A field investigation was carried out with twenty four genotypes of wild melon to study the path analysis and diversity studies for different quantitative and qualitative characters. Path analysis studies revealed that significant positive association at genotypic level among the traits viz., leaf area (0.824), number of fruits per vine (1.364), fruit length (0.474), fruit diameter (1.259), cavity size (0.236), fruit flesh thickness (0.769), Total soluble solids (0.204) and vitamin C (0.152) had exhibited true association with direct effect on yield per plant. The direct selection for these traits would be rewarding for improvement in the total yield per plant. Genetic diversity was studied with same genotypes. The genotypes were grouped into eight clusters with irrespective of geographic divergence, indicating no parallelism between geographic and genetic diversity. The maximum number of genotypes (17) was found in cluster 1 with intra-cluster distance of (22.12). The maximum inter-cluster distance was observed between cluster III and cluster VIII (97.23). Hence, genotypes belonging to these clusters may be utilized for involving in hybridization program for crop improvement. The among 18 characters included for D2 analysis, vitamin C content (71.01%) followed by fruit flesh thickness (20.65%), fruit cavity size (3.99%) and leaf area (1.88%) contributed more for genetic divergence.
