The existence of Genetic variation is essential to plant breeding for increasing yield, wider adaptation, selection of parents for hybridization, desirable quality, and pest and disease resistance. That is why this study was planned to investigate genetic variability based on cluster analysis of groundnut cultivars based on morphoagronomic traits. The crop was sown during 2015 wet season across four locations in Ethiopia in RCBD.The cluster analysis based on average linkage (UPGMA) of 16 groundnut genotypes, measured for 12 agromorphological traits was shown that Bahajidu, Shulamith, Oldhale(local variety) and Bahagudo genotypes were found to be distinct 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(cluster 7).The cluster mean analysis, for agromorphological traits, has shown that genotypes in clusters 1, 2, 5, 6, 9 and 10 including NC-343, Roba, Manipeter, Werer-962, Tole-1, Tole-2, Behajidu, shulamith, Fetene, Werer-961 and Behagudo can be used as parents in hybridization program for grain yield improvement.
