Independent assortment of seed color and hairy leaf genes in Brassica rapa L.

Abstract

Rahman, M. 2014. Independent assortment of seed color and hairy leaf genes in Brassica rapa L. Can. J. Plant Sci. 94: 615–620. A genetic study of seed color and hairy leaf in Brassica rapa was conducted in progeny originating from the brown-seeded, hairy leaf B. rapa subsp. chinensis line and the Bangladeshi B. rapa var. trilocularis line. A joint segregation of both traits was also examined in the F2 and backcross populations. Seed color segregated into brown, yellow–brown, and yellow, which suggests that digenic control of brown or yellow–brown color was dominant over yellow seed color. Hairy leaves were found to be under monogenic control, and hairy leaf was dominant over non-hairy leaf. The data show that genes controlling seed color and hairy leaf are inherited independently.
