Hundred genetic resources of foxtail millet were subjected to multivariate analysis through Wards’ minimum variance method that grouped them into eleven clusters. Cluster III (16) was maximum followed by cluster VIII (14), cluster IX (12), cluster VII (11) and cluster V (10). The clusters IV, VI and XI comprised of eight genotypes each. Seven and five genotypes were grouped in clusters X and II, respectively. The cluster I registered as monogenotypic / solitary cluster. Considering the distribution of genotypes, it can be concluded that cross between SiA 3222 x SiA 3580 has good chance of generating heterotic hybrids or transgressive segregants, depending on the gene action controlling the traits.

Keywords : Foxtail Millet, Genetic Divergence, Hierarchical Cluster Analysis, Wards’ Minimum Variance.
