 ABSTRACT

A trial was conducted to Studies on heterosis and transgressive segregants for fodder and grain related traits in Oat (Avena sativa  L. ) in a diallel cross set of 8  parents, 28 F1 s and 28 F2  s  oat were evaluated in randomized complete block design with three replications. The genetic parameters estimated for the traits   based on mean performance, narrow sense heritability and genetic advance. The high heritability coupled with high genetic advance was observed for green fodder yield, dry matter yield and plant height in both the generations. High heritability with moderate genetic advance was found for days to 50 % flowering, seed per panicle, hecto lit. Grain weight and groat % in both generation indicating that selection in later generations would be much rewarding.

Key words: Generation, Grand mean Heritability (narrow sense) and Genetic advance in per cent of mean.
