Quality Characteristics of Hard Red Winter Wheats Grown in the Hard Red Spring Wheat Region1

J. L. Helm, K. A. Gilles and R. L. Harrison2

One hundred and seventy-seven varieties and experimental lines of hard red winter wheat, grown in the hard red spring wheat region, were evaluated for milling and baking quality characteristics. The winter wheats were compared with six cmnmercial varieties of hard red spring wheat. The winter wheats were superior to the spring wheats in kernel weight, test weight, and whole kernel ash content but inferior in mixogram score, water absorption and loaf volume; and somewhat similar in the other characteristics evaluated. Simple correlation coefficients in all possible combinations among the 14 characteristics were evaluated. Sedimentation scores and mixogram scores were highly correlated, r = +0.80**. A few of the winter wheats approached the overall quality level of the spring wheat standard.

Key Words: mixogram curves • sedimentation score • protein content
