Oat (Avena sativa L.) is a cool season, annual crop grown mainly in moist areas of temperate climates of the world serving as a food for mankind and forage for cattle. Oat is an important rabi fodder crop in India.In India, oat is also cultivated in Himalayan states like Kashmir, Himachal Pradesh and Uttarakhand. Oat in these regions have a wider adaptability, because of its excellent growing habitat, quick re-growth and better nutritional value (Misri, 2004). Oat breeding programme in Indian regions has not achieved much impetus due to a narrow genetic base of cultivated gene pool within the regionally adapted germplasm. The competition for utilization of land for food grains and fodder necessitates intensified efforts towards more efficient forage research and production, for which it is imperative to characterize and evaluate Avena species in order to identify donors for different traits and diversify primary oat gene pool. Historically, morphological traits have been important in the diversity analysis of crop species. The characterization of germplasm using morphological traits help the plant breeders to select the accessions to be utilized in hybridization programme.
Considering the potential forage value of oats and limited genetic information available at morphological level, present study was aimed to assess the genetic diversity of genus Avena using morphological characterization. The information generated from this study will be helpful in characterizing the genus Avena germplasm and in the selection and utilization of diverse genotypes to enhance variability and productivity of commercial oat for future crop improvement endeavors in the Indian North-Western Himalayan region
