2019 Crop Science Society of America. All rights reserved. TAMVal OL14 (Reg. No. CV-138, PI 689039) is a high-yielding, high-oleic, early-maturing valencia-type peanut (Arachis hypogaea L. subsp. fastigiata var. fastigiata) cultivar with reduced susceptibility to Sclerotinia blight. TAMVal OL14 was tested under the experimental designation TxL054529-33. Replicated line yield tests began in the F 8 generation in 2007 and ran through 2010. TAMVal OL14 is the first high-oleic valencia peanut released by Texas A&M AgriLife Research and had a maturity (approximately 135 d after planting) similar to New Mexico Valencia C. Yield in breeding trials averaged 706 kg ha 1 higher than for New Mexico Valencia C; in extension trials, the yield advantage ranged from 19 to 33%. Shellout was not statistically different from New Mexico Valencia C, but seed size was larger, 53.7 g 100 sound mature kernels 1 compared with 49.9 g 100 sound mature kernels 1 for New Mexico Valencia C. The frequency of pods with three to five seeds was 37%, not significantly different than the 43% for New Mexico Valencia C. Susceptibility to Sclerotinia minor Jagger was significantly less than New Mexico Valencia C, with a disease incidence of 5.0 to 6.7 for TAMVal OL14 compared with 7.7 to 8.3 for New Mexico Valencia C, on a scale from 0 to 10. The objectives of releasing this line are to provide growers with a higher-yielding and high-oleic cultivar for the valencia market, as well as to reduce the susceptibility of valencia peanut to Sclerotinia blight.
