Registration of ‘TifNV‐High O/L’ Peanut

Abstract

‘TifNV‐High O/L’ (Reg. No. CV‐132, PI 680611) 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 2014. TifNV‐High O/L was developed at the University of Georgia Coastal Plain Experiment Station, Tifton, GA. Our research objective was to combine resistance to the peanut root‐knot nematode and resistance to spotted wilt caused by Tomato spotted wilt tospovirus (TSWV) with the high oleic acid characteristic. Breeding populations were developed by hybridizing the nematode‐resistant cultivar Tifguard with the high oleic cultivar Florida‐07. Marker assisted selection was used to select for nematode resistance and the high oleic to linoleic fatty acid ratio (O/L) characteristic. TifNV‐High O/L has a high level of resistance to both the peanut root‐knot nematode and TSWV, and it has a high ratio of oleic acid to linoleic acid. When tested in fields without nematode pressure, TifNV‐High O/L exhibited yields that were similar to other currently grown peanut cultivars. When tested in fields with nematode pressure, TifNV‐High O/L exhibited significantly higher yields in comparison to Georgia‐06G, a widely grown susceptible cultivar. Grade variables for TifNV‐High O/L were similar to other common peanut cultivars. Seed size and size distribution were similar to other large‐seeded runner‐type cultivars.
