ABSTRACT
Genetic divergence was studied in finger millet with 11 characters viz., grain yield per plant, main ear width, total no. of basal tillers per plant, total no. of fingers on the main ear, finger width, main ear length, plant height, no. of leaves on the main tiller, total productive tillers per plant, finger length and grain yield per plot, which partitioned the 48 germplasm lines into eight clusters. Maximum number of germplasm lines (24) were included in cluster I followed by twelve germplasmlines in cluster II, five germplasm lines in cluster IV, cluster VI with three genotypes and one each in cluster III, V, VII and VIII. The maximum intra-cluster distance was shown by cluster VI. Maximum divergence was observed between cluster VI and VIII, while minimum was between cluster I and V suggesting, more variability in genetic makeup of germplasm lines included in these clusters.
Among the 11 quantitative traits studied, the most important trait contributing to the divergence was grain yield per plant followed by main ear width, total no. of basal tillers per plant, total no. of fingers on the main ear and finger width. Usefulness of parents has been identified based on genetic divergence for improving finger millet. Higher yielding clusters were VI, II and IV.
Key words: Finger Millet, Cluster, Diversity, Divergence.
