'UFSun' peach [Prunus persica (L.) Batsch] is released for grower trial by the Florida Agricultural Experiment Station. Trees produce attractive, sweet tasting, yellow and non-melting flesh, semi-clingstone fruit intended for fresh use. 'UFSun' is suggested for central and south Florida from Tampa to Orlando and south of Interstate 4. It may be used to replace 'UFGold' peach in south Florida because it sets fruit more reliably at Immokalee, especially under night temperatures near and above 56 F during bloom to shuck split. Trees of 'UFSun' are estimated to require about 100 chill units. We expect 'UFSun' to be grown successfully where 'Flordaprince' and 'TropicBeauty' peaches have been grown. Fruit ripen in late April in Immokalee and in early May at Gainesville. Fruit set is good and with proper thinning (six to eight inches) attain 2 1/4 inch diameter. Fruit are 50 to 70% red over a bright yellow ground color. Eating quality is good, sweet and slightly acid with a pleasing aftertaste with no bitterness.
