Interpretive Summary: State-wide peanut variety trials were conducted in three Oklahoma locations. Performance of runner, Spanish, and Virginia entries were assessed. ARS high-oleic runner breeding lines ARSOK-R35 and ARSOK-R37 consistently out-performed available runner cultivars across locations and over a period of 3 years. Spanish cultivar AT99-98-14 consistently performed best at most locations over the last several years compared to other entries. High-oleic Virginia breeding lines ARSOK-V30B, ARSOK-V31, and ARSOK-V41 performed very well at most locations. These tests will aid in screening peanut advanced breeding lines for agronomic performance.

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, Beckham, and Custer counties of Oklahoma. Trial entries included 10 runner types, 4 Spanish types, and 6 Virginia types. Overall, 2014 was an outstanding year for agronomic performance, resulting in high yields and grades across locations and market-types. ARS high-oleic runner breeding lines ARSOK-R35 and ARSOK-R37 consistently out-performed available runner cultivars across locations and over a period of 3 years. ARSOK-R35 demonstrated an extremely high level of pod rot resistance under intense disease pressure. Spanish Cultivar AT99-98-14 was a top performer consistently across locations and over the last 3 years. In most cases, no statistical differences between cultivars OLé and Tamnut OL06 were noted over a 3 year period. Tamnut OL06 proved to be extremely susceptible to pod rot infection under high disease pressure. High-oleic Virginia breeding lines ARSOK-V30B and ARSOK-V41, and cultivar Florida Fancy were the top performers in Virginia tests across locations and over a 3 year period. Breeding lines ARSOK-V30B, ARSOK-V41, and cultivar Florida Fancy all demonstrated enhanced pod rot resistance when compared to other Virginia-type entries. These tests will aid in screening peanut advanced breeding lines for agronomic performance.
