Crop Background
***************
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 scab epidemics.
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. Scab evaluations provide severity ratings, based on visual
spread of the disease on the spike, and tolerance scores, which reflect the
variety's ability to maintain plump seed. These ratings should be
considered together 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.
