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 = 3100 Crop Heat Units or more.

3 sww = soft white winter, srw = soft red 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.
