Abstract

Thirty five sesame genotypes were evaluated for the estimation of heritability, correlation, path analysis and genetic divergence for twenty traits. High estimates of heritability were recorded for all characters. High heritability coupled with high genetic advance was recorded for characters capsule split before drying, retained seed weight, unattached and retained seed number. Seed yield showed a highly significant and positive correlation with branch number per plant, capsule number per plant, 1000-seed weight, unattached and retained seed number. The character potential seed weight contributed maximum towards genetic divergence. From the combined results of correlation coefficient and path analysis, it was observed that branch per plant; capsules per plant, 1000-seed weight, unattached and retained seed number are the major yield contributing characters to be given selection pressure for improving yield. Also the genotypes possessing combination of above characters should be used in a breeding program for obtaining desirable high yielding segregants.
