The Genomic-DNA of five wild accessions (TVnu-59, TVnu-561, TVnu-563, TVnu-1148 and TVnu-1395) of Cowpea (Vigna species) using Un-weighted Pair Group Method of Arithmetic Means (UPGMA) was carried out at African Bioscience Laboratory, Ibadan, Oyo State, Nigeria. The samples of the five wild accessions (TVnu-561, TVnu-563, TVnu1148, TVnu-1395 and TVnu-59)were collected using molecular kits and analyzed using Single Nucleotide Polymorphism (SNP) marker.SNP generated a moderate level of polymorphism and revealed existence of similar genetic diversity among four (TVnu-561, TVnu-563, TVnu1148 and TVnu-1395) out of the five wild accessions. The three level sequences of the four wild accessions showed that two (TVnu-561 andTVnu-1395) were 40% monomorphic and three (TVnu-563, TVnu-1148 and TVnu-1395) were 60% polymorphic. However, TVnu-1395 demonstrated both monomorphism and polymorphism, a distinct character that showed its slightly similar genetic diversity with others. The Dendogram revealed the three wild accessions (TVnu-561, TVnu-563 and TVnu11480) that clustered togethershowed high degree of similar genetic diversity, formed a sub-cluster with in the one accession(TVnu-1395) with slightly similar genetic diversity. Clustering ranged from 1%-20%.TVnu-1395 which had the highest yielding characters with identified slightly genetic variations should be used to improve the others as these will enhance desirable traits such as yield.
