Cowpea [Vigna unguiculata (L.) Walp] is an important protein rich pulse crop produced globally, with high nutritional and economic value. Estimation of the genetic variation is key to any crop improvement program. The findings reported here would serve cowpea research and breeding programs including germplasm management, selection of appropriate genotypes to generate new breeding materials for cultivar improvement. These traits showed variability for biological yield per plant, plant height, seed yield per plant, days to maturity, pod/plant, pod length, peduncle length, days to 50 % flowering, seeds /pod, seed index, terminal leaf length, cluster/plant, no. of main branches, fresh pod weight, harvest index, terminal leaf width, no. of node on main stem, pod/cluster and no. of pods per peduncle. The traits with high magnitude of variability can be manipulates for its improvement. High heritability with high genetic advance was recorded for plant height followed by peduncle length, biological yield per plant, pod/plant, pod length, seed yield per plant, days to maturity, days to 50% heading, days to 50 % flowering, seeds /pod, seed index, no. of main branches, terminal leaf length, terminal leaf width, cluster/plant and fresh pod weight.
