Abstract

Abstract : 'Contender' (Reg. No. CV‐139, PI 689511) is a large‐seeded high‐oleic virginia‐type peanut ( Arachis hypogaea L. subsp. hypogaea var. hypogaea ) cultivar with enhanced pod size distribution and seed size when compared to the virginia‐type cultivar VENUS. Released jointly by the USDA‐ARS and Oklahoma Agricultural Experiment Station in 2018, Contender (tested as ARSOK V85‐377) is the result of a cross between the high‐oleic virginia cultivar Brantley and high‐oleic runner cultivar Red River Runner. Contender had an average pod yield of 6446 kg ha −1, a grade (total sound mature kernels [TSMK]) of 69%, and 55% extra‐large kernels (ELK), giving it the highest estimated value for the producer among the virginia‐type cultivars tested in Oklahoma Cultivar Trials for 2016–2017. Contender's average super jumbo count per kilogram and average pod brightness (Hunter L) score were reported at 318 kg −1 (9 oz −1 ) and 50, respectively, indicating that this cultivar has large, bright pods, which are necessary components of any market‐worthy virginia cultivar. When entered in the national Uniform Peanut Performance Test (UPPT), Contender performed well in all locations, averaging 5646 kg ha −1, 75.6% fancy pods, 58% ELK, a sound mature kernel weight per 100 seed of 90 to 104 g and a TSMK of 71.7%. The purpose for releasing Contender is to provide peanut producers in the southwestern United States with a high‐oleic virginia peanut developed specifically for that region that has enhanced pod size distribution and larger seed size compared with VENUS.
