SUMMARY
The present study was undertaken to assess the genetic diversity present in the 96 oat (Avena sativa L.) germplasm lines representing the collection from various eco-geographical regions of the country. Genetic divergence among 96 accessions was worked out for various morpho-agronomic traits to generate dendrogram based on squared euclidean distance. Maximum inter cluster-distance was recorded between clusters I and VI (9.06) suggesting significant high genetic diversity among genotypes of these clusters. The best 20 genotypes identified on the basis of 10 per cent higher grain yield than the best check OL 10 were UPO 093, OL 1611, JHO-2001-1, HJ 114, OS 374, OL 1542, A. maroccana, JHO 851, OL 1635, OS 329, SKO 27, HJ 8, OS 363, EC 209408, EC 209402, OL 1714, OL 1685, OS 376, EC 605833 and JHO-2009-1.
