The present investigation was carried out to obtain the information in relation to genetic variability, heritability, genetic advance, correlation and path coefficient for 12 characters involving 50 genotypes of Pigeonpea [Cajanus cajan (L.) Mill sp.].The highest GCV was recorded for secondary branches plant-1(76.19) followed by yield plant-1(45.46). Heritability in broad sense ranged from 52.0% (days to maturity) to 100% (secondary branches plant-1). High genetic advance was observed for secondary branches (156.60), yield plant-1(92.02), biological yield (87.61) and pods plant-1 (85.57) indicating the prevalence of additive gene action for inheritance of these traits. Correlation studies revealed that seed yield was positively and significantly correlated with biological yield plant-1, pods plant-1 and plant height. Path coefficient analysis showcased the traits with direct and indirect effect analysis based on seed yield plant-1, as a dependent variable, showed that significant for biological yield, pods plant-1, plant height and secondary branches plant-1. Both correlation and path analysis indicated that pods plant-1 and biological yield were the major indirect contributors to seed yield.
