ABSTRACT

In the present study, the genetic divergence among 100 germplasm accessions was assessed using Mahalanobis D² statistics. The genotypes were collected from different sources and the standard varieties were also included in the study. The experiment was carried out during Rabi 2009 at Regional Research Station, Paiyur. The observations were recorded on seed yield and its components. Based on D² analysis, the 100 germplasm lines were grouped into sixteen different clusters. The cluster VI was the largest with 43 genotypes followed by cluster I (14) and cluster XV (11). The cluster XIV showed the maximum mean value for seed yield followed by cluster VII. The intra and inter cluster divergence among the genotypes was varying in magnitude. Further it implies that the intra-cluster distance was maximum in cluster I followed by clusters II and XV. The widest inter cluster distance was noted between cluster I and XIII giving scope for hybridization among these genotypes for improvement of traits through pedigree breeding. The distance between clusters X and XII was minimum indicating close relationship between those clusters.
