Interpretive Summary: Peanut production in Oklahoma is generally located in three geographical regions across the state: southwestern, west-central, and far west. Each region differs from the others in environmental and biological stressors that affect crop production, so the same peanut cultivar will likely perform differently in each growing region. Therefore, the Oklahoma Peanut Variety trials are conducted in each region annually and are designed to test the performance of commonly grown cultivars and potential cultivar releases against each other. Results of these annual trials can serve as a guide for producers when choosing a cultivar to plant. State-wide peanut variety trials were conducted in three Oklahoma locations. Performance of runner, Spanish, and Virginia entries were assessed. Performance of runner varieties depended on location but averages across locations indicate that advanced breeding line ARSOK R47A was the top performer. No significant differences were seen among spanish entries across locations and over years, but cultivars AT-9899 and OLé performed best numerically. The high-oleic virginia-type breeding line ARSOK V85-377 numerically out-yielded all other virginia entries across locations in 2017 and across years and locations for 2016-2017.
