Registration of ‘Georgia‐12Y’ Peanut

Abstract

‘Georgia‐12Y’ (Reg. No. CV‐119, PI 667552) is a high‐yielding, medium‐seeded, runner‐type peanut (Arachis hypogaea L. subsp. hypogaea var. hypogaea) cultivar with resistance to Tomato spotted wilt virus and white mold or stem rot (caused by Sclerotium rolfsii Sacc.) that was released by the Georgia Agricultural Experiment Stations in 2012. It was developed at the University of Georgia, Coastal Plain Experiment Station, Tifton, GA. Georgia‐12Y originated from a cross made between ‘Georgia‐09B’ and ‘Georganic’. Pedigree selection was practiced within the early‐segregating generations. Performance testing began in the F4:6 generation with the advanced pure‐line selection, GA 072531, the experimental designation of Georgia‐12Y. During 3 yr (2009–11) averaged across 24 multilocation tests in Georgia, Georgia‐12Y had significantly higher yield and dollar value return per hectare compared with ‘Georgia‐10T’. Georgia‐12Y is most similar to Georgia‐10T, and should be another excellent cultivar for an early‐planting‐date option in the southeast U.S. peanut production area.
