Finger millet is the third most important millet grown in many states of India under diverse situations of soil, temperature and rainfall. Genetic improvement through conventional breeding approaches depends mainly on the availability of the diverse germplasm and the amount of genetic variability present in the population. In the present study, 150 finger millet germplasm had been studied for their variability and diversity for 12 charactcrs. The analysis of variance showed highly significant differences among the genotypes for all the 12 characters studied. High heritability and high genetic advance were noted for number of tillers and single plant yield, indicating the possibility of improvement for this trait by simple selection. Genetic diversity among 150 finger millet acccssions was worked out using Mahalanobis DJ statistics. Based on genetic distance, these genotypes were grouped into 18 clusters. The present study concluded that considerable amount of gcnctic diversity is present among the entries for yield and yield attributes. Fourteen solitary' clusters were superior viz., II, III, V, VI, VIII, X, XI, Xll, XIII, XIV, XV, XVI, XVII and XVIII. Inter crossing between genotypes of these diverse clusters would generate a broad spectrum of variability for effective selection in the segregating generations for the development of high yielding cultivars.
