ABSTRACT

Evaluation of 48 genotypes of cluster bean was taken up in dry land farm of S.V. Agricultural College, Tirupati in a
randomized block design with three replications during kharif, 2014. Based on Mahalanobis D2
analysis, 48 genotypes were
grouped into 12 clusters. Genotypes that originated from different eco-geographical regions grouped together in the same cluster
which suggested that there was no correlation between geographic diversity and genetic diversity. The maximum inter-cluster
distance was recorded between cluster IX and cluster XI, while the minimum inter-cluster distance was found between II and III
cluster.

KEY WORDS:
