Abstract

A new and distinct cultivar of peach tree plant named ‘UFSol’. This new cultivar has a low winter chilling requirement estimated at 200 chill units (cu). The tree is medium size, moderately vigorous, and semi-spreading in growth habit. It bears showy, light pink flowers, and leaves have reniform glands. Trees of ‘UFSol’ are self-fertile and regularly bear heavy annual crops of early season fruit that are of large size for its ripening season. Fruit are uniformly firm and yellow with non-melting, clingstone flesh. Fruit are nearly slightly oval, and uniform with a substantially symmetrical shape, have an attractive golden yellow skin. The fruit of ‘UFSol’ ripen in approximately the third week in April in Gainesville, Fla.

BACKGROUND OF THE NEW CULTIVAR

The present invention relates to a new and distinct cultivar of peach (Prunus persica (L.) Batsch) tree adapted to a subtropical (low chill) winter climate. This new tree, hereinafter referred to by the name ‘UFSol’, produces clingstone fruit with 0% red blush, of good eating quality, and that have non-melting flesh fruit for fresh market in late April in Gainesville, Fla. The new peach cultivar ‘UFSol’ is a promising candidate for commercial success in that it has large, sweet fruit with an attractive yellow peel color, and that ripen evenly and set fruit under the high night temperatures during bloom in central Florida.

‘UFSol’ peach tree (genotype) originated in a cultivated area of the fruit breeding program at the University of Florida, located in Gainesville, Fla., where it was tested. ‘UFSol’ was selected in 2009 because it exhibited tree and fruit qualities with potential for variety release. ‘UFSol’ was asexually propagated by budding onto ‘Flordaguard’ (unpatented) seedling rootstock (for root-knot nematode control) and determined to have unique tree and fruit characteristics making it worthy for commercial fresh fruit production. There are no known effects of this standard rootstock on this scion cultivar. Asexually propagated plants remained true to the original tree and all characteristics of the tree and the fruit have transmitted for two generations.

Plant Breeder's Rights for this cultivar have not been applied for. The new peach cultivar ‘UFSol’ has not been made publicly available more than one year prior to the filing of this application.

SUMMARY OF THE INVENTION

‘UFSol’ peach tree is a new and distinct variety that bears fruit that ripen in late April in Gainesville, Fla., and has a moderately low chilling dormancy requirement. ‘UFSol’ has showy light pink flowers . The estimated chilling requirement is 200 chill units, based on bloom time. ‘UFSol’ produces fruit that are clingstone and of good flavor and eating quality. The trees are vigorous, productive, and without alternate bearing. Trees attain in two years a height of two meters and a spread of one and a half meters in Gainesville, Fla. 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 of ‘UFSol’ ripen in late April in Gainesville, Fla., in about 69 days from full bloom. The fruit are uniformly large in size, averaging 133 g when properly thinned to a full crop. Ripe fruit have no red pigment in the flesh or at the pit.

Plant of the new peach cultivar ‘UFSol’ can be compared to plants of ‘UFBest’ (U.S. Plant Pat. No. 25,129), a standard peach variety. In side-by-side comparisons conducted in Gainesville, Fla., plants of the new peach cultivar ‘UFSol’ differed from plants of ‘UFBest’ in the following characteristics:

- 1. trees of ‘UFSol’ are more open than trees of ‘UFBest’;
- 2. flowers of ‘UFSol’ bloom about three to five days after those of ‘UFBest’;
- 3. first fruit of ‘UFSol’ typically ripen later than those of ‘UFBest’ (0-3 days after ‘UFBest’ in most years); and
- 4. skin of fruit of ‘UFSol’ has slightly shorter pubescence than skin of fruit of ‘UFBest’.

DETAILED BOTANICAL DESCRIPTION OF THE CULTIVAR

The following detailed description sets forth the distinctive characteristics of the new peach cultivar ‘UFSol’. The present botanical description is that of the new cultivar grown as a five-year-old trees on ‘Flordaguard’ rootstock under the ecological conditions prevailing in Gainesville, Fla. The tree, flowers, and fruit of ‘UFSol’ may vary slightly in detail due to variations in soil type, cultural practices, and climatic condition. The potential for commercial production of fresh fruit by ‘UFSol’ is high, due to its attractive yellow fruit over a bright yellow ground color in the skin, large size fruit of good flavor, and good firmness with even ripening throughout the fruit. In the following description, color references are made to “The Pantone Book of Color,” published by H. N. Abrams, Inc., N.Y. (1990), except where general terms of ordinary dictionary significance are used.

Botanical Description

Botanical classification:
- - Family.—Rosaceae.
  - Botanical name.—Prunus persica.
  - Common name.—Peach.
  - Cultivar.—‘UFSol’.
Parentage:
- - Female or seed parent.—‘UFOne’ (U.S. Plant Pat. No. 21,607).
  - Male or pollen parent.—‘AP01-02h’ (unpatented).
Plant description:
- - Type.—Tree.
  - Ploidy.—Diploid.
  - Plant form.—Semi-spreading, but easily pruned to a vase shape.
  - Plant size.—Trees are medium in stature when trained to an open vase form.
  - Vigor.—Moderately vigorous, and must be pruned in summer and winter when grown to a vase shape to keep the tree open to get strong fruiting wood in the lower center. Trees typically respond to irrigation and fertilization. Tree growth of 4-6 feet in height and 3-5 feet in width occurs in the first growing season in the field in Gainesville, Fla., where they need summer pruning.
  - Density.—Light to medium in branching habit. Pruning in summer and winter is required to open the tree center and permit sunlight entrance for enhanced fruit color and sugar content development.
  - Hardiness.—Hardy with respect to typical north central Florida winters.
  - Bearing.—Productive annually without alternate bearing observed. Trees are self-fertile and must be fruit thinned to avoid limb breakage and to obtain large fruit size. Trees annually set several times the number of fruit for a desired crop load.
  - Chilling requirement.—Estimated endodormancy chilling requirement is 200 chill units based on the time of bloom and leafing in relation to standard varieties.
  - Trunk.—Size: Medium, trunk attaining a diameter of 8 cm at a height of 30 cm at the end of four years of growth in Gainesville, Fla. Texture: Medium smooth, but changes to medium shaggy as tree ages. Bark color: Older bark is gray (Chinchilla, Pantone 17-1109). Lenticels: Size: Medium small (2-8 mm in length perpendicular to the trunk). Color: Brown (Lark, Pantone 16-1324) with the center being yellowish brown (Medal Bronze, Pantone 17-0942).
  - Branches.—Size: Strong growth of scaffold branches. Fruiting branches are mostly of large diameter (4-10 mm) and not overly twiggy, resulting in strong fruiting wood. Thus, the tree growth and structure permit easier and faster winter pruning. Texture: Relatively smooth, numerous lenticels attaining size smaller than found on the trunk and old scaffolds (small-medium in size, 5-11 mm). Roughness increases with age. Color: New wood, summer: Light green (Mellow Green, Pantone 12-0426). Old fruiting wood, winter: Brown (Cinnamon, Pantone 19-1436). Crotch angles: Angles are selected at 45° to near 90° in first year of tree training. Natural angles are within the normal range of standard varieties for a spreading tree.
Foliage:
- - Arrangement.—Alternate.
  - Size.—Medium; 15-17 cm in length, including the petiole; 3.5-3.8 cm in width. Measurements were made on vigorous upright shoots of summer growth.
