Registration of ‘TifJumbo’ peanut

Abstract

‘TifJumbo’ (Reg. no. CV-157, PI 701814) is a virginia-type peanut (Arachis hypogaea L. subsp. hypogaea var. hypogaea) cultivar released by the USDA–ARS and the Georgia Agricultural Experiment Station in 2021. TifJumbo was developed at the University of Georgia Coastal Plain Experiment Station, Tifton, GA. Our research objective was to develop a high oleic acid, virginia market-type cultivar that also has resistance to the peanut root-knot nematode [Meloidogyne arenaria (Neal) Chitwood race 1] and resistance to spotted wilt caused by Tomato spotted wilt tospovirus (TSWV). Breeding populations were developed by hybridizing C1805-2-9-16 × N08082olJCT. C1805-2-9-16 is a breeding line selected from the cross of Tifguard × ‘Florida-07’. N08082olJCT is a ‘Bailey’-derived, high-oleic breeding line. Marker assisted selection was used in the development of TifJumbo to select for nematode resistance and the high oleic to linoleic (O/L) characteristic. TifJumbo has a high level of resistance to both the peanut root-knot nematode and TSWV and has a high O/L ratio. When tested in fields without nematode pressure, TifJumbo exhibited yields that were at least similar to other currently grown peanut cultivars. When tested in fields with nematode pressure, TifJumbo exhibited significantly higher yields in comparison to Bailey, a widely grown, nematode-susceptible, virginia-type cultivar. Grade variables for TifJumbo were similar to other common virginia-type peanut cultivars. Seed size and size distribution were similar to other virginia-type cultivars.
