Genetic variability studies for quantitative traits in germplasm collections of sesame (Sesamum indicum L.).



One hundred and thirty one sesame genotypes were evaluated during kharif 2014 for genetic variability andother related parameters in respect of thirteen quantitative characters. Analysis of variance revealed highly significantdifferences among genotypes for all the thirteen characters studied. High genotypic coefficient of variation (GCV) andphenotypic coefficient of variation (PCV) were observed for seed yield per plant followed by number of capsules perplant, number of capsules on the main stem and number seeds per capsules while it was moderate for plant height, plantheight to first capsule, number of branches per plant, capsule breadth, 1000 seed weight. On the other hand, oil content,days to 50 per cent flowering, day to maturity and capsule length showed low genotypic and phenotypic coefficient ofvariation. High heritability and genetic advance as per cent mean was observed for seed yield per plant, number of capsuleson main stem, number of capsules per plant, plant height and number of seeds per capsule where as moderate heritabilitywith high genetic advance as per cent over mean was observed for plant height to first capsule and number of branches perplant. Characters such as days to 50 per cent flowering, days to maturity, 1000 seed weight and oil content showed highheritability and low genetic advance as per cent over mean. Moderate heritability with moderate genetic advance as per centover mean for capsule breadth and moderate heritability with low genetic advance as per cent over mean for capsule lengthwas observed.
