ABSTRACT
Combining ability for seed yield and its component traits in sesame was studied using line x tester mating design involving 8 lines and 5 testers. Analysis of variance for combining ability revealed that the mean squares due to lines were significant for all the characters, while for testers were significant for all the characters except number of seeds per capsule and the mean squares for lines x testers interaction were also significant for all the characters except plant height and oil content. The analysis for combining ability revealed significant mean sum of squares of both general combining ability (GCA) and specific combining ability (SCA) for all the characters which indicated the presence of both additive and non-additive gene actions.The lines IC 96128, TC 66 and DPI 1484 and the testers Guj.Til-4 and Guj.Til-3 displayed high gca effect and good per se performance for seed yield per plant and some desirable traits like plant height, height to first capsule, number of branches per plant, number of internodes per plant, length of capsule, width of capsule, number of capsules per plant, number of seeds per capsule and 1000-seed weight. The crosses RT 33 x Guj.Til-10, LIMDI 9 x Guj.Til-1 and TC 66 x Guj.Til-2 displayed high sca effects for seed yield per plant and important yield components.
Key words: Combining ability, GCA and SCA effects, Gene action, Sesame.
