The winter wheat varieties exceeding 5-year average in official results
(Official AHDB Harvest Results 10.09.21)
Data from 26 sites is providing a good indication of variety performance.
Yield of control varieties are just above the 5-yr average (+0.02 t/ha).
The value of proven varieties: 27/44 varieties have performed below their 5-year mean but all three Syngenta hard group 4 varieties have exceeded their 5-year average in 2021.
Average specific weight is the lowest it has been in the last 5 years with the trial mean at 75.4 kg/hl vs the 5-year mean of 77.04 kg/hl.
17 out of 44 varieties in trial have had an average specific weight of below 75 kg/hl in 2021. Despite the poor season, all 3 Syngenta hard group 4 varieties have performed above this.
Another exceptional year, delivering 107% of control means which places it as the highest yielding fully recommended variety this year.
SY INSITOR has performed consistently well across the trials network. The lowest recorded yield for SY INSITOR remains higher than all other varieties at 102% of control means.
SY INSITOR delivered good grain quality, in particular specific weight at 77.2 kg/hl despite the trial mean being down at 75.4 kg/hl.
Attractive combination of high yield and high specific weight make it a great option in low specific weight years, giving you the added security of hitting all contract specifications.
GLEAM doesn’t disappoint and is currently the highest yielding control variety at 105% of control means, and is currently the fourth highest yielding variety in trial year.
GLEAM has demonstrated its adaptability and has performed well at all sites (100%+ at all 26 sites), showing no limitations – an excellent choice in all regions.
GLEAM has performed well in both the main trials set and early drilled trials (105% CM).
A strong performance yet again from GRAHAM, really showing the value of proven varieties.
GRAHAM has delivered an average yield of 104% of the controls, excelling in the West again.
High untreated yields (114% CM), driven by good agronomics and in particular, it’s unique Septoria tritici resistance.
GRAHAM has also delivered reliable grain quality (2021 specific weight 76.5 kg/hl) despite the challenging conditions.
