Genetic diversity analysis in greengram and blackgram

E01442

Genetic divergence of 80 genotypes of greengram and blackgram was studied by using principal component analysis (PCA). Clusterning based on PCA scores separated the genotypes into seven clusters. Appropriateness of the clustering pattern was indicated by sequential "F" test. Intra cluster distance was narrow, which indicated that cluster composition was fairly homogenous. Pattern of clustering was such that greengram and blackgram genotypes separated into distinct clusters. This indicated that both greengram and blackgram have evolved into two distinct species. Average intercluster distance was more among the blackgram genotypes. This indicated high degree of genetic among the 40 blackgram genotypes.
