The nature and magnitude of genetic divergence assessed in 32 genotypes of cowpea using Mahalanobi's D1 value, indicated considerable diversity In the material studied. The population was grouped Into 6 clusters, cluster IV had the maximum number of genotypes. The intra and inter cluster average of values indicated maximum statical distance between cluster I and V followed by III and V. The geographical diversity was not related to genetic diversity. Single plant yield, harvest index and earliness in flowering contributed considerably and accounted to 80% of total divergence.
