Aims: Cassava (Manihot esculentaCrantz)is a crop with largely unexplored and unexplained potentially valuable genetic variability. The knowledge and understanding of the extent of genetic variation ofcassava germplasm is important for conservation and improvement. Objective:The current study was to investigate the genetic divergenceof cassava mutants, hybrids and landraces using simple sequence repeat (SSR) markers. Methodology: Genetic diversity o f ten cassava genotypeswas determined using 14 SSR markers. Results:Findings from this study showed that the dendrogram based on UPGMA cluster analysis revealedthat SSR data indicated the existence of high divergence among the accessions . The cophenetic matrices obtained showed that SSR data marker type wasr = 0.91. Conclusion: The wider genetic diversity observed using SSR markers would be valuable for efficient management of germplasm and for effective utilization of materials in breeding programmes to produce hybrids of desirable characteristics. The extensive genetic diversity is Original ResearchArticle
