Abstract: The present experiment entitled “Genetic variability and character association studies in F₃ generation of cowpea. (Vigna unguiculata (L.) Walp.)” was carried out for assessing the genetic variability, correlation and path analysis in F₃ population of forty five crosses of cowpea in Randomized Block Design with two replications. The character seed yield per plant had positive and highly significant correlation with number of pods per plant (0.8906), harvest index (0.8758), 100 seed weight (0.7123) and pod length (0.3114) at phenotypic level. Similarly at phenotypic level it showed negative nonsignificant correlation with days to 50% flowering (-0.0159) while, days to maturity (-0.3005) had negative significant correlation. Positive and highly significant correlation was reported between seed yield per plant and number of pods per plant (1.0080) followed by harvest index (0.8652), 100 seed weight (0.7685) at genotypic level. Genotypically negative highly significant correlation was reported with days to maturity (-0.4294) and negative nonsignificant correlation with days to 50% flowering (-0.0413).
