The experimental material consisted of ten parental genotypes and their 45 F1s developed through half diallel mating design, was evaluated in Randomized Complete Block Design with three replications. The magnitude of both the estimates; σ2gca and σ2sca, potent ratio and predictability ratio revealed prominence of additive genetic variance for days to 50% flowering, days to 80% siliquae maturity, test weight and glucosinolate content while non-additive genetic variance preponded for plant height, number of siliquae per plant, seed yield per plant, harvesting index; and erucic acid content.The parents Pusa bold, Bio-902, NUDHYJ-3 and EC-287711 were good general combiners for seed yield and at least for two important yield attributing characters. The F1s Bio-902 x NUDHYJ-3, Pusa Bold x EC-287711, Pusa bold x GM-3,Bio-902 x TM-2 and Bio-902 x JM-3 were good specific combiners for seed yield and represented all the good general combiners parents except JM-3, suggesting major component of pseudo additive gene effect of non-additive gene effect.
