All melting flesh peach and nectarine cultivars released from the University of Florida breeding program begin with the prefixes "Florda" and "Sun," respectively, with all non-melting peach and nectarine cultivars sharing the prefix, "UF." Joint releases by the University of Florida, the USDA, and the University of Georgia have the prefix, "Gulf."

Rootstock: All stone fruit grown in Florida are grafted to rootstock because of the presence of the peach root-knot nematode (Meloidogyne floridensis). ‘Flordaguard’ is a nematode-resistant rootstock that is currently recommended for both commercial and dooryard production. The distinctive red leaves of ‘Flordaguard’ allow growers to easily identify it in the nursery as root suckers emerge during the first 2 to 3 years after planting. 2
 
Low-chill cultivars: Low-chill peach cultivars are those that require fewer chill units (100–250 chill units) than those cultivars that originate from temperate climates. Chill units are variable across the state of Florida and decrease as one moves south in the state. The chilling unit requirement is not always related to the FDP, and some cultivars require large amounts of chilling yet have a short FDP. For example, ‘UFGlo’ requires 450 chill units yet has an FDP of 80 days, while ‘UFBest’ requires less than 150 chill units and has an FDP of 95 days. 2


 
 Chill Hour Accumulation in Florida (Below 45°F [7.2°C] Through February 10th)

Fig. 1 Chill Hour Accumulation in Florida (Below 45°F [7.2°C] Through February 10th)

There are many sources from which to gather this data, including the Florida Automated Weather Network FAWN (http://fawn.ifas.ufl.edu/). The state of Florida has several zones with different chill unit accumulations (Fig. 1) to aid in selecting apeach cultivar.  2

FDP: Early ripening ability is an important trait for Florida stone fruit cultivars. The period from fruit set to maturity, when the fruit can be harvested, is called fruit developmental period, or FDP. The FDP of current Florida peach cultivars is quite short: some of them will be mature and ready for harvest as soon as 60 days from fruit set. The FDP can vary with temperature during the growing season, with warmer temperatures compressing and cooler temperatures lengthening the FDP. Therefore, the FDP varies from season to season, and the numbers presented are averages over a number of years. 2

of Florida and Texas A&M in 1989. The medium-sized, semi-freestone fruit have yellow, melting flesh and develop 70% blush over a
yellow ground color. ‘TropicBeauty’ ripens between ‘UFSun’ and ‘UFOne’ and has a FDP of 89 days. Ripens in mid-May. Excellent flavor.
Self-pollinating. 2

150 Chill hours
'UFBeauty' peach
Fig. 5
'UFBeauty'
(U.S. Patent PP14,784)

'UFBeauty' is a Self-pollinating peach variety with a low winter chilling requirement of approximately 200 chill units (cu). Trees of 'UFBeauty' are of large size and highly vigorous with a semi-spreading growth habit. UFBeauty is one of the most disease resistant and one of the sweetest non-melting varieties. Fruit sweetens longer on the tree. Trees of 'UFBeauty' regularly bear heavy annual crops of early mid-season fruit which are medium large for its ripening season. Fruit of 'UFBeauty' are very firm with a yellow, non-melting flesh which are clingstone. Fruit of 'UFBeauty' are uniform and substantially symmetrical in shape and have an attractive 90 to 100% red skin with darker red stripes. Ripens mid May. Zone 9
First Harvest: Around April 29 near Gainesville, FL with a FDP of 82 days.Cropping of ‘UFBeauty’ has been unreliable in south Florida when night temperatures during the bloom period are higher than 57°F (14°C). 1

150 Chill hours
'UFOne' peach
Fig. 6
'UFOne'
(U.S. Patent PP21,607)

'UFOne' is a peach variety with a low winter chilling requirement of approximately 150 chill units (cu). Trees of 'UFOne' are of medium
size and moderately vigorous with a semi-spreading growth habit. Trees of 'UFOne' are self-fertile and regularly bear heavy annual
crops of early season fruit which are medium large for its mid-early ripening season. Fruit of 'UFOne' are very firm with a yellow, non-melting flesh which are semi-clingstone. Fruit of 'UFOne' are uniform and substantially symmetrical in shape and have an attractive

A standard for lowest chill and early ripening. High red skin color.
‘Flordaprince’ is a very heat resistant variety with firm yellow flesh and red blush skin that ripens in May. Self-pollinating.
‘Flordaprince’ was released by UF in 1982 and its fruit have melting flesh. It has been a standard low-chill peach cultivar worldwide and
is one of the earliest ripening. The fruit develop 80% red blush with dark red stripes over a yellow ground color. ‘Flordaprince’ fruit are large, uniformly firm, and yellow, with semi-clingstone pits. The fruit ripen about 7–10 days earlier than ‘TropicBeauty’ in Gainesville,

color. ‘Flordaglo’ fruit are early ripening, semi-clingstone, and are bacterial spot resistant. Fruit ripen in early May, approximately 78
days after full bloom. ‘Flordaglo’ fruit is ideal for backyard or u-pick operations due to the melting flesh texture and its tendency to
show bruises and abrasions easily. 2
It has pink fruit outside fruit, white inside. Requires about 200 chill hours. A sweet, low acid peach for Central Florida. Freestone.
Ripens mid-May. Self-pollinating.

'UFgold' peach
Fig. 9
'UFGold'
(U.S. Patent PP10,315)

The major advantages, of 'UFGold' are a low chilling requirement, early ripening, a non-melting flesh and an attractive skin. 'UFGold'
has fruited where the coldest month average 16 to 17C and in colder locations in the absence of spring frosts. This corresponds to
the area from Orlando to Leesburg in Florida. Full bloom generally occurs in early February, and the fruit ripens in late April to early May
in this area, about 80 days after full bloom and about five days before 'Flordaglo'. Trees are semi-spreading and are easily pruned to
a vase shape. Trees set a high number of flower buds, have few blind nodes, and exhibit little bud failure. Fruit have averaged about
110 grams and 2 1/2 inches diameter where fruit were thinned 6 to 8 inches apart. Fruit shape is nearly round and flesh contains little
red on non-stressed trees. Flesh is non-melting and clingy with a little separation from the stone when soft ripe. Pits have shown
little tendency to split even when crop loads were low. Leaves have small, reniform petiolar glands. Flowers are showy and pink.
Anthers are mostly yellow with little anthocyanin and pollen is bright yellow and abundant. Leaves and fruit are moderately resistant
to bacterial spot.
First Harvest: Around May 1 near Gainesville, FL with a FDP of 80 days. 1
