In the present study, an attempt was made to assess the genetic divergence among the 103 kodo millet germplasm accessions using Mahalanobis D² statistic collected from Millet Breeding Station, Coimbatore. The observations were recorded on yield components and nutritional quality traits. The 103 germplasm lines were grouped into 11 different clusters based on D² analysis. Cluster I had a maximum of 63 genotypes, followed by clusters II and III with 14 each, cluster X with four genotypes and cluster VIII with two genotypes. Remaining clusters IV, V, VI, VII, IX and XI were mono-genotypic indicating wide divergence from other clusters. The highest intra cluster distance was observed in cluster X indicating differences in genotypes within cluster. The highest inter-cluster distance was observed between clusters III and X followed by clusters IV and VII suggesting the use of genotypes from these clusters to serve as potential parents for hybridization. The characters days to 50 per cent flowering contributed maximum towards divergence followed by Fe content, Zn content and grain yield per plant.

Keywords: Paspalum scrobiculatum L., Genetic divergence, D2 analysis.
