Genetic variability was estimated among 34 genotypes of M6 generation were derived from oat genotypes Kent and JO-1 during rabi 2010 at All India Co-ordinated Research Project on Forage crops, Seed Breeding Farm, JNKVV, Jabalpur (M.P). The materials for the present study comprises of genotypes which were selected on the basis of performance for fodder yield and yield contributing characters in M5 generation. In JO-1 population, the genotype JMO-187 and in Kent population the genotype JMO-429 recorded maximum total green fodder yield. High phenotypic and genotypic coefficient of variation was recorded for crude protein yield followed by leaf area, total dry matter yield and total green fodder yield which indicated the presence of ample amount of variation for these characters. High values of heritability coupled with high expected genetic advance were observed for the characters viz., leaf area and axis length suggesting the scope for selection.
