Cowpea is one of the rarely utilized pulses with adequete protein content and good fodder value. In the present study, various species of cowpea are evaluated and characterized for advancing the germplasm to further breeding programmes. Genotypic coefficient of variation, heritability and genetic advance were assessed for 50 genotypes of cowpea which included Vigna unguiculata, Vigna catjang and Vigna sesquipedalis. Genotypes differed significantly for all characters studied. High heritability coupled with high genetic advance was observed for plant height, pod length, peduncle length, number of pods per plant and number of branches per plant. Number of cluster per plant had highly significant positive correlation with number of pods per plant. Days to 50% flowering significantly but negatively associated with peduncle length. Number of branches per plant showed significant positive correlation with number of cluster per plant. Number of seeds per pod exhibited significant positive correlation with 100 seed weight. Grain yield per plant exhibited significant positive correlation with number of clusters per plant and number of pods per plant. The study showed that number of seeds per pod was the reliable for effective selection in cowpea.
