SUMMARY
Genetic divergence was studied for 130 Oat germplasm accession including 5 checks (JHO851, RO-19, JHO-822, UPO-212, JO-1). Experiment was conducted in augmented design in Rabi 2019-20. All the 130 germplasm accessions were grouped into 12 clusters. Cluster I comprised by highest number of genotype followed by cluster III, cluster V, cluster X, and cluster VI. Seven cluster II, IV, VII, VIII, IX, XI, XII had lowest number of genotype. Wide range of intra cluster distance obtained. Highest intra cluster distance obtained by cluster VIrepresent the high genetic diversity among the genotypes. The highest inter cluster distance found between Cluster X and XI. Highest genetic divergence contributed by 1000 seed weight, green fodder yield and seed yield per plant.
Key words: Genetic divergence, intra cluster distance, inter cluster distance, genetic diversity
