Summary

  • 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.

SY INSITOR

  • 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.
