Hard red spring (HRS) wheat constitutes about 25% of the wheat crop in the United States and is exclusively grown in the Northern Plains states of MN, MT, ND and SD. HRS wheat is known to have high protein content and excellent milling and baking performance. Domestic and overseas buyers pay top dollar for HRS wheat because of its high quality and unique characteristics. This research investigated the overall ranking of HRS wheat cultivars that were milled on Quad. Jr, Quad. Sr, Buhler MLU-202, and MIAG-Multomat roller mills. A cultivar scoring system was developed that considered their milling, flour, dough, and bread-baking qualities. A cultivar scoring system was designed to rank wheat cultivars for scores between 1 and 10, 1 being “average” and 10 being “most desirable”. A total of twelve HRS wheat samples from 10 cultivars (Forefront, Elgin, Bolles, 817, Ingmar, Glenn, Dapps, Faller, Focus, and Prosper) were used in this study. Mill type and wheat cultivar had significant (P<0.001) effect on the milling, dough, and baking quality scores. Cultivar by mill type interaction did not appear to be so strong as to cause discrepancy in quality evaluation of wheat cultivars since ranking of twelve HRS cultivars was consistent for the overall quality score across different mill types. Based on the overall quality score Bolles, Glenn, and Ingmar cultivars were considered most desirable receiving overall scores of 7.1, 7.1, and 6.5, respectively. In contrast, Elgin, Focus, Forefront, and Prosper cultivars were considered to be average receiving overall scores of 6.0, 5.9, 5.8, and 5.5, respectively. The proposed overall wheat scoring system could assist farmers in selection of wheat cultivars considering the wheat end-use quality. Development of a comprehensive scoring system will also enable a more detailed scoring system for screening new lines for suitable end-use.
