Genetic divergence in greengram (Vigna radiata (l.) Wilczek)

The present investigation was undertaken to provide information on nature and magnitude of genetic diversity among the sixty promising greengram germplasm by using Multivariate analysis. Cluster analysis indicated the presence of considerable genetic divergence among the genotypes. The genotypes were grouped into 8 clusters using Toucher Method. Cluster V showed maximum Intra clusters distance while the highest inter clusters distance was observed between clusters VII and VIII. The cluster VIII has high mean for days to maturity, plant height, number of clusters per plant and seed yield per plant. Therefore, it was concluded that more emphasis should be given on cluster VIII for selecting genotypes as parents for crossing with the genotypes of cluster VII which may produce new recombinants with desired traits.
