Registration of ‘Georgia-24NHO’ peanut

Abstract

‘Georgia-24NHO’ (Reg. no. CV-160, PI 706577) is a new high-yielding, very high-oleic, Tomato spotted wilt virus (TSWV)-resistant, and root-knot nematode (RKN) [Meloidogyne arenaria (Neal) Chitwood]-resistant, large-seeded, runner-type peanut (Arachis hypogaea L. subsp. hypogaea var. hypogaea) cultivar that was released by the Georgia Agricultural Experiment Station in 2024. It was developed at the University of Georgia, Tifton Campus. Georgia-24NHO originated from a cross made between ‘Georgia-06G’ × GA 122704. Georgia-06G is a normal-oleic, TSWV-resistant, large-seeded, runner-type peanut cultivar. GA 122704 is a high-oleic, RKN-resistant, advanced Georgia breeding line. Pedigree selection was practiced within the early segregating generations. Performance testing began in the F_4:6 generation with the advanced pure-line selection, GA 192710. During the past 3 years (2021–2023) averaged over 13 multiple location tests without nematode pressure in Georgia, Georgia-24NHO had significantly less total disease incidence than ‘Georgia-14N’. Georgia-24NHO was also found to have a larger runner seed size as compared to the smaller runner-type check cultivar, Georgia-14N. Georgia-24NHO combines high-yield, TSWV-resistance, and RKN-resistance with large seed size and the very high-oleic trait for longer shelf-life and improved oil quality of peanut and peanut products.
