Technical Abstract: Meeting customers' demands for quality is key to the short and long term health of the wheat industry in Washington. The USDA ARS Western Wheat Quality Laboratory (WWQL) has been working in close association with the Washington Wheat Commission and WSU to develop a system of scoring wheat varieties based on end-use quality. One of the primary products of this work is the "Preferred Wheat Varieties for Washington Based on End-Use Quality" pamphlet, which for the second year running is being widely distributed by John Burns at the WSU Variety Testing Program plot tours. To ensure a high level of confidence in the Quality Rankings that appear in that pamphlet, samples from multiple locations and at least three crop years are rigorously tested. Varieties that had attained their third year of evaluation were placed on the 2006 Preferred Variety list.
