An investigation on evaluation of ridge gourd germplasm was carried out at College Orchard, Department of Vegetable Crops, Horticulture College and Research Institute, TNAU, Coimbatore. Totally thirty five ridge gourd genotypes were grouped into five clusters based on D2 values, which exhibited no association between geographical and genetic divergence. The intra-cluster distance was maximum for cluster III (167.41) and minimum for cluster V (0). The maximum distance at inter-cluster level was between cluster II and cluster V (535.54) followed by clusters III and II (195.34) which may serve as a potential genotypes for hybridization programme. On the basis of mean performance of different clusters, genotypes having better performance for days taken for first female flower appearance, highest female flower number per vine, narrow sex ratio, fruit length, days taken for first harvest, fruit weight, lowest crude fibre content, highest carbohydrate content and protein content were observed in cluster V. Genotypes having vine length, fruit girth, less seeds number per fruit and more hundred seed weight were recorded in cluster II. The genotypes of the cluster III were grouped for high fruit flesh thickness, fruits number per vine and fruit yield per vine which could be utilized as donor parents for respective traits in hybridization programme for enhancing the yield of other accessions grouped in a cluster in F1s and could be fixed by transgressive segregants followed by continued selection in advance generations which may lead to development of high yielding varieties with desired component characters.
