Karnataka) during Rabi season of 2020 with 34 sponge gourd genotypes.Based on Mahalanobis D 2 statistics, genotypes were grouped into six clusters.Cluster I included the higher number of genotypes (24), cluster II had 4 genotypes and cluster V and VI had two genotypes each and remaining two clusters (III and IV) were monogenic groups containing single genotype each.Highest inter cluster distance (976.58) was recorded between the cluster cluster VI and cluster II, indicating the genetic makeup of the genotypes belonging to one cluster differed completely from the genotypes those included in another cluster.In hybridization programme, genotypes present in these clusters could be used as parents to obtain promising segregants.Among the different traits, average fruit weight (34.22%) contributed maximum to the diversity followed by number of fruits per vine (18.00%) and fruit yield per vine (12.30%).
