Abstract:

Twenty eight cowpea entries of Agricultural Research Station, Virinjipuram were evaluated for yield and its components during two seasons Kharif 2014 and Rabi 2015. Wide range of variability was observed for various characters. Considerable amount of phenotypic and genotypic variability was observed for seed yield and component characters pods per plant and clusters per plant. The result indicated that the selected cowpea genotypes has shown mean value for 50% flowering was 45.00 days with total Days 7 4.50 for full maturity. The plant height was 73.27 cm with 16.77 no. of pods per plant. In addition 5.42 no. of cluster per plant with 13.50 seeds per pod, 5.84 g of 100 seed weight and 5.59 g of single plant yield. High heritability and low genetic advance as percentage of mean were recorded for days to 50% flowering, days to maturity and plant height suggesting that selection based on these characters could be effective. The character association studies indicated that selection based on days to 50% flowering, days to maturity, pods per plant, seeds per pod and 100 seed weight along with a medium plant height could useful for improving the yield in cowpea.
