SUMMARY
Oat (Avena sativa L.) is an important cereal cum forage crop of the temperate, sub-temperate and tropical climates of the world. It is a cool season crop cultivated in the Rabi season. The present investigation was conducted to quantify genetic variability, heritability (broad sense), genetic advance, and to elucidate phenotypic performance of the traits governing green fodder yield in oats. Fifty oat genotypes were evaluated in a randomized complete block design with three replications during rabi 2022-23 at CCS Haryana Agricultural University, Hisar. Sixteen morphological and biochemical traits were recorded. Highly significant differences among genotypes were observed for all characters, indicating the presence of substantial genetic variability. High genotypic and phenotypic coefficients of variation were recorded for number of tillers per plant, 100-grain weight and crude protein content. High heritability coupled with high genetic advance (as percentage of mean) was observed for plant height, no. of tillers per plant, leaf: stem, flag leaf length, flag leaf width, panicle length, 100 seed weight and crude protein content, suggesting predominance of additive gene action. Direct selection for such traits is rewarding in green fodder and seed yield improvement in oat.
Key words: Genetic variability and heritability, green forage, seed yield per plant, oat and protein content
