Abstract
An experiment was conducted with 125 germplasm accessions and five check varieties of Oat (Avena sativa L.) in augmented design during rabi, 2019-20. Nineteen quantitative traits were studied for the assessment of genetic variability. Sufficient variation was exhibited by most of the traits studied. The highest values for GCV and PCV was observed for leaf:stem ratio and seed yield per plant. High heritability and high genetic advance as per cent of mean were observed for 1000 seed weight and leaf:stem ratio. High heritability combined with high genetic advance is the indication of additive gene action and selection based on this would be more effective. The skewness value for most of the traits studied in Oats ranged from -0.5 to 0.5 which indicate that these traits are normally distributed except for days to 50% flowering, flag leaf length, the number of tillers per plant, leaf dry weight per plant and leaf: stem ratio. Plant height, flag leaf width, culm diameter, dry matter yield per plant, stem dry weight per plant and seed yield per plant exhibited negative kurtosis (platykurtic). Keywords: Variability, Skewness, Kurtosis, Forage yield and Oat
