Forty ridge gourd genotypes of Indian origin were evaluated for agro-morphologic traits to assess geographic patterns of phenotypic diversity and to identify whether there are specific areas of high diversity for particular traits. Fifteen quantitative characters were taken into consideration. Cluster analysis was used for grouping of genotypes and grouped into six clusters. Cluster I had maximum (10) and cluster V had the minimum number (1) of genotypes. Highest (54.518) inter cluster distance was observed between cluster IV and VI and lowest (12.310) between cluster I and II. Cluster VI (D² = 24.606) has exhibited highest intra cluster distance and lowest was observed in cluster I (D² = 7.885). Days to Ist staminate flower, number of fruit per plant and days to first fruit harvest contributed maximum towards divergence. Genetic divergence among 40 genotypes revealed that the genotypes CHFRG10 and CHFRG22 from cluster IV, CHFRG 28 from cluster II and CHFRG 30 from cluster I were found to be superior for most of the yield components and fruit quality traits.
