Genetic divergence in hyacinth bean (Dolichos lablab)

A study conducted during 1994-95 to analyse the genetic diversity using Mah alanobis D-2 statistic was carried out in 28 genotypes of hyacinth bean (Do lichos lablab L.). These genotypes were grouped into 5 clusters. Cluster I had 22 genotypes. The analysis further indicated that the genotypes of comm on geographic origin or same location were grouped into different clusters which suggested a lack of relationship between genetic and geographic diver sity. The average intercluster D-2 values indicated maximum statistical div ergence between cluster II and V followed by I and V and I and IV. Cluster V recorded highest mean pod length, pod weight, seeds/pod and green pod yie ld/plant. The first 2 canonical vectors accounted for 73.09% of total genet ic variation.
