1 Indexed for each site and then averaged. Index = 100 x (variety yield/site yield). Values differing by less than 3 within a column may not represent true differences in yield. 2 Cultivar yield ranking may vary from year to year. Decisions are therefore best made using data with the greatest number of years Show more data...
