GENETIC DIVERGENCE IN CHICKPEA (CICER ARIETINUM L.)

Published on

In order to assess the divergence among the 17 genotypes, 5 each developed through
mutation breeding and intra- and interspecific hybridization and two standard checks
in chickpea, Mahalanobis' D2 statistics was applied. These genotypes were grouped
into five clusters. Clusters II, I and III had 6, 5 and 4 genotypes, respectively. On
the other hand, the clusters IV and V had only one genotype each. The genotypes
falling in cluster III had the maximum divergence which were closely followed by
those of clusters II and I. The maximum and minimum divergence was revealed
between clusters II and V and between III and V, respectively. In general, the
clusters II and V exhibited high and low mean values, respectively for most of the
characters. It has been suggested that for varietal improvement the hybridization
among the genotypes of divergent clusters should be done rather than depending
on those genotypes of the cluster having minimum divergence.
