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 ecogeographical regions of the country. On the basis of mean performance of the genotypes for fodder traits; OL 10 for plant height (), OL 1636 for leaf length () and JO 03-95 for leaf width ( cm), OS 7 for GFY () and JHO-2001-1 for DMY ( kg/plot) were found to be superior . | Assessing genetic diversity in dual purpose oat Avena sativa L. cultivars based on morphological and quality traits
