ABSTRACT
Genetic divergence was studied among sixty one genotypes of ragi using Mahalanobis D2 for six nutritional and eleven quantitative characters. The genotypes were grouped into seven clusters. The mode of distribution of genotypes from different eco-geographical regions into various clusters was at random indicating that geographical distribution and genetic diversity were not related. The characters viz., zinc content, copper content, days to 50% flowering, iron content, protein content and calcium content contributed maximum towards diversity. The maximum inter-cluster distance was observed between the clusters II and VII and cluster III and VII. Hence, genotypes from these clusters namely IE-5537 and IE-5106 (Cluster VII), PPR-1012 (Cluster II), IE-4816, VR-708 and VL-349 (Cluster III) could be suggested for inclusion in hybridization programme for obtaining superior and desirable recombinants.
