Description
The genetic bottleneck of cultivated peanuts (Arachis hypogaea) often limits the improvement of traditional breeding programs. To tackle this constraint, chemical mutagenesis via Ethyl Methane Sulfonate (EMS) serves as a valid strategy to induce novel allelic variations. This study primarily focuses on the development and screening of an extensive EMS-mutagenized peanut population by applying a forward genetics approach to determine and isolate high-yield individuals with significantly altered fatty acid content.
The screening process targets the fatty acid biosynthesis pathway, looking to modify the ratio of oleic to linoleic acid, observing the functional changes in the FAD2 (fatty acid desaturase) gene family. By identifying “high oleic” mutants, we aim to provide the industry with peanuts that demonstrate superior seed profiles prospectively contributing to human cardiovascular health, high nutritional-value animal feed, increased shelf stability as well as a potential use in cosmetic and biodiesel industry – all while preserving or improving overall agronomic and economic value for the U.S market.
