Abstract
Thirty cowpea genotypes were investigated to analyse the genetic divergence for twelve characters. These genotypes were clustered into 8 distinct groups using Mahalanobis D2 statistic and Tocher's method. Cluster I and cluster II were the largest comprised of 12 genotypes each. Cluster III, IV, V, VI, VII and VIII were monogenotypic indicating wide diversity from the rest and also from each other. The maximum intra cluster D2 value was observed within cluster II followed by cluster I suggesting that genotypes present in these clusters might have different genetical constitution. The highest inter cluster distance was registered between cluster II and cluster III followed by cluster II and cluster V and cluster II and cluster IV indicating wide divergence among these clusters. The crossing among the genotypes of these divergent clusters could be used in hybrid development programme of cowpea.
