Seed-coat color genes in six commercial varieties of beans

Francis L. Smith

Hilgardia, 1961, vol. 31, issue 1

Abstract: Colored beans have a dominant pigmentation gene, P, which acts with a number of seed-coat color genes to give a vast array of seed-coat colors. If p is present in the homozygous state, the beans are white regardless of the color genes. Lamprecht, a Swedish worker, had a white-seeded line which had P. This P-white, he assumed, was colorless because it had none of the dominant color genes. Seed of a P-white, Line 214, was obtained from Lamprecht and was used in crosses with mottled, self-colored, and white-seeded commercial varieties. The genotypes of the F2 color segregants in these crosses were determined by studying the F3 progenies from each color type from each cross.
