Investigation on Genetic Variability, Heritability, Correlation Studies in Cowpea (Vigna unguiculata L.)

The field experiment was conducted during rabi season of 2022 at horticulture research farm, department of horticulture, naini agriculture institute, shuats, to study on genetic variability, heritability, correlation studies in cowpea (Vigna unguiculata L.) were estimated among 14 cowpea genotypes for 19 qualitative traits. The High estimate of GCV along with high heritability coupled with high genetic advance as percent of mean was recorded for number of seeds per plant, seed weight per plant, green pod yield per plant and pod yield per hectare. While moderate estimate of GCV along with high heritability coupled with high genetic advance as percent of mean was recorded for pod length, number of peduncles per plant, number of pods per peduncle, plant height at both flowering and maturity stage.
