OLé (Reg. No. CV-128, PI 674164) peanut (experimental designation ARSOK-S140-1OL) is a high-oleic spanish-type (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 the cross ‘Tamspan 90’ × F435. The male parent, F435, is the original donor of the high-oleic genes. Pedigree methodology was used in screening segregating populations. The advanced breeding line ARSOK-S140-1OL was identified due to its enhanced resistance to Sclerotinia blight (causal agent Sclerotinia minor Jagger) and pod rot (causal agents Pythium myriothylum and/or Rhizoctonia solani). In 6 yr of advanced breeding line performance trials across three locations in Oklahoma, OLé yielded an average of 4048 kg ha⁻¹ and had less incidence of Sclerotinia blight in 2009 to 2011 and 2013 and less pod rot in 2009 and 2010 (P < 0.05) compared with OLin. Overall, field performance data indicate that production of OLé instead of OLin could save producers $150 to $400 ha⁻¹ annually in disease management input costs.
