Interpretive Summary: White mold is one of the most damaging diseases of peanut with regards to both costs of control and yield loss in the southeastern United States. TifTB is a high-oleic acid peanut cultivar with a high level of resistance to white mold. TifTB had significantly better resistance to white mold in comparison to the most commonly grown cultivar, Georgia-06G. TifTB is also significantly more resistant to tomato spotted wilt virus in comparison to Georgia-06G. Peanut farmers are paid based on yield and grade. TifTB has very high yield and grade.

Technical Abstract: ‘TifTB’ is a runner-type peanut (Arachis hypogaea L. subsp. hypogaea var. hypogaea) cultivar released by the USDA-ARS and the Georgia Agricultural Experiment Station in 2025. TifTB was developed at the University of Georgia Coastal Plain Experiment Station, Tifton, GA. TifTB is a high oleic acid, runner market-type cultivar that also has resistance to with mold (Athelia rolfsii) and resistance to spotted wilt caused by Tomato spotted wilt tospovirus (TSWV). The original population was developed by crossing ‘Georgia-07W x MAS 7. MAS 7 is a high oleic, nematode susceptible breeding line selected from the cross of ‘Florida-07’ x [‘Tifguard’ x Florida-07]. Marker assisted selection was used in the development of TifTB to select for the high oleic to linoleic (O/L) characteristic. TifTB exhibited a higher level of resistance to white mold in comparison to ‘Georgia-12Y’ the standard resistant check. Farmers who want to grow a high oleic, runner-type peanut cultivar with resistance to white mold and TSWV also need the highest yield and grade for maximum economic return. When tested in fields without severe white mold pressure, TifTB exhibited yields that were at least similar to other currently grown peanut cultivars. When tested in fields with severe white mold pressure, TifTB exhibited yield that was at least equivalent to Georgia-12Y, and significantly higher than susceptible cultivars. TifTB has consistently exhibited high grades.
