A study was carried out during the three consecutive years during spring-summer seasons (planting in mid of February) of 2015, 2016 and 2017 in New Alluvial Zone of West Bengal, at Horticultural Research Station, Mondouri, Bidhan Chandra Krishi Vishwavidyalaya, West Bengal, India, to evaluate the nature and magnitude of genetic divergence in 33 bitter gourd genotypes. Results revealed the presence of wide genetic diversity. The genotypes were grouped into 8 clusters based on Mahalanobis D2 statistics using Tocher’s method. The clustering pattern of genotypes revealed that the genetic diversity was independent of the geographical diversity. Among the 8 clusters, maximum numbers of genotypes were found in cluster II, while clusters IV, VI, VII and VIII was found to be mono genotypic. Among the twenty quantitative characters studied, individual fruit Diameter constituted a maximum of 37.88% contribution to the divergence, followed by internode length. Ranking of genotypes based on intra-cluster mean performance for these characters which are major contributors of genetic diversity revealed its usualness in selecting parents for heterosis breeding.
