1 Varieties are listed from earliest to latest heading date.
2 North 2002 includes Crookston and Stephen; 2 yr. includes 2001 and 2002 Crookston and Stephen plus 2001
Roseau; 3 yr. includes 2000, 2001, and 2002 Crookston and Stephen and 2000 and 2001 Roseau.
3 Mean of Lamberton, Morris, St. Paul, and Waseca.
4 Results of the Red River Valley On Farm Yield Trials.
5 Mean is calculated using all entries in the respective trial,including experimental lines. Therefore, the
average yield of varieties within a column may be greater or less than 100%.
