‘UF Tito’ (Reg. No. CV‐107, PI 262826) and ‘UF Peace’ (Reg. No. CV‐108, PI 658214) rhizoma perennial peanut (RP; Arachis glabrata Benth.) cultivars were released by the University of Florida in 2008. After introduction into the United States in 1936 from Brazil, evaluations showed RP to be well adapted to the U.S. Gulf Coastal Plains region. UF Tito originated from Paraguay and was collected in 1959. This plant introduction resembles the plant type of ‘Florigraze’. It was identified as having high dry matter yields, highest percent pure peanut, and greatest vigor based on the amount of spread in a 10‐yr evaluation experiment. In subsequent multilocation experiments over a 5‐yr period, yields were generally equal to or higher than Florigraze. UF Peace was received in Florida in 1986 from Charles Simpson at the Texas AgriLife Research Center at Stephenville, TX, as collection no. P‐2352. The ID numbers when the material was received trace it to PI 262839, an introduction subsequently released as the germplasm Arblick. Amplified fragment length polymorphism evaluation indicates that the molecular profile of this line is different from Arblick and all other known A. glabrata germplasm. It resembles the plant type of Florigraze, and its dry matter yields and competitiveness with weedy bermudagrass [ Cynodon dactylon (L.) Pers.] are comparable. UF Peace appears to have better adaptability to the upper Coastal Plains. Both cultivars show improved field tolerance to peanut stunt virus compared with Florigraze.
