ABSTRACT
Six parents and their 15 F2s of sesame were evaluated during summer 2013 for genetic variability in respect of fourteen quantitative characters. The analysis of variance for experimental design revealed that the mean squares due to genotypes were significant for all the fourteen characters studied. High GCV and PCV were observed for number of capsules per leaf axil, height to first capsule and seed yield per plant. High heritability and genetic advance as percentage of mean was observed for seed yield per plant, height to first capsule and number of capsules per leaf axil. Seed yield per plant showed significant and positive association with days to 50% flowering, plant height, number of branches per plant, number of internodes per plant, number of capsules per plant and 1000-seed weight. The path coefficient analysis indicated that the highest positive direct as well as appreciable indirect influences were exerted by the number of capsules per plant followed by plant height, number of internodes per plant and 1000-seed weight.
Key words :
