Factor Protein into Spring Wheat Variety
Performance
AgriPro Wheat spring wheat breeder Joe Smith believes that protein premiums or discounts should be factored into income potential when selecting varieties. “In some years, yield is king and
in others, protein really pays off. The problem is, growers don’t know what will happen.” He advises producers to plant multiple varieties to help capture differences in yield, protein, disease
resistance, and maturity.
In the following table, Smith compares the three-year performance of leading private and public spring wheat varieties by economic return, using the 10-year average premium for wheat protein
at Minneapolis and a Sept. local cash grain price of $3.40 for 14% protein. Factors that have influenced this information include the overall lower protein of 2003-04 and the leaf disease and scab pressure in
2005.
Sites in this study include Valley City, Argusville, Park River, and Maddock in ND, and Breckenridge and Crookston in MN. Individual location data at AgriPro’s 15 research sites is
available at www.agriprowheat.com.
