Abstract: Genetic variation is a tool improving yield, wider adaptation, selection of parents for hybridization, desirable quality, pest and disease resistance. This study was planned to investigate Phenotypic diversity of groundnut genotypes based on cluster analysis. The crop was sown during 2015 growing season in Ethiopia.The result of cluster analysis based on average linkage of 16 groundnut genotypes assessed for 12 agromorphological traits was shown that Baha Jidu, Shulamith, Oldhale (local variety) and Baha gudo genotypes were found to be divergent while the most similar genotypes were NC-343 and Roba belonging to cluster I; followed by Tole-1 and Tole-2 (cluster 2), Fetene and Werer 961(cluster7).The cluster mean analysis, for agromorphological traits has shown that genotypes in clusters 1, 2, 5, 6, 9 & 10 including NC-343, Roba, Manipeter, Werer-962, Tole-1, Tole-2, Behajidu, shulamith, Fetene, Werer-961 and Beha gudo can be used as parents in hybridization program for grain yield improvement.
