Interpretive Summary:

Technical Abstract: 'VENUS' is a large-seeded high-oleic Virginia-type peanut (Arachis hypogaea L. subsp. hypogaea var. hypogaea) that has enhanced Sclerotinia blight and pod rot tolerance when compared to the cultivar Jupiter. 'VENUS' is the first high-oleic Virginia peanut developed for and proposed for release in the Southwestern U.S. 'VENUS' (experimental designation ARSOK-V30B) is the result of a cross between the cultivar Jupiter, a non high-oleic Virginia peanut released by the Oklahoma Agricultural Experiment Station in 2000, and ARSOK-R2, a high-oleic advanced breeding line. Tests conducted in three locations across Oklahoma in 2012-2014 showed there was no significant difference between the yields of 'VENUS' and Jupiter. However, 'VENUS' graded significantly higher than Jupiter in two out of three locations. 'VENUS' also exhibited enhanced resistance to Sclerotinia blight (61% less) and pod rot (70% less) when compared to Jupiter. 'VENUS' is also similar to Jupiter in shelling and flavor profiles, but unlike Jupiter, it is high-oleic with an average O/L ratio of 26:1. The purpose for releasing 'VENUS' is to provide peanut producers in the Southwestern U.S. with its first high-oleic Virginia peanut, developed specifically for that region, with enhanced grade and disease resistance when compared to Jupiter.
