Interpretive Summary: 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 long-term averages across locations indicate that advanced breeding lines ARSOK-R47A and ARSOK-R37 were the top performers, followed by cultivars Tamrun OL11 and Lariat. Cultivar AT98-99 was consistently the highest yielder across locations and years, most likely due to the prostrate (runner-type) growth habit. No significant differences were seen between spanish cultivars OLé and Tamnut OL06 across locations and over years. The new virginia breeding line ARSOK-V377 out-yielded all other Virginia entries across locations in 2016. However, among those virginia entries that had been tested for at least four years, no significant differences were observed in yield or grade.

Technical Abstract: Managed peanut variety trials located in various state-wide regions are an essential part of peanut variety development and release. In this study, trials were conducted in Caddo, Custer, and Tillman counties of Oklahoma. Trial entries included 12 runner types, 4 Spanish types and 8 Virginia types. Unusually cool weather in August and September may have contributed to grades lower than normal but yields in 2016 were above average. Overall, 2016 was an above average year for agronomic performance, reflected in yields across locations and market-types. Performance of runner varieties depended on location but long-term averages across locations indicate that advanced breeding lines ARSOK-R47A and ARSOK-R37 were the top performers, followed by cultivars Tamrun OL11 and Lariat. Cultivar AT98-99 was consistently the highest yielder across locations and years, most likely due to the prostrate (runner-type) growth habit. No significant differences were seen between spanish cultivars OLé and Tamnut OL06 across locations and over years. The new virginia breeding line ARSOK-V377 out-yielded all other Virginia entries across locations in 2016. However, among those virginia entries that had been tested for at least four years, no significant differences were observed in yield or grade.
