ABSTRACT
An attempt was made to estimates the GCA, SCA and nature of gene action in the sesame (Sesamum indicum L.) through L x T mating design pattern with three lines and seven testers for different ten quantitative and qualitative traits viz., days to 50% flowering, days to maturity, plant height, number of branches per plant, number of capsules per plant, capsule length, number of seeds per capsule, 1000 seed weight, oil content (%) and seed yield per plant were studied. Based on the GCA effects female parent BSG-8 was found to be a good general combiner for seed yield, plant height, number of branches per plant, number of capsules per plant and oil content (%). Similarly, another female parent BSG-15 was found to be a good general combiner for days to 50 % flowering, days to maturity, length of capsule, 1000 seed weight and oil content (%). Among male parents genotype IC-413193 was found to be a good general combiners for number of capsules per plant and seed yield per plant. Five cross combinations viz., BSG-8 x LT-7, BSG-12 x IC-413193, BSG-8 x IC-413214, BSG-8 x IC-413193 and BSG-15 x IC-413193 exhibited significantly maximum positive sca effects. Hence, recommended for yield improvement through heterosis breeding.
