Intrastate, Advanced Yield, and Preliminary Winter Wheat Variety Performance Trials (2001)

Abstract

This report evaluates agronomic performance of new experimental lines and existing winter wheat varieties in Central Montana. Yields from the Interstate Nursery ranged from 38.3 to 54.4 bu/a with the average equal to 47.2 bu/a. Test weights were lower than average at 57.6 lbs/bu and grain proteins averaged 15.4 percent. Yields of grain varieties grown in the Advanced Yield Winter Wheat Nursery ranged from 41.7 to 57.4 bu/a with the average being 47.2 bu/a. Test weights were below average at 59.5 lbs/bu and grain protein averaged 15.4 percent. Grain yields in the preliminary nurseries ranged from 36.7 to 59.5 bu/a. Yields averaged 47.9 bu/a in the Preliminary A nursery and test weights were below average at 57.6 lbs/bu. Grain yields in the Preliminary B nursery averaged 51.4 bu/a and test weights were average at 60.1 lbs/bu. Soil moisture at seeding time was good and urea was broadcast in early September. Winter survival rates averaged 78 to 84 percent and total annual precipitation of 10.6 inches resulted in lower than normal yields. Lower than average test weights were accompanied by higher than average grain protein levels.
