Studies on genetic variability parameters in sesame (Sesamum indicum L.)

Abstract

Thirty sesame genotypes (25 advanced lines and 5 released varieties) were evaluated during kharif 2018 for genetic variability and other related parameters in respect of ten quantitative characters. Analysis of variance revealed significant differences among genotypes for all the ten characters studied. High genotypic coefficient of variation (GCV) and phenotypic coefficient of variation (PCV) were observed for the number of capsules per plant while it was moderate for days to 50% flowering, plant height to first capsule, number of branches per plant. On the other hand, height of the main stem, capsule length, 1000 seed weight, days to maturity, oil content and seed yield per plant showed low genotypic and phenotypic coefficient of variation. High heritability and genetic advance as per cent mean was observed for days to 50 per cent flowering, number of branches per plant and plant height to first capsule where as high heritability with moderate genetic advance as per cent over mean was observed for height of the mainstem. Low heritability and genetic advance as per cent over mean observed capsule length, 1000 seed weight, days to maturity, oil content, and seed yield per plant.
