1 Values differing by less than 3 within a column may not represent true differences in yield. Yield Indices are Heritability Adjusted Relative Values (HARV), which favour results from trial locations with high repeatability. For more information, see: Yan, W. Use of HARV in Variety Trial Summaries.
2 Area I: see map of areas on www.gocereals.ca/variety_trial.php.
3 sww = soft white winter, srw = soft red winter, hww = hard white winter, hrw = hard red winter.
4 Cultivar yield rankings may vary from year to year. Decisions are therefore best made using data with the greatest number of years.
Fungicide treatments included a T1 application of foliar fungicide at Zadoks Growth Stage 30 to 31, followed by a T3 application of fusarium fungicide during flowering.
The OCCC is thankful to the Grain Farmers of Ontario, BASF, Bayer and Syngenta for their financial support towards the intensive trials.
