ABSTRACT:
BACKGROUND OF THE NEW VARIETY
The present invention relates to a new and distinct variety of peach (
Prunus persica
(L.) Batsch) tree which is named ‘UF2000’ and, more particularly to a peach tree which produces highly colored, good eating quality, clingstone, non-melting flesh fruit which are mature for fresh market in mid-to late May at Gainesville and are produced on a tree adapted to a mild winter climate. Asexual propagation was performed at Gainesville, Fla. where the selection was made and trees were tested. Contrast is made to ‘UFGold’ (U.S. Plant Pat. No. 10,315) peach, a standard variety, for reliable description. This new variety is a promising candidate for commercial success in that it retains fruit firmness at the full flavor, tree ripe stage for 10 days on the tree.
ORIGIN OF THE VARIETY
This peach tree (genotype) originated in the fruit breeding program at the University of Florida, located at Gainesville, Fla. The seed parent was ‘Aztecgold’ (nonpatented), a non-melting flesh peach (originated as an F
2
of ‘Sunred’ nectarineבMexican Cling’ peach). The pollen parent was ‘Oro A’ (nonpatened), a non-melting flesh peach that originated as a seed importation from Brazil. ‘UF2000’ ripens mid to late May, between ‘Aztecgold’ (early June) and ‘Oro A’ (early May). ‘UF2000’ peach was selected from about 150 sibs as the 15
th
selection in 1992, and exhibited yellow, non-melting, clingstone flesh, and was designated Fla. 92-15C. It was propagated as a uniform variety through two successive standard asexual propagation by budding on ‘Flordaguard’ (nonpatented) seedling rootstock (for root-knot nematode control) and determined at Gainesville to have unique tree and fruit characteristics making it worthy for commercial fresh fruit production. There are no known effects of this rootstock on this scion cultivar.
SUMMARY OF THE VARIETY
The new and distinct variety of peach tree bears yellow, non-melting flesh fruit, and has a moderate-chilling dormancy requirement. ‘UF2000’ blooms about 10 days after ‘UFGold’ peach at Gainesville, bearing red skin, non-melting and yellow flesh fruit. The estimated chilling requirement is 300 chill units.
The present invention resulting in ‘UF2000’ peach tree is characterized by non-melting flesh fruit of excellent flavor and eating quality on a tree adapted to mild winters. The trees are vigorous, productive and regular bearing. Trees attain in two years, a height of three meters and a spread of two meters at Gainesville. Terminal growth of up to a meter annually is common on mature five-year-old trees with normal pruning to a vase shape. The first fruit ripen in mid-to late May at Gainesville or in about 95 days from full bloom which is about 15 to 18 days after ‘UFGold’. The fruit are uniformly large for an early peach. Ripe fruit have 50 to 70% of solid (no stripes) red skin with no red pigment in the flesh at the pit, but have some red pigment in the outer flesh on the sun exposed side of the fruit. The flower anthers are light red to yellow, a common characteristic of many standard peach and nectarine varieties.
