Abstract:

The characterization and variability analysis of cowpea genotypes provides valuable information about parental selection for strengthening the future breeding programme in cowpea. Eleven cowpea genotypes are used in investigation. Genetic parameters like range, mean, standard error, variance, standard deviation calculated among nine quantitative traits and five qualitative traits of cowpea. Phenotypic coefficient of variation values was relatively higher than the genotypic coefficient of variation for all the traits studied. High heritability with high genetic advance was reported in plant height, days to 50 percent flowering, days to first flower maturity, number of pods per plant and single pant yield. While high heritability with low genetic advance was noted in number of seeds per plant, pod length, number of branches per plant and 100 seed weight. In addition, proline analysis was conducted to isolate the drought resistant cowpea genotype. Among the eleven genotypes, VBN 3 is identified as the superior genotype for yield enhancement as well as drought tolerance.
