Genetic variability, heritability and genetic advance studies for different characters on green fodder yield in oat (Avena sativa L.)

The experimental material for present study consisted of 30 diverse genotypes of oat. Observation were recorded on 11 quantitative traits in oat. High estimates of heritability (broad sense) were obtained for all the characters. The magnitude of PCV as expected was greater than the corresponding GCV for all the characters indicating importance of environment in expression of characters On the basis of result Out of 11 characters studied seeds per panicle, dry matter yield per plant, green fodder yield per plant and harvest index showed high GCV and heritability coupled with high genetic advance as percent of mean which revealed that these four traits might be under control of additive gene effects and therefore they are more reliable for effective selection.
