Oats are a significant global cereal crop, ranking seventh in production among major cereals. This study examines both global and domestic trends in oat production, offering insights into the supply and demand for forage oats and outlining future prospects. Oats are cultivated on 8.0 million hectares worldwide, yielding approximately 19 million tons annually. Russia and Canada lead in production, together contributing nearly 30% of the global output. The United States is the largest importer, accounting for 1.5 million tons, or 38.7% of global imports, followed by Germany and China. In Korea, oat imports reached 25,000 tons in 2023, while exports surged more than 86-fold from 1.07 tons in 2015 to 92.3 tons in 2023, driven by increasing international demand. Since 2001, domestic breeding programs have aimed to develop superior forage oat varieties, such as ‘Samhan’ recognized for its winter hardiness when fall-sown, and ‘Highspeed’ appreciated for its early maturity when summer-sown. Consequently, the self-sufficiency rate for forage oat seeds has doubled, rising from 21% in 2020 to 42.4% in 2023. These advancements in domestic variety development and seed self-sufficiency are poised to significantly enhance the industry’s future, particularly when supported by a more efficient and streamlined distribution system.
