Abstract
Economic yield attributing characters were studied in sesame for crop improvement for selecting high yielding genotypes. Path analyses were carried out to estimate the direct and indirect effects of the progenies of the cross Padma × JSLV 4 in sesamum yield components. High values for genotypic coefficient of variation (GCV) and phenotypic coefficient of variation (PCV) were recorded for number of branches per plant followed by seed oil content (%) and seed yield per plant (g). Number of capsules per plant in F2 and plant height at harvest in F3 recorded the highest magnitude of genetic advance. The number of capsules per plant had the highest positive direct effect on seed yield per plant indicating that one can rely upon this trait for selection of high yielding genotypes in segregating generations of sesamum.
Key words: Correlation, heritability, sesamum, variability.
