Registration of ‘Georgia‐22MPR’ peanut

Abstract

Abstract‘Georgia‐22MPR’ (Reg. no. CV‐153, PI 702544) is a new high‐yielding, high‐oleic medium‐large‐seeded, runner‐type peanut (Arachis hypogaea L. subsp. hypogaea var. hypogaea) cultivar resistant to Tomato spotted wilt virus (TSWV), root‐knot nematode [RKN; Meloidogyne arenaria (Neal) Chitwood], and potato leafhopper (Empoasca fabae Harris). It was released by the Georgia Agricultural Experiment Station in 2022. Georgia‐22MPR was developed at the University of Georgia, Tifton Campus. It originated from the cross ‘Georgia Greener’ × GA 082524. Georgia Greener is a normal‐oleic, TSWV‐resistant, runner‐type peanut cultivar. GA 082524 is a high‐oleic, RKN‐resistant, advanced Georgia breeding line. Pedigree selection was practiced within the early segregating generations. Performance testing began in the F4:6 generation with the advanced pure‐line selection, GA 163120. During the past 4 years (2018–2021) averaged over 27 multiple location tests without nematode pressure in Georgia, Georgia‐22MPR had significantly less TSWV and total disease incidence than ‘Georgia‐14N’. Georgia‐22MPR was also found to have a larger runner seed size as compared to the smaller runner‐type check cultivar, Georgia‐14N. Georgia‐22MPR combines high yield, TSWV resistance, leafhopper insect resistance, and RKN resistance with medium–large seed size and the high‐oleic trait for longer shelf‐life and improved oil quality of peanut and peanut products.
