Fluorescence intensity, hardness, and protein data on whole wheat flours were analyzed using a discriminant function to classify wheats. Six classes and subclasses of wheat were represented in a set of 77 samples. When red wheats and durum were considered, a high correlation (r = -0.907) between hardness and fluorescence was obtained; however, when white wheats were included, the correlation dropped (r = -0.05). Discriminant analysis allowed separation of wheat into proper classes for 100% of durum, hard red spring, club, soft red winter, and soft white winter wheats; and for 94% of hard red winter wheat.
