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.
