摘要：
The genetic diversity among ten Indian cultivars of cowpea was analyzed using 18 sets of RAPD markers. A total of 181 bands with an average of 15 bands per primer were obtained. Out of 181 bands, 148 showed polymorphism (81.7%). The variation in genetic diversity among these cultivars ranged from 0.1742 to 0.4054. Cluster analysis based on Jaccard's similarity coefficient using UPGMA with high bootstrap values revealed two distinct clusters I and II comprised of two and seven cultivars, respectively. Cluster II was further differentiated into various subclusters. Cultivar IC-9883 was found to be unique based on its altogether distinct position in the dendrogram and two-dimensional space projections.
