Evaluation of 2576 oat germplasm in augmented design showed high range and per cent range of variation for grains/panicle, leaf width, 100-groat and grain weight, and leaf length. Panicle length, seed width, plant height and seed length exhibited medium range as well as per cent range of variation, however, less variations were observed for 50 per cent heading and maturity. Classification of germplasm based on frequency distribution into different classes revealed that majority of the genotypes, concentrated towards mean. Both the extreme types of classes consisted of less number of genotypes.
