Description
Summary:The genetic divergence of forty bitter gourd genotypes was studied for sixteen different parameters by adopting Mahalanobis D2 statistics using Tocher's method. The genotypes were grouped into six clusters irrespective of geographic divergence, indicating no parallelism between geographic and genetic diversity. A maximum of 32 genotypes entered in cluster I, followed by 4 genotypes in cluster II. The cluster III, IV, V and VI had single genotypes each. The maximum inter-cluster distance was obtained between cluster II and VI (1620.05) while minimum distance was between III and V (103.32). Cluster V followed by cluster VI showed superiority for yield and other desirable traits, which indicate the potentiality of these diverse genotype collection for providing basic material for future breeding programmes.
