Genetic variability parameters were estimated in F2 and F3 populations of two crosses viz., Dapoli Safed x GC 10 and Manjarkheda local x G 1 of cowpea. In both the crosses magnitude of PCV, GCV, heritability and genetic advance values higher in F3 as compared to F2 population. Number of pods per plant, biomass at harvest, days to maturity, number of seeds per pod, pod length, 100-seed weight and seed yield per plant recorded higher GCV, PCV, heritability and genetic advances, indicating the prevalence of additive gene action in the control of these characters and simple selection helps in development of high yielding cowpea genotypes.
