Registration of ‘TAMVal OL14’ Peanut

Résumé fourni par la source

‘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 F8 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.
