Abstract: The present investigation was conducted during the kharif season of 2018 to obtain the knowledge of nature and magnitude of genetic parameters and its utilization in development of superior varieties of pigeonpea [Cajanus cajan (L.) Millsp.]. The results indicated that the genotypes showed significant variability for all the traits studied. The moderate estimates of genotypic coefficient of variation (GCV) were observed for pods per plant, yield per plot, days to 50% flowering, test weight, pod length and days to maturity, while the traits branches per plant, seed per pod and plant height exhibited low estimates of GCV. High heritability accompanied along with high genetic gain was recorded for days to 50% flowering, days to 80% maturity, test weight and grain yield. Grain yield showed positive correlation with pods per plant and branches per plant. Path analysis revealed that pods per plant and branches per plant were the major component of grain yield. Over all study showed that selection may effective for the pods per plant, branches par plant, test weight, days to 50% flowering and days to 80% maturity for development of early maturing and high yielding genotypes in pigeonpea.
