Interpretive Summary: The objective of this work was to develop a cultivar that is an improvement in comparison to TifNV-High O/L. Crosses were made to develop breeding populations. Marker assisted selection was used to select for nematode resistance and the high oleic to linoleic (O/L) characteristic. TifNV-HG has a high level of resistance to both the peanut root-knot nematode and TSWV and has a high ratio of oleic acid to linoleic acid. When tested in fields without nematode pressure TifNV-HG exhibited yields that were at least similar to other currently grown peanut varieties. When tested in fields with nematode pressure, TifNV-HG exhibited yield that was at least equivalent to the nematode resistant cultivars, TifNV-High O/l and Georgia-14N, and significantly higher than the susceptible check, Georgia-06G. TifNV-HG exhibited higher grade in comparison to TifNV-High O/L.

Technical Abstract: ‘TifNV-HG’ 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 2021. TifNV-HG was developed at the University of Georgia Coastal Plain Experiment Station, Tifton, GA. TifNV-HG is a high oleic acid, runner 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 C1805-617-2 x ‘Georgia-06G’. C1805-617-2 is a breeding line selected from the cross of ‘Tifguard’ x ‘Florida-07’. Marker assisted selection was used in the development of TifNV-HG to select for nematode resistance and the high oleic to linoleic (O/L) characteristic. TifNV-HG has a high level of resistance to both the peanut root-knot nematode and TSWV and has a high ratio of oleic acid to linoleic acid. When tested in fields without nematode pressure TifNV-HG exhibited yields that were at least similar to other currently grown peanut cultivars. When tested in fields with nematode pressure, TifNV-HG exhibited yield that was at least equivalent to the nematode resistant cultivars, TifNV-High O/L and Georgia-14N, and significantly higher than the susceptible check, Georgia-06G. TifNV-HG exhibited higher grade in comparison to TifNV-High O/L.
