Genetic divergence was studied in 32 genotypes of dolichos bean (Dolichos lablab L.). Nine yield and its contributing characters
were measured by Mahalanobis’s D2 analysis. Thirty two genotypes were grouped in five clusters the highest intra cluster
distance was observed for cluster III followed by cluster V, cluster IV and cluster II. The highest inter cluster distance was
observed between the clusters III and cluster I followed by cluster IV and I and cluster V and I . The minimum inter cluster
distance was noted in between IV and II. The genotypes collected from same geographical location fall in different clusters,
revealed that geographical distance do not contribute to genetic divergence.
