Genetic Variability in Cowpea (Vigna unguiculata (L.) Walp.) at Chhattisgarh Plains

Study on twenty two genotypes of cowpea (Vigna unguiculata (L.) Walp.) revealed significant differences among the genotypes for all the characters except for number of branches per plant, number of pods per plant and number of clusters per plant. The character seed yield per plot registered the highest magnitude of GCV (75.702) and PCV(78.275). The highest heritability estimate was recorded for the characters days to 50% flowering (99.89%) followed by hydration capacity (99.74%), days to maturity (99.63%), 100 seed weight (99.34%), seed volume (99.19%), swelling capacity (98.15%), swelling index (96.09%), seed density (94.02%), seed yield per plot (93.54%), hydration index (82.48%) and pod length (76.94%). However, among them only days to maturity, seed volume, swelling capacity, swelling index and seed yield per plot were having high genetic advance.
