Abstract
Genetic divergence among 18 pumpkin genotypes was estimated using Mahalanobis’s D2statistic. Altogether four clusters were formed where cluster I contained the highest number of genotypes (8) and cluster II contained the lowest (1). The highest intra-cluster distance was observed for cluster I (0.831) and the lowest for cluster IV (0.651). The highest inter-cluster distance was observed between cluster I and II (24.346). Cluster II recorded the highest mean for fruit number/plant, TSS, fruit yield and minimum in cavity length and cavity diameter. Cluster III had the second highest mean for fruit diameter, fruit number/plant, individual fruit weight, fruit yield and the fewest number of days to 1st female flowering, earliness being a desirable trait. These crosses may produce new recombinants with desirable traits.
