Technical Abstract: The Agricultural Research Service, U.S. Department of Agriculture, the University of Georgia, and the University of Florida jointly announce the naming and release of the peach cultivar Gulfcrimson, previously tested as AP01-7. Gulfcrimson originated from a 1999 cross of AP96-8 x AP98-5 and was selected and propagated in 2001 at the University of Georgia Research and Extension Center in Attapulgus, Ga. Both parents are of complex origin. Gulfcrimson is a non-melting type peach selection developed for the early season peach shipping industry. Fruit ripen 90 to 95 days from full bloom, typically in late May, usually with June Gold peach in southern Georgia. The fruit are large, ranging from 114 to 150 grams (61 to 71 millimeters in diameter). Commercially ripe fruit exhibit 80 percent red over a deep yellow to orange ground color. Fruit shape is round with a recessed tip. The flesh contains some red pigment flecks in the outer flesh on the sun-exposed side of the fruit. There is little or no red in the flesh at the pit. Flesh is firm with good sweetness and does not brown readily on bruised or cut surfaces. Flesh is clingy to the pit even when fully ripe. Pits are medium small and have little tendency to split even when crop loads are low. Leaves have small reniform glands. Flowers are showy and pink. Anthers are light red and pollen is bright yellow and abundant. Trees bloom just before Sunlite nectarine, requiring about 400 hours of chilling below 7C (45F) to break the bud rest period. Gulfcrimson has fruited well in areas where the mean daily temperature of the coldest month averages 12 to 14C. Best adaptation would be for areas and sites where Flordaking peach and Sunlite nectarine have proven reliable in production.
