Abstract:
Fifty one genotypes (36 crosses + 12 lines + 3 testers) of sesame were evaluated for seed yield and its components for different variability parameters and path coefficient analysis. Analysis of variance revealed significant differences among the genotypes for all the characters. The magnitude of phenotypic coefficient of variation (PCV) and genotypic coefficient of variation (GCV) was larger for number of internodes per plant, height to first capsule, number of branches per plant, number of capsules per plant, number of capsules per leaf axils and seed yield per plant. Genetic advance as percent of mean for seed yield per plant, number of internodes per plant, height to first capsule, number of branches per plant, number of capsules per plant and number of capsules per leaf axils were higher in sesame genotypes. Path coefficient analysis of fourteen yield contributing characters clearly indicated that number of capsules per plant showed the highest positive direct effect on seed yield followed by number of seeds per capsule, 1000-seed weight, plant height and length of capsule which indicated positive direct effects in descending order and other characters days to maturity, height to first capsule, number of branches per plant, width of capsule and oil content contributed indirectly towards seed yield in sesame.
