Genetic divergence in chickpea germplasm

Abstract

Genetic divergence measured by Mahalanobis' D' statistics was carried out with 126 chickpea genotypes available in the germplasm pool. The varieties were grouped into seven clusters. Maximum divergence was observed in the clusters IV and VII and the minimum between the IV and V. The intercluster divergence varied from 0 to 2.99. The maximum intercluster distance was in cluster I with 108 genotypes. The cluster III included kabuli types quite diverse from the desi types and this was again confirmed in the connonical root squre analysis.
