Weed Management in Oklahoma Peanut

A major goal of the ARS peanut research program in Stillwater is to develop and release high-oleic peanut cultivars for the Southwest with improved yield, disease resistance and seed characteristics. In 2018, commercial and advanced breeding lines of runner, Spanish and Virginia peanuts were evaluated in small plots at OSU's Caddo Research Station at Fort Cobb. The objectives of these field studies were: 1) to compare advanced or newly released lines to commercially available cultivars in agronomic quality (e.g. yield and seed grade) and disease resistance to soilborne diseases and 2) to evaluate a selection of Virginia entries for pod rot resistance in field where moderately high levels of pod rot were observed in 2017.
