Registration of ‘Tamrun OL18L’ and ‘Tamrun OL19’ peanut

‘Tamrun OL18L’ (Reg. no. CV-155, PI 703068) and ‘Tamrun OL19’ (Reg. no. CV-156, PI 703069) are high-yielding, high oleic, early-maturing runner-type peanut (Arachis hypogaea L. subsp. hypogaea) cultivars. Tamrun OL18L was derived from a cross between a high oleic runner cultivar, ‘Tamrun OL02’, and TxL017746, an early runner breeding line selection developed from a cross between PI 109839 and ‘Florunner’. Tamrun OL19 was derived from a cross between a high oleic runner cultivar, ‘Tamrun OL01’, and TxL017746. Maturity of Tamrun OL18L was similar to ‘Tamrun OL12’, approximately 2 weeks earlier than ‘Tamrun OL07’. Tamrun OL19 matured approximately 1 week earlier than Tamrun OL07 and 1 week later than Tamrun OL12. Grades of Tamrun OL18L and Tamrun OL19 were similar, intermediate numerically between but not statistically different from Tamrun OL07 and Tamrun OL12; by comparison, Tamrun OL12 had a significantly lower grade than Tamrun OL07. Grades of Tamrun OL18L and Tamrun OL19 were lower than ‘Tamrun OL11’ but were similar to ‘Georgia-09B’, ‘FloRun 107,’ and ‘TUFRunner 511.’ Yields were similar to Georgia-09B, FloRun 107, and TUFRunner 511 but were higher than ‘Tamnut OL06’ and Tamrun OL11. Tamrun OL18L had a larger seed than most cultivars tested, significantly larger than Tamrun OL12 and Tamnut OL06, but was similar in size to Tamrun OL07 and ‘Webb’. No differences in flavor were noted between Tamrun OL18L, Tamrun OL19, and check cultivars.
