The U.S. Department of Agriculture, Agricultural Research Service (ARS) peach breeding program in Byron, GA is one of the few public programs that remain active in developing new peach cultivars for adaptation to the Southeastern climate and the shipping market need of the regional peach industry. The “prince” series of peach cultivars were released for this need (Okie, 1993; Okie and Layne, 2008a, 2008b; Okie et al., 1982; Okie and Reilly, 1987). Most of the cultivars produce freestone peaches that are large, high-blushed, yellow-fleshed, of normal acidity, and slow-melting. As a continuing effort, ‘Liberty Joy’ (tested as BY06P1627) was released. It requires about 650 h chill (CH) and is a reliable lower-chill alternative, ripening in late June to early July. Current commercial cultivars in the harvest window, including ‘Fireprince’, ‘Blazeprince’, ‘Scarletprince’, and ‘Redglobe’, require 850 CH and do not crop well when chill is insufficient (Chen and Beckman, 2019). ‘Liberty Joy’ produces attractive, almost full-blushed, yellow-fleshed, firm, and melting fruit. Trees are well adapted to the Southeastern climate, and they are suggested for trial wherever “prince” cultivars are grown.
