Abstract


Genetic diversity among 21 released varieties of cowpea [Vigna unguiculata (L.) Walp] was analysed using RAPD markers. A total of forty primers of two series (OPF01-20 and OPAG01-20) were used to screen the polymorphic primers and the profiles generated by three such primers were used for analysis. The genetic similarity co-efficients among genotypes varied between 0.44 to 0.82. Based on UPGMA and SAHN clustering cowpea genotypes grouped into two main clusters. Cluster II comprised of genotypes CO-7 and GC 3, while other nineteen genotypes were grouped under cluster I. However, the primers OPF 2, OPF 20 and OPAG15 were most polymorphic that can be used to fingerprint cowpea varieties
