Comparison of Three High-Oleic Peanut Cultivars under Varying Field Conditions in the Southwestern United States

ABSTRACT Cultivar selection is one of the most economically important decisions made by peanut producers. The development of genotypes capable of maintaining yield and quality under a wide range of conditions is important so that profitability can be maximized. Issues such as declining irrigation capacity and diseases limit production in parts of Texas. Efforts of the Texas AgriLife Peanut Breeding Program are to develop breeding lines with improved yield potential, total sound mature kernels (TSMK), and disease resistance. Cultivar trials were conducted in 2009, 2010, and 2011 to evaluate the performance of the cultivar Tamrun OL11. Trials were established in several different production areas under various field conditions and included the commercial standards Flavor Runner 458 and Tamrun OL07. Yields were similar for Flavor Runner 458 and Tamrun OL07 at 4538 and 4534 kg/ha, respectively; whereas, Tamrun OL11 averaged 4845 kg/ha (P  = 0.02). TSMK plus sound splits (SS) for Tamrun OL11 were 1.3% higher t...
