MINNESOTA HARD RED SPRING WHEAT - 1995
R.H. Busch, USDA-ARS
****************************************************************
Recommendations for hard red spring wheat varieties are no longer
being made by Minnesota Agricultural Experiment Station
evaluators. The basis on which recommendations were made in the
past are no longer considered appropriate because of the severity
of the scab epidemics.
The scab epidemics in hard red spring wheat growing areas have
demonstrated the clear need to give greater weight to selecting
varieties for their tolerance to this devastating disease.
Consequently, only newly released varieties where reaction to
scab has not been well documented, and older varieties with scab
ratings better than susceptible, are tested and described. Those
varieties with seed available, but found to be susceptible are
2371, 2398, Bergen, Dalen, Gus, Krona, Minnpro, Norm, Prospect,
Sonja, Vance, and Wheaton.
Table 1 presents long term grain yield for varieties grown at
various locations in Minnesota. Other important agronomic,
disease and bread-making quality characteristics are in Table 2.
Scab evaluations provide seventy ratings, based on visual spread
of the disease on the spike, and tolerance scores, which reflect
the variety's ability to maintain plump seed. The accompanying
tables should be used in conjunction with each other to reduce
risk of loss. Use of more than one variety is also highly
recommended to reduce risk.
Variety descriptions do not provide information on scab
resistance. Table information should be used. Varieties are
listed in maturity order.
