0PI 689039'TAMVal OL14'Arachis hypogaea L. subsp. fastigiata Waldron Texas, United StatesPVPONot Available2018DEVELOPEDCultivarBotanical Characteristics. TAMVal OL 14 is a valencia peanut, with erect growth habit and flowers present on the mainstem. Agronomic Traits. Yield testing revealed that TAMVal OL 14 outyielded New Mexico Valencia Cover years from 2007 to 2010, 4388 kg/ha to 3682 kg/ha, or by 19%. TAMVal OL 14 was not significantly different in maturity than New Mexico Valencia C. Percentage of 3-and 4-seeded pods was not significantly different from New Mexico Valencia C. Seed and Pod Characteristics Yield Under Disease-Free Conditions. TAMVal OL 14 had a mean oleic:linoleic fatty acid ratio of 27. 5: 1 (based on mean of seed 0/L ratios), with an oleic acid percentage of 82. 7% of total oil, and linoleic acid percentage of 3.0%. Mean seed size ofTAMVal OL 14 was 53.7 g /100 SMK, and was significantly larger than New Mexico Valencia C (49.9 g /100 SMK). Upon shelling, TAMVal OL 14 had a larger proportion of extra large kernels (19.1% vs 14.5%) than New Mexico Valencia C, but smaller proportions of mediums (37.1% vs 40.5%) and number ones (7.4% vs. 9.5%). Disease-resistance and Yield under Sclerotinia Blight (Sclerotinia minor Jagger) Conditions. Trials were conducted in the Sclerotinia nursery in Stephenville in 2007 and 2008, and results indicated that TAMVal OL 14 was less susceptible (ratings of 6.7 and 5.0) to Sclerotinia than was New Mexico Valencia C (ratings of 8.3 and 7.7). TAMVal OL 14 also yielded significantly higher (3341 and 3029 kg/ ha) under these conditions than did New Mexico Valencia C (2320 and 1976 kg/ha). 1967611PI 689039
