The present study was undertaken to assess the genetic diversity present in the ninety six oat (Avena sativa L.) germplasm lines representing the collection from various eco-geographical regions of the country. On the basis of mean performance of the genotypes for fodder traits; OL 10 for plant height (60.09cm), OL 1636 for leaf length (53.55cm) and JO 03-95 for leaf width (1.86 cm), OS 7 for GFY (3.38kg/plot) and JHO-2001-1 for DMY (0.61 kg/plot) were found to be superior. Similarly, on basis of mean performance of the genotypes for grain traits; OS 7 for beta-glucan (4.35%), JHO-2009-1 for grain length (15 mm), OL 1542, OL 1611, OL 1615, OL 1636, OL 1635, JHO 851, EC 605839, EC 605833, EC 209750, EC 209472, EC 209408, SKO 315, SKO 312, and RO-2001-1 for grain width (3.3 mm) and UPO-093 for grain yield (426.91 g/plot) were found to be superior. Genetic divergence among 96 accessions was worked out for fodder and grain traits and then for dual purpose to generate dendrogram based on complete linkage and squared euclidean distance. All the 96 accessions were grouped into 6 clusters. Maximum inter cluster distance for fodder, grain and dual purpose was recorded between clusters VI and III (9.99), clusters I and VI (9.06), clusters IV and V (11.24) respectively, suggesting significant high genetic diversity between genotypes of these clusters. According to criteria followed by Proceedings of AICRP (FCU 2015), the 14 best dual purpose genotypes evaluated are: UPO 093, OL 1611, JHO-2001-1, HJ 114, JHO 851, OL 1635, OS 329, SKO 27, HJ 8, OS 363, OL 1714, OS 376, EC 605833 and JHO-2009-1.
