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 Cultivar yield ranking may vary from year to year. Decisions are therefore best made using data with the greatest number of years
³ Rust races have overcome genetic resistance in the past 4 years, with some varieties being significantly impacted.
