The sesame germplasm consisting of thirty three accessions were assessed for the extent of variability, degree and direction of character association among yield and its contributing traits and the direct and indirect effects of various components on yield. Analysis of variance showed significant differences among the genotypes for almost all the characters studied. High and moderate phenotypic and genotypic coefficients of variation (PCV and GCV) were noticed for most of the yield contributing characters. Highest and lowest PCV and GCV were recorded for number of capsules per unit length and 1000-seed weight respectively. High estimates of heritability coupled with high to moderate genetic advance as per cent over mean was recorded for all the yield associated traits except for days to maturity, oil content and 1000-seed weight. Yield had positive and significant association with the yield contributing characters such as plant height, number of primary branches, number of capsules per plant, length of capsule and number of seeds per capsule, signifying that selection based on these characters may improve yield. The highest genotypic and phenotypic correlation with yield was observed for number of capsules per plant. Path analysis revealed that number of capsules per plant had the highest positive direct effect on seed yield per plant followed by number of seeds per capsule. Number of primary branches per plant and days to maturity had the maximum positive indirect effect on seed yield per plant through number of capsules per plant.
