Multi-environment analysis of grain yield and quality traits in oat (Avena sativa L.)

Oat is used for food, in animal feeding and non-food products. Twenty-five oat genotypes were evaluated at six different environments to determine high-yielding, good-quality stable genotypes. Experiments conducted randomized blocks design with 4 replications. Grain yield, plant height, test weight, thousand-grain screening percentage, groat protein, ?-glucan starch contents 25 Genotype, environment genotype × interaction had extremely important effects on yield quality of grains. The additive main multiplicative interactions analysis disclosed environmental addition by according grain yield. Using AMMI analysis, three promising (G1, G3 G4) defined comparison the cultivars these 4.03, 3.77 3.70 t ha-1, respectively. AMMI-2 biplot revealed that E6 was most discriminating Genotype-by-trait (GT) explained 54.9% total variation. positive associated all traits except height. G1, G4 genotypes, which showed best performance higher stability, also good traits.
