An experiment was conducted on genetic variability, heritability and divergence in the fifteen genotypes of ridge gourd during 2019-2020 at the Horticulture Research Farm of Dept.of Horticulture, S. H. University of Agriculture, Technology and Sciences, Prayagraj. The observations were recorded on various growth and yield attribute characters. The results from the present investigation revealed that on the basis of performance of 15 genotypes of ridge gourd, Jaipur long SPL (23343.07) genotype was found superior in terms of yield (kg/ha) and fruit weight large amount of variability existed in the genotypes for selection. The highest GCV were recorded for fruit length, fruit weight, fruit yield per plant, fruit yield per ha. The highest PCV were recorded for fruit length, fruit weight, fruit yield per plant, fruit yield per ha, no. of fruits per plant. The heritability estimates were found to be high (more than 60%) for fruit length, rind thickness, flesh thickness and fruit weight. genotypic and phenotypic path coefficient revealed that highest direct positive effect on fruit yield per plant was exhibited by days to 50% flowering, days to last harvest, fruit length, fruit diameter, rind thickness, flesh thickness, number of fruit plant and fruit yield (kg/ha). vine length (cm) at 90 DAS, days to 50%, fruit weight (g). Clustering pattern indicated that cluster I is largest cluster comprising 11 out of 15 genotypes. The inter cluster distance was maximum between cluster II and III (208.38), cluster III and Cluster IV (130.16), and Cluster I and cluster II (108.69). The highest contribution in manifestation of genetic divergence was exhibited by fruit length (41.9), fruit yield per plant (22.86), flesh thickness (11.43), rind thickness (8.57), number of fruit per plant (6.67), fruit weight (g) (6.67) and fruit yield per ha (0.95). In other words, selection for these characters may be rewarding.
