Interpretive Summary: US wheat breeders rely on the direction of US Wheat Associates for quality targets in the international marketplace. US Wheat bases their soft red wheat targets on the results of the Overseas Varietal Analysis produced by the Soft Wheat Quality Laboratory. Our results suggest that current targets should reflect divergent quality characteristics for users requesting high protein (10% to 12%) soft grain and users requesting low protein soft grain (8% to 10% grain protein).

Technical Abstract: The 2008 U.S. Wheat Associates Overseas Varietal Analysis evaluated ten soft red winter wheat varieties DK 9577, USG 3665, and USG 3350 from Arkansas, Jamestown, Tribute, and USG 3555 from Virginia, Branson, Magnolia, and Coker 9553 from North Carolina, and Bess from Missouri. Samples were evaluated by cooperating milling companies in the Dominican Republic, Mexico, South America, and Asia. Cooperators ranked variety and control flours from 1 to 11 (1=best). DK 9577 from Arkansas was the variety with the lowest (best) ranking in both the 8 variety and 10 variety set. Magnolia and Coker 9553 were the next most preferred varieties due to their good performance in cakes and south Asian steam breads. However, the Magnolia and Coker 9553 samples were not preferred in steam breads made by Chinese cooperators, who evaluated the full 10 variety set. As a result, Magnolia and Coker 9553 ranked near the bottom in the smaller set of evaluations that included all ten varieties. This highlights the diversity of preferences across customers, even within a region. USG 3665 was evaluated by a subset of the cooperators and in those evaluations performed similar to DK 9577. Similarly, USG 3350 was evaluated by a subset of the cooperators and was similar in performance to Bess or Jamestown.
