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.
