Technical Abstract: Peanut entries (Tamrun 96, Tamrun OL02, and TX 994313) were among peanut lines included in four tests in 2006 and 2007. Plots were planted during May and harvested in late September to mid October to attain a growing season of 155 days. Plots were arranged in a complete randomized block design with 4 replications, and irrigated as needed to ensure good growth. Standard agronomic practices were followed to manage foliar diseases and weeds according to peanut production guidelines for Oklahoma. In 2006, plots were planted at two locations in Caddo County and one location in each of Beckham and Major Counties. In 2007, plots were planted at two locations in Caddo County and one location in each of Beckham and Tillman Counties. Mean yield or grade for each entry by year and location was considered as a random individual event. Data were subjected to standard analysis of variance. There was no entry by year interaction for yield and grade, and therefore, data from the two years were combined for analysis. Yields of 4194, 3931, and 4317 pounds per acre for Tamrun 96, Tamrun OL02, and TX 994313, respectively, were not significant (LSD 0.05 =619). Grades of 68.9, 68.3, and 72.8 for Tamrun 96, Tamrun OL02, and TX 994313, respectively, were significant (LSD 0.05 =3.7). These data showed that the high oleic advanced peanut breeding line TX 994313 exhibited superior grade over Tamrun 96 and Tamrun OL02 under Oklahoma conditions.
