Abstract:
The study was conducted with objective to know the general and specific combining ability effects in F₁ and F₂ generations of hybrids obtained through diallel mating of 10 parents excluding reciprocals. The present study revealed that the The parents Ashirwad and Vardan proved to be best general combiners for twelve characters namely, days to 50 % flowering, length of main raceme, leaf area index, number of secondary branches, days to maturity, plant height, number of siliquae per plant, number of seed per siliquae, 1000-seed weight and oil content in general most of the parents maintained their superiority in both the generations and produced comparable estimates of gca effects. MK (L) 13-306 × MK (L) 13-301, MK (L) 13-310 × MK (L) 13-308, MK (L) 13-307 × MK (L) 13-308, Ashirwad × MK (L) 13-301 and MK (L) 13-304 × MK (L) 13-303, MK (L) 13-306 × MK (L) 13-301 in both the generations had desirable significant sca effects which are indicative of the presence of additive x additive interaction effects.
