Abstract: This study investigated the forage dry matter yield, winter hardiness, and season type of various winter oat genotypes from the Epagri germplasm bank in Santa Catarina, Brazil. Key findings include: Significant yield variation: Genotypes displayed a wide range in dry matter yield, with substantial decreases observed between 2021 and 2023, potentially due to weather and planting date changes. Winter hardiness diversity: Scores ranged from highly tolerant (1) to highly susceptible (3), highlighting the potential for breeding programs to select winter-hardy lines. Multiple season types: Genotypes were classified as winter, spring, or alternative based on heading date, offering flexibility for year-round grazing depending on specific needs. Yield-hardiness relationship: A negative correlation suggests that as winter hardiness increases, yield may also increase. No yield-season type association: Season type did not significantly impact overall yield.
