Abstract
The experiment was conducted during the Rabi season of experimental year at Botanical Research Field in Rajshahi University. A total of 48 potato genotypes were evaluated for 6 quantitative traits in RCBD with 3 replications. Genetic divergence using Mahalanobis D2 techniques was studied for yield contributing traits. These genotypes were grouped into 6 clusters. Cluster IV showed maximum divergence with 12 genotypes followed by cluster III having 10 genotypes. The inter-cluster distance was higher than intra-cluster distances suggesting wider genetic diversity among the genotypes of different groups. The highest intra-cluster value was the maximum in cluster III (3.884) and minimum in cluster IV (1.012). The highest inter-cluster distance was in between cluster I and III (√D2 =11.847) indicating maximum exploitation of heterosis on hybridization. The maximum and minimum divergence was revealed between cluster I with III and cluster I with IV, respectively. In conclusion, according to cluster mean and principal component analysis cluster IV and cluster VI contained the best genotypes for most of the characters and could be used as parents in crossing program targeted at developing process type genotypes.
