Interpretive Summary: Julyprince is being released by ARS-USDA to provide an attractive, very firm peach ripening slightly after Redglobe, that is well-adapted to the Southeastern climate. It has performed well in South Carolina and Georgia and is suggested for trial wherever Redglobe is grown. One of the grandparents of Julyprince was a low-acid, slow-ripening peach from Dr. Masao Yoshida in Japan. The original seedling tree was planted at the Southeastern Fruit and Tree Nut Research Lab at Byron, GA in 1993 and selected by W.R. Okie when it first fruited in 1995. Julyprince ripens in early -mid July at Byron, about 3-10 days after Redglobe. The fruit is large, 3 inch in diameter when adequately thinned, and usually very round. Fruit is very firm and softens slowly on the tree, allowing it to be picked over a longer period than most other varieties. At Byron, fruit develops a yellow ground color early, but can be left firm on the tree another 10 days to increase size and red color. At maturity, the surface is 70-80 percent bright red with an attractive yellow ground color and little pubescence. The yellow, freestone flesh develops melting texture and good flavor as it ripens. Compared to Scarletprince it is slightly later, larger, and slightly less red. Trees bloom with Redglobe, making it adapted to the cooler areas of the Southeast.

Technical Abstract: Julyprince, previously tested as BY93P3427, is being released by ARS-USDA to provide an attractive, very firm peach ripening slightly after Redglobe, that is well-adapted to the Southeastern climate. It has performed well in South Carolina and Georgia and is suggested for trial wherever Redglobe is grown. Julyprince resulted from a cross of L75-A50-20 x BY89P2787. BY87P2787 is an open-pollinated seedling of BY86P48, which was a seedling of L72-4-20 x 7-28. L75-A50-20 (=??) and L72-4-20 (=Harvester op) were selections from Louisiana State University at Calhoun. Selection 7-28 (=Koyohakuto x Okubo) was a low-acid, "stony hard" peach from Dr. Masao Yoshida in Japan. The original seedling tree of BY93P3427 was planted at the Southeastern Fruit and Tree Nut Research Lab at Byron, GA in 1993 and selected by W.R. Okie when it first fruited in 1995. Julyprince ripens in early -mid July at Byron, about 3-10 days after Redglobe. The fruit is large, 7-8 centimeters (3 inch) in diameter when adequately thinned, and usually very round. Fruit is very firm and softens slowly on the tree, allowing it to be picked over a longer period than most other varieties. At Byron, fruit develops a yellow ground color early, but can be left firm on the tree another 10 days to increase size and red color. At maturity, the surface is 70-80 percent bright red with an attractive yellow ground color and little pubescence. The flesh is yellow with some red in the pit cavity, especially if allowed to hang on the tree for an extended period. The freestone fruit develops melting texture and good flavor as it ripens. Compared to Scarletprince it is slightly later, larger, and slightly less red. Trees bloom with Redglobe, requiring about 850 hours of chilling below 7(C (45(F) to break the bud rest period in climates similar to Byron.
