Abstract
The studies of genetic divergence among 35 genotypes of pumpkin were carried out by using Mahalanobis D2 statistics. The research was conducted at main experiment Station of Department of Vegetable Science, Acharya Narendra Deva University of Agriculture & Technology, (Narendra Nagar), Kumarganj, Ayodhya, U.P.The experiment was conducted in Randomized Block Design with three replications. The wide range of divergence among the traits during 2021(kharif season). The clustering pattern of the 35 genotypes was grouped into 6 different non-overlapping clusters. Cluster I (26), II (4) and III (2) had same genotypes number as well as cluster IV (1), V (1) and VI (1). The minimum intra-cluster distance was found for 0.00 (cluster VI) and maximum was recorded for 220.05 (cluster III). The inter cluster values between cluster I to IV (1100.17), V to VI (657.01), II to IV (1294.53), III to VI (1069.11) and IV to VI (1879.65) were very high.
