One hundred fifty one Sesame genotypes were evaluated during Kharif -2006 for genetic diversity in respect of nine quantitative characters. Analysis of variance revealed significant difference among genotypes for all the nine character studied. High GCV and PCV were observed for seed yield/plant, number of capsules/plant, number of primary branches/plant, number seeds/capsule and plant height. High heritability and genetic advance as per cent mean was observed for seed yield, number of primary branches/plant, number capsules/plant, number of seeds/capsule, plant height and days to 50% flowering. Seed/plant showed significant and positive association with number of primary branches/plant, number of seeds/capsule and capsule length. Path co-efficient analysis revealed maximum positive direct effect of number of capsules on seed yield followed by capsule length and plant height.
