TUFRunnerTM ‘297’. Georgia-16HO combines high-yield, TSWV resistance with large runner seed size, and the high-oleic trait for longer shelf-life and improved oil quality of peanut and peanut products. Georgia-18RU is a new high-yielding, normal-oleic, TSWV-resistant and leaf scorch-resistant, medium-large seeded, runner-type peanut variety that was released by the Georgia Agricultural Experiment Station in 2018. It was developed at the University of Georgia, Coastal Plain Experiment Station, Tifton, Georgia. During five-years averaged over multiple location tests in Georgia,
Georgia-18RU had the highest percent TSMK grade and the lowest number of seed per pound compared to the Georgia06G runner-type variety. Georgia 18RU was also found to have a similar low percent TSWV and total disease incidence, high yield and dollar value return per acre as Georgia-06G. Georgia18RU combines high yield, high grade, high dollar value, and TSWV and leaf scorch resistance with the desirable normal-oleic trait requested by peanut butter manufacturers. It also has similar roasted flavor, blanchability, and maturity as Georgia-06G. Tifguard is a high-yielding, medium-
maturity, runner market-type peanut variety. It was jointly released by the USDA-ARS and the University of Georgia. It was the first peanut variety with a high level of resistance to both the peanut root-knot nematode and TSWV. Tifguard has a runner-type growth habit with dark green foliage and a prominent main stem. It has demonstrated very good yields and grades when tested with no nematode pressure in tests in Georgia, Alabama, Florida, and South Carolina. When tested in fields with high nematode pressure it has demonstrated very good yields and grades without the use of nematicides. Tifguard also has a moderate level of resistance to leaf spot.
