dc.description.abstractThe present investigation was carried out with thirty three genotypes of cowpea entitled “GENETIC VARIABILITY AND CHARACTER ASSOCIATION STUDY IN COWPEA [Vigna unguiculata (L.) Walp.]” at Vegetable Research Farm of Dr. Rajendra Prasad Central Agricultural University, Pusa, Samastipur, Bihar in Randomised Block Design with three replications during mansoon season-2018. The materials comprised the thirty three genotypes of cowpea including the check “Kashi Unnati”. Most of the yield attributing characters had high heritability coupled with high genetic advance, indicating the preponderance of additive gene action, which will help to make selection in early generation. Seed germination percentage, peduncle length and average pod weight exhibited positive and significant association with direct and positive effect on pod yield per plant. Suggesting that selection on the basis of these traits could be effective for crop improvement. All the thirty three cowpea genotypes were classified into five clusters using Tocher method. The maximum inter cluster distance was recorded between cluster V and cluster III followed by cluster V and cluster II. Suggesting that to have the heterotic recombinants for the improvement of traits, genotypes from cluster V, cluster III and cluster II may be used in crossing programme as it is evident that high cluster mean value recorded for seed germination percentage and peduncle length having the positive and high direct effect on pod yield per plant.en_US
