Thirty-one genotypes, year and interaction (G×Y) items were well differentiated by the analysis of variance. Greater variability observed among the varieties was due to genetic causes according to genetic parameter study. The results also indicate that plant height, number of leaflets/compound leaf, leaf area, foliage coverage/plant, fresh weight/compound leaf, number of tuber/plant, single tuber weight/plant and tuber weight/plant exhibited high GA, high heritability as well as high GAM (% of mean), therefore, these characters might be advocated to improve the tuber yield by effective selection. Five different cluster might be included 31 genotypes according to cluster analysis and these cluster analysis comment that cluster II and III was far diverse from genotypes of the cluster I where as it was least diverse from the genotypes belonging to V and IV. Heterogeneous and homogeneous nature between and within groups were suggested for higher inter cluster distance than intra-cluster respectively. Considering all the characters, it might be suggested for developing high yielding varieties of potato through breeding programs using the genotypes of cluster I and II.
