is especially good and a Hagberg Falling Number of 255 and specific weight of 76.5 kg/hl will prove attractive. Its disease-resistance package is only let down by a mildew rating of 3. All new soft Group 3s have resistance to orange wheat blossom midge.
The other new winter wheats also have interesting stories.
They include KWS Cranium (hard Group 4), which has good UK treated yield (104%), a reasonable disease-resistance package and quality, with a Hagberg Falling Number of 277 and specific weight of 75.4kg/hl.
But it is its late-sown yield (sown after 1 November) of 108% of controls that stands out. Although based on a more limited data set, it will pique the interest of many growers, especially those with one eye on blackgrass control.
The other new hard Group 4 feed wheat is RAGT Wolverine – first to
be awarded the new specialist BYDV-resistant category. But its yield is
a little behind the leading feed varieties, and ratings for septoria (5.3) and yellow rust (5) may put off some growers.
The final new winter wheat is the soft Group 4 variety Swallow, with recommendation for the North region. Limited data reveals it has a relatively early and good yield, which will appeal to northern growers.
But its main talking point is that it has been rated good for distilling, with consistent performance over the last three years – comfortably outperforming all other varieties in 2020 distilling tests.
Winter oilseed rape
The five new winter oilseed rape varieties are all hybrids. With UK recommendation, LG Aviron equals the top-yielding variety in the East/West region at 109% of control gross output.
Aviron also has a good northern yield at 105%, making it the second-highest yielding variety in the North. It also features good disease resistance, including to Turnip yellows virus (TuYV), in addition to pod-shatter resistance.
LG Antigua is recommended for the East/West region and equals the East/West yield of LG Aviron (109%). It also has good disease resistance (including TuYV) and pod-shatter resistance.
Also recommended for the East/West region, DK Expectation, from Bayer, has a gross output of 107%. Its good disease package includes a resistance rating of 8 for stem canker, as well as TuYV resistance and pod-shatter resistance.
A further East/West recommendation is Respect, from LS Plant Breeding, with a gross output of 106% and a stem canker resistance score of 8. However, it lacks pod-shatter and TuYV resistance.
The final addition is herbicide-tolerant variety DK Imprint CL, from Bayer, with UK recommendation. It has an East/West gross output of 95% and North gross output of 91%. Once again, stem canker resistance is good (rating of 8) and it features pod-shatter resistance. The variety has a light leaf spot rating of 6 but does not have TuYV resistance.
The only new spring barley variety on test for brewing, Skyway from Agrii, offers a significant yield improvement over the market leaders, with the UK treated yield of 106% of controls, with a similar yield in the East and 108% in the West.
Specific weight is very good at 68.7 kg/hl. Although data is limited, good disease resistance is suggested by its untreated yield of 96%. As with all malting varieties, the success of Skyway will depend on its commercial malting qualities. Farmers should speak to merchants before drilling to help establish market potential.
The single sfeed variety added is Cadiz from Senova, with recommendation for the East and West regions – with treated yields of 105% and 106%, respectively (based on limited data). Its untreated yield of 94% suggests good disease resistance. Specific weight is good at 67.4 kg/hl.
Three new two-row feed barley varieties all sport UK treated yields of 106% of controls. KWS Tardis has a specific weight of 69.1 kg/hl, with a good disease package and untreated yield.
Bolton, from Elsoms Ackermann, also has a good specific weight (68.6 kg/hl) and disease package. Bordeaux, from Senova, has a very good specific weight of 69.9 kg/hl. Although it comes with a reasonable disease package, a disease rating of 4 for rhynchosporium and net blotch might deter growers in wetter regions.
Two new six-row hybrid feed varieties from Syngenta show improved disease resistance and good yields. SY Kingston has a treated UK yield of 107%, excellent specific weight of 69.7 kg/hl, a good disease package and an untreated yield of 88%. SY Thunderbolt, also with 107% UK treated yield, has a specific weight of 69.6 kg/hl, a good disease-resistance package and an untreated yield of 88%. Both varieties are also relatively early maturing (-1).
