‘Georgia-09B’ (Reg. No. CV-110, PI 658595) is a new high-yielding, high-oleic, Tomato spotted wilt virus (TSWV)-resistant, medium-seeded, runner-type peanut (Arachis hypogaea L. subsp. hypogaea var. hypogaea) cultivar that was released by the Georgia Agricultural Experiment Stations in 2009. It was developed at the University of Georgia, Coastal Plain Experiment Station, Tifton, GA. Georgia-09B originated from the first backcross (BC1) made between ‘Georgia Green’ and F2:3 (Georgia Green × GA 942004). Pedigree selection was practiced within the early segregating generations. Performance testing began in the BC1F4:6 generation with the advanced pure-line selection, GA 032902, the experimental designation of Georgia-09B. During three years (2006–2008) averaged over 27 multiple location tests in Georgia, Georgia-09B had significantly less TSWV disease incidence, higher yield and percent total sound mature kernels (TSMK) grade, larger seed size, and greater dollar value return per hectare compared to the check cultivar, Georgia Green. Georgia-09B has also showed significantly higher TSMK percentage and dollar value than ‘York’, ‘AT-3085RO’, and ‘McCloud’ and was found to have a medium runner seed size as compared to the larger high-oleic, runner-type check cultivars, ‘Florida-07’, AT-3085RO, and McCloud. Georgia-09B combines the excellent roasted flavor of Georgia Green with the high-oleic trait for longer shelf life and improved oil quality of peanut and peanut products.
