摘要

A carmel seed coat colour mutant in yellow sarson (B. campestris var. yellow sarson ) was isolated in the strain VSIK 4 at 5u KR. It was high yielding, bold seeded with carmel seed coat colour (Chauhan and Kumar,1936). In order to study its inheritance, the mutant was crossed with yellow sarson strain NDYS 1 possessing yellow seed coat colour during 1986-87 and required generations were developed. The parents, F1,F2, BC1 and BC2 were grown during 1988-89. The Fl seeds were carmel in colour indicatingits dominance over yellow seed colour. The F2 generation segregated into 188 carmei seed'ed and 45 yellow seeded plants indicating monogenic dominant inheritance for this trait (X~2 = 4.01 at p = 0.05-0.02). Segregation pattern in BC2 generation also confirmed the mode of inheritance observed in F2 generation. Monogenic dominant gene action of drown seed colour over yellow seed colour has been reported by-Singh (1958).
