There is abundant genetic variation in peanut oleic acid content. Compared with common oleic acid peanuts, high oleic acid peanuts are favored by consumers due to their high monounsaturated fatty acids. Increasing the content of oleic acid and decreasing the content of linoleic acid (increasing O/L value) played the key role in peanut quality improvement and had the major interest of domestic and foreign research. It is very important to im? prove people′s living standard and health through breeding the improved composition of fatty acid. Based on the characteristics of FAD2 genes of the fatty acid dehydrogenase, the research progress of molecular markers of pea? nuts with high oleic acid, the detection technology of oleic acid content and the breeding methods of peanuts with high oleic acid were reviewed. Subsequently, the new varieties of high-oleic acid peanuts developed in China and the United States at the present situation and prospect of high-oleic acid peanut breeding were summarized.
