SUMMARY
The present study was conducted during winter season of 2016-17 with 27 diverse oat genotypes. On the basis of D2 values all the twenty seven genotypes studied were grouped into six clusters. Cluster I with ten genotypes emerged as the largest cluster followed by Cluster II and cluster III with seven genotypes each. Cluster IV, V and VI were solitary clusters. The highest intra cluster distance was observed for the cluster III containing seven genotypes, followed by cluster II containing 7 genotypes and cluster I containing 10 genotypes. The maximum (%) contribution towards genetic divergence was contributed by green forage yield followed by leaf/stem ratio and leaf length. The superior genotypes identified for hybridization for green forage yield improvement were Phule Surabhi, ROG-15-3, ROG-15-11, ROG-15-19, Phule Harita and ROG-15-24.
