Stability analysis of spring oat genotypes in south-west Poland

Oat is a grain in high demand, due to its physiological and nutritional attributes as a functional food. Oat is rich in glucans, and high in tocopherol and other dietary fibre components. It is also used for forage, fodder, chaff and as a major component of infant foods. In the present study, oat yi...

Description
Summary:Oat is a grain in high demand, due to its physiological and nutritional attributes as a functional food. Oat is rich in glucans, and high in tocopherol and other dietary fibre components. It is also used for forage, fodder, chaff and as a major component of infant foods. In the present study, oat yields from six experimental stations in south-western Poland, obtained in 2019–2022, were analysed using three different linear mixed models that can be associated with three different stabilities. It is shown that the genotype Perun had the highest mean yield among the tested genotypes, while the genotype Armani was the most stable. Armani and Pablo had the lowest values of the GSI index, making them the most favourable genotypes for cultivation in that region.
