The article highlights the popularity of Udo Peanuts, a special product from Udo, Jeju, used in various food items. Since 2014, the Rural Development Administration and the Jeju Special Self-Governing Province Agricultural Research and Technology Institute have been working on developing a new variety, 'Udo Olle-1', which enhances the health functionality and storage properties of the native peanuts. This new variety has a softer texture, tastier flavor, and a 16% higher yield than conventional peanuts, with double the oleic acid, which extends the preservation period and lowers blood cholesterol. A plant patent for 'Udo Olle-1' has been applied, and the plan is to replace all conventional varieties with this new one by 2025. Farmers and officials are hopeful for the replacement of the conventional species with 'Udo Olle-1', aiming to revitalize the Jeju peanut industry.
