dc.description.abstractWide crosses of twelve different genotypes of cultivated cowpea Vigna unguiculata were made with a view to transferring useful genes to obtain hybrids with new traits that can be of immense contribution to the yield of cowpea in the world. The expected hybrids are intended to be used for mapping population for further cowpea breeding programs. A total of 102 attempts were made but only eight out of all the crosses were successful. Out of the eight successful crosses, only three were viable and germinated when planted. All the twelve genotypes studied were examined for their morphological characters which were later used to construct a dendrogram. The dendrogram showed that the genotype with accession number IT845-2246-4 is genetically more diverse compared to others. At 0.40 similarity coefficient, three clusters were formed. These clusters contain sub-clusters which vary from each other. However,at a very high similarity coefficient of about 0.72 there exist relationships between genotypes 2 and 8. A combination of the morphological and breeding works can be used to identify various kinds of genotype and as a reference point for further studiesen_US
