Abstract

Genotypic correlation coefficients and path-coefficient analysis were studied in 84 genotypes of sosome (Sesamum indicum L) under three environments. Grain yield per plant had significant positive correlation with number of effective branches per plant, number of capsules per plant, capsule length and number of seeds per 5 capsules over the environments studied. The magnitude of correlation coefficients, direct and indirect effects of various yield contributing traits differed from location to location suggesting considerable amount of genotype x environment interaction in the expression of various charactus. Path analysis revealed that number of capsules per plant was the most important component trait contributing to seed yield due to its positivo direct and indirect effect on seed yield in all the environ- ments under study.
