Interpretive Summary: In the Southwestern U.S. peanut production region (largely Oklahoma and Texas), the majority of cultivated peanut varieties are high oleic. Peanuts of the Spanish market-type, which are commonly consumed in candies and mixed nut products, are grown mainly in Oklahoma and Texas and are in high demand. Spanish type certified seed stocks have become contaminated and are no longer high oleic by industry standards. The peanut industry is in urgent need of replacement high oleic Spanish peanut cultivars with an acceptable seed size, yield and disease resistance package. OLé peanut (experimental designation ARSOK-S140-1OL) is a high oleic Spanish-type peanut that was cooperatively released by the USDA-ARS and the Oklahoma Agricultural Experiment Station in 2014. In 6 years of advanced breeding line performance trials across three locations in Oklahoma, OLé yield averaged 407 kg ha**-1 more than that of OLin, and had significantly less incidence of Sclerotinia blight and pod rot. Overall, field performance data indicate that production of OLé instead of OLin would result in a $150-$400 ha**-1 increase for peanut producers.

Technical Abstract: OLé peanut (experimental designation ARSOK-S140-1OL) is a high oleic Spanish-type peanut (Arachis hypogaea L. subsp. fastigiata var. vulgaris) that was cooperatively released by the USDA-ARS and the Oklahoma Agricultural Experiment Station in 2014. OLé is the product of a Tamspan 90 X F435, the original donor of the high O/L gene. Pedigree methodology was employed in screening early segregating populations. Advanced breeding line ARSOK-S140-1OL was identified due to its enhanced Sclerotinia blight and pod rot resistance. In 6 years of advanced breeding line performance trials across three locations in Oklahoma, OLé yield averaged 407 kg ha**-1 more than that of OLin, and had significantly less incidence of Sclerotinia blight and pod rot. Overall, field performance data indicate that production of OLé instead of OLin would result in a $150-$400 ha**-1 increase for peanut producers.
