Genetic variability in sesame (Sesamum indicum L.)

Abstract

Genetic parameters of variability and heritability of different characters were studied in four crosses of sesame. In the present study, variability parameters were observed in two crosses viz., Paiyur 1 x SVPR 1, F₂ of TMV 4 x SVPR 1 and their BC1F1s. High genotypic coefficient of variability and phenotypic coefficient of variability were observed for number of branches per plant, number of capsules per plant and seed yield per plant. High heritability along with high genetic advance as per cent of mean for number of branches per plant, number of capsules per plant and seed yield per plant will be useful for further breeding programme. Based on per se performance, heritability, genetic advance as per cent of mean, F₂ and BC₁F₁ of TMV 4 x SVPR 1 were considered as superior crosses. This cross can be subjected to selection programme to obtain high yielding segregants.
