Economic yield attributing characters were studied in sesame for crop improvement for selecting high yielding characters. Path analyses were carried out to estimate the direct and indirect effects of the cross AVT 3 × TC 25 in sesamum yield components. High values for genotypic coefficient of variation (GCV) and phenotypic coefficient of variation (PCV) was recorded for number of branches per plant followed by seed oil content (%) and seed yield per plant (g). The differences between GCV and PCV estimates were high indicating the role of environment in the character expression. Heritability estimates in broad sense were of high magnitude for number of branches per plant in F2. Seed oil content in F2 had higher values of genetic advance. Number of capsules per plant and seed oil content had high genetic advance as well as heritability indicating the fact that by making selection it is possible to make progress in the advanced generations.
