The current investigation was carried out on morphological evaluation of cowpea (Vigna unguiculata L. (Walp.) genotypes. Fifty genotypes were evaluated in a randomized block design with two replications at Central Experiment Station, Wakavali during Rabi 2022–23. ANOVA revealed highly significant differences among the 50 cowpea genotypes for all the traits studied, indicating the presence of sufficient genetic variability in the germplasm. Phenotypic coefficient of variation exceeded genotypic variation for all traits except the number of branches per plant. High estimates of heritability coupled with high genetic advance were observed for the traits viz., days to first flower initiation, days to 50% flowering, days to maturity, plant height, pod length, biological yield per plant and harvest index which indicates that additive gene action is involved and that selection will be effective in improving these traits. On the other hand, the characters number of primary branches per plant, number of seeds per pod, test weight, number of pods per plant, and grain yield per plant exhibited non-additive gene action, making selection ineffective.
