Abstract

Phenotypic and genotypic coefficients of variation, heritability (B. S) and genetic advance were assessed in 40 genotypes of sesamum (Sesamum indicum L.), the differences between the types were highly significant for all the nine characters studied, The heritability estimates for all the characters were high. Branch number, capsule number and seed yield recorded higher values of PCV, GCV, heritability (B. S.) and genetic advance as percent over mean. Selection based on these characters would be more useful in the improvement of this crop.
