New hihg‐oleic peanut cultivars grown in the Southwestern United States

The chemical composition of five high‐oleic peanut lines grown in Oklahoma was examined. Tamrun OL 01, Tamrun OL 02, TX 977164, and TX 977239 were developed using conventional breeding procedures. SunOleic and Tamrun 96 were the parent lines. These lines demonstrated outstanding agronomic characteristics in Oklahoma. The peanut seeds analyzed in this study contained 42 to 49% oil, 25 to 29% protein, 9 to 12% total dietary fiber, about 2% ash, and 5% moisture. The peanut seeds were rich in potassium. Phosphorus and calcium were the two other two major minerals present in all the samples. The proximate compositions of all the breeding lines were within the range of the parent lines except they had 80% (w/w) oleic acid, which was significantly higher than the parent lines. This study indicates that conventional genetic selection for high‐oleic concentration does not cause substantial unintentional changes in peanut chemical compositions.
