Interpretive Summary: End-use quality of wheat grain is central to the breeding, selection, production, marketing, use, and value of varieties. The objective assessment of the end-use quality of individual wheat varieties and advance breeding lines in the U.S. often falls under the purview of the U.S.D.A. Agricultural Research Service working in close collaboration with public universities and private breeding companies. The Western Wheat Quality Laboratory (WWQL) in collaboration with the Washington State University (WSU) has provided objective and complete analysis of the end-use quality of cultivars and advanced breeding lines since 1997. This report summarizes the first 10 years of that program.

Technical Abstract: End-use quality of wheat grain is central to the breeding, selection, production, marketing, use, and value of varieties. The objective assessment of the end-use quality of individual wheat varieties and advance breeding lines in the U.S. often falls under the purview of the U.S.D.A. Agricultural Research Service working in close collaboration with public universities and private breeding companies. The Western Wheat Quality Laboratory (WWQL) in collaboration with the Washington State University (WSU) has provided objective and complete analysis of the end-use quality of cultivars and advanced breeding lines since 1997. This report summarizes the first 10 years of that program. Soft white cultivars and advanced breeding lines were grown in field plots according to winter or spring growth habit. End-use quality was analyzed via ANOVA and a 'Genotype,' 'Environment,' and error model. The data set contained over 1,200 individual plot/grain samples. Grain yield and grand mean was 6.3 mt/ha; grain protein was 10.0%. 'G' and 'E' ANOVA model R2's ranged from 0.68 (winter set, flour swelling volume) to 0.94 (winter set, grain yield). Most model fits were in the 0.7 to 0.9 range, indicating good fits even in the absence of a GxE interaction term.
