The present experiment was carried out using 51 genotypes at Vegetable Research Centre of G. B. P. U. A & T., Pantnagar, during kharif season of 2019. Mahalanobis D2 statistics was worked out using 11 quantitative characters to assess the degree of genetic divergence. On the basis of value generated using Tocher’s method, 51 genotypes were grouped into six clusters. Cluster I is largest with 42 genotypes followed by clusterII and III with 3 genotypes and cluster IV, V and VI containing 1 genotype in each. Cluster IV exhibited highest cluster mean value for the fruit diameter (8.46), average fruit weight (82.27), yield per plant (1.03), marketable yield per plant (0.84) and total yield per hectare (22.67). Highest inter cluster distance was found between cluster II and V ( 1139.496) suggesting the genotypes belong to these clusters would produce the best heterosis effect and have more chances of generating the best recombinants. Cluster III having only 3 genotypes showed highest intra cluster distance ( 215.253) indicating the genotypes under the group possess higher degree of genetic variability. Percent contribution of characters towards the divergence showed that out of eleven characters, 60.79 % contribution came from the single character i.e. number of fruits per plant followed by fruit length (16.52 %).
