Abstract: A field study was conducted at Research cum Instructional Farm, S.G. College of Agriculture and Research Station, Kumhrawand, Jagdalpur, IGKV, Raipur (C.G.),in Kharif -2019, in a Randomized Block Design with 3 replications to evaluate 11 accessions of finger millet (Eleusine coracana L. Gaertn). The observations of 13 qualitative and 13 quantitative characters were recorded at different stages of plant growth from flowering stage to harvest, according to the Guidelines for the test of DUS on Finger millet by PPV& FRA, Government of India. Genotypes were grouped into three clusters based on the D2 values irrespective of geographical diversities, among which maximum inter-cluster distance was found between cluster II and cluster I, followed by cluster III and cluster II and cluster III and cluster I, which indicates that the use of genotypes from these clusters can serve as potential parents for hybridization. In view of cluster mean and genetic distance, the crossing of entries of cluster I with entries of cluster III would be fruitful for obtaining transgrassive segregants for developing high yielding and better quality finger millet varieties.
