VARIABILITY STUDIES IN HYBRID AND SEGREGATING POPULATIONS OF SESAME

Abstract

Variability parameters such as phenotypic and genotypic coefficients of variability, heritability and genetic advance expressed as percentage of mean were studied in the F1s and F2s of a 10 x 10 diallel set. Higher estimates of GCV coupled with high heritability and expected genetic advance were noted for seed yield per plant, seed weight. per capsule, height of branching, plant height and number of capsules per plant in both the generations. Selection criteria comprising these characters have been suggested for improvement in seed yield through phenotypic selection.
