Genetic divergence studies in Dolichos bean (Lablab purpureus L.) genotypes

Abstract

Studies was carried out to assess the genetic divergence among 38 dolichos bean genotypes using Mahalanobis D2. 38 genotypes were grouped into seven clusters. Cluster I had highest number of genotypes (11) followed by cluster VII (9), cluster V (7), cluster VI (4), cluster II and cluster III (3), cluster IV (2) having 1 genotype. The maximum inter cluster distance was observed between cluster no. III and VII (62168.95) and cluster no. IV and V (2078.16) showed minimum inter cluster distance. The highest intra cluster distance was recorded for cluster no. III (1903.00) and cluster no. V (1176.59) showed minimum intra cluster distance.
