Abstract

                                Fifty genotypes of Sesamum indicum belonging to various geographical background were grown in a field experiment during 1986 and five components, namely, root weight, stem wight, leaf weight, capsule weight and seed yield were recorded. Data subjected to heritability and correlation studies revealed that the highest genotypic coefficient of variability, heritability and genetic advance were observed for the component stem weight indicating additive gene action. Lower heritability and genetic advance as per cent of mean were recorded for root weight and seed yield indicating that variation in these characters was governed more by environment rather than the heritable genetic component. Stem weight had high genotypic correlation to seed yield followed by capsule weight, root weight and leaf weight respectively.
