Genetic Diversity Studies in Dolichos Bean [Lablab Purpureus Var. Typicus] for Growth, Yield and Quality Parameters

Twenty-three diverse types of dolichos beans
were evaluated for yield and their contributing
characteristics. Genotypes were grouped into seven
clusters on the basis of the relative magnitude of D2
values. The maximum inter-cluster distance was
observed between cluster III and cluster VI followed by
clusters V and VI. The minimum inter-cluster distance
was observed between cluster I and cluster VII. The
maximum intra-cluster distance was in cluster VI
followed by cluster IV. The mean value for most of the
traits was highest in cluster V. Pod yield plant-1
followed by crude fibre, crude protein and number of
seeds pod-1 and green pod girth contributed higher
towards genetic divergence. Hence, that the genotypes
from cluster V and cluster I could be selected for crop
enhancement.
