Abstract:
The present investigation was conducted to estimate the genetic variability, heritability, genetic advance, character association and path analysis in Forty five sesame genotypes for twelve yield and its contributing traits. Analysis of variance revealed significant differences among the genotypes for all the characters studied except days to maturity indicating the presence of sufficient variability in the experimental material. Higher magnitude of both Phenotypic and genotypic correlation coefficients were recorded for branches per plant, capsules per plant and seed yield per plant. High heritability coupled with high genetic advance as percent of mean was observed for branches per plant, capsules per plant, capsule length and seed yield per plant which indicated that these traits are governed by additive gene action. The characters days to 50% flowering, plant height, branches per plant, capsules per plant, seeds per capsule, test weight, harvest index and oil content showed significant and positive association with seed yield per plant. Therefore, selection for these characters may be useful in increasing seed yield in sesame. Path coefficient analysis at genotypic level indicated that plant height, branches per plant, harvest index and oil content had positive direct effects and significant positive correlation with seed yield per plant. Hence, the use of these traits in sesame improvement programme would increase the seed yield.
