Interpretive Summary: Performance of runner varieties depended on location but averages across locations in 2020 indicate that cultivars Lariat was the top entries in value per acre. Significant differences among Spanish entries across locations and years indicated OLé had the top yield but that the small-seeded runner-type cultivars AT98-99 and Span17 were the leaders in value per acre. No significant differences were noted in Virginia entry yields across locations and years (2019-2020) but numerically Contender and the breeding line NCEX17 led the entries in value per acre. Pod size distribution analysis reported for all variety trial locations as well as the Caddo Co. Uniform Peanut Performance Test (UPPT) indicate that several breeding lines tested have significant increases in percent super jumbo pods when compared to cultivars currently in production.
