Eleven cowpea genotypes were evaluated and significant genotypic effects for most of the traits studied. Number of pods/plants, pod, seed and dry fodder yields were high for phenotypic and genotypic coefficients of variation. High heritability values were recorded for number of pods/plant, 100 seed weight and dry fodder yield. Genetic advance was high for seed, pod and dry fodder yield indicating that the traits could be improved through selection. All traits had high genetic advance as per cent of mean except days to 50% flowering and number of seeds/pods. Dry fodder yield alone had combined high genetic advance and heritability values indicating that this trait has high selection value and considered important in cowpea improvement. IT99K-494-6 and IT98k-573-2-1 that were high for seed and pod yield; and dry fodder yield respectively, may be considered for further improvement.
