The genetic parameters viz.. genotypic and phenotypic variations, genotypic and phe- notypic coefficient of variation, heritability and genetic advance as percentage of mean were assessed from nine varieties of sesamum. Genotype x environment interaction was not significant for height up to first capsule, number of branches, number of capsule on main stem, number of capsule on branches and number of capsule per plant. The genetic coefficient of variability for number of branches was consistant at all environments. Number of branches, number of capsule on branches, number of seeds per capsule and yield have high values for both heritability (56.4 to 95.4) and genetic advance (14.8 to 48.0) and indicated additize gene effects in these traits. Due importance might be given in selection programme for the traits number of branches, number of capsule, number of seeds par capsule and yield.
