ABSTRACT
The present study aims to reveal the importance genetic diversity existing in the 274 finger millet germplasm accessions. Based on D2 values, 274 reference set genotypes were grouped into 8 clusters. 77 accessions present in cluster I, two accessions were present in cluster II, while cluster III and IV had 4 accessions each, 59 accessions present in V, cluster VI and VII had two accessions each and 124 accessions belongs to cluster VIII . The intra cluster distance varied from 1.81 in cluster II to a maximum distance of 13.45 in cluster III. This reveals the presence of diverse accessions within different clusters. Among the 14 quantitative characters studied, the most important character contributing to the divergence in reference set was ear weight which is mainly responsible for increasing grain yield. Based on the overall score across 14 traits, the cluster IV received first rank followed by cluster V, III, VIII, I, VII, II and VI.
