Abstract
A new and distinct variety of peach tree, denominated ‘UFGlo’, characterized by a winter chilling requirement estimated at 400 chill units (cu). The tree is medium size, moderately vigorous, and semi-spreading in growth habit. It bears showy, pink flowers, and leaves with reniform glands. Trees of ‘UFGlo’ are self-fertile and regularly bear heavy annual crops of early season fruit that are medium size (125g) for its ripening season. Fruit are uniformly firm with non-melting white flesh. Fruit are nearly round, and uniform with substantially symmetrical shape, and have an attractive 70 to 80% red skin. The fruit of ‘UFGlo’ usually ripen 10 to 14 days before ‘UFSharp’ peach in mid-May at Gainesville, Fla.
Description
Genus and species: Prunus persica (L.) Batsch.
Variety denomination: ‘UFGlo’.
The invention relates to a new and distinct variety of peach tree, Prunus persica (L.) Batsch, named ‘UFGlo’. ‘UFGlo’ is adapted to a subtropical (moderate chill) winter climate. ‘UFGlo’ produces highly colored, white and non-melting flesh fruit with good eating quality for fresh market in mid-May at Gainesville, Fla. Contrast is made to ‘UFSharp’ peach (U.S. patent application Ser. No. 12/592,576), a standard variety, for reliable description. ‘UFGlo’ is a promising candidate for commercial success in that it has attractive red skin, sweet fruit that ripen evenly.
‘UFGlo’ originated in a cultivated area in Gainesville, Fla. ‘UFGlo’ was selected in 2002 because it exhibited white, non-melting flesh, in a medium size fruit with a bright red skin. The original tree was grafted to ‘Flordaguard’ (unpatented) rootstock and was planted in Gainesville, Fla. in 2002. There are no known effects of this standard rootstock on this scion cultivar. ‘UFGlo’ has unique tree and fruit characteristics making it worthy for commercial fresh fruit production.
‘UFGlo’ has been subsequently asexually propagated by conventional bud-grafting onto ‘Flordaguard’ rootstocks in Gainesville, Fla. The present invention has been found to retain its distinctive characteristics through successive asexual propagations.
Plant Breeder's Rights for this cultivar have not been applied for. ‘UFGlo’ has not been made publicly available or sold more than one year prior to the filing of this application.
‘UFGlo’ is a new and distinct variety of peach tree which bears white, non-melting flesh fruit of good flavor, brix, and eating quality which ripens in mid-May at Gainesville, Fla. ‘UFGlo’ blooms in late February at Gainesville, Fla. and 10 to 14 days after ‘UFSharp’. Thus, the chilling requirement for ‘UFGlo’ is estimated at 400 chill units.
‘UFGlo’ trees are vigorous, productive and without alternate bearing. ‘UFGlo’ trees attain in two years a height of two meters and a spread of one and half meters at Gainesville, Fla. Terminal growth of up to a half meter annually is common on mature 5-year-old trees of ‘UFGlo’ with normal pruning to a vase shape.
‘UFGlo’ fruit ripen the week following mid-May at Gainesville, Fla. or in about 80 days from full bloom, which is 10 to 15 days before ‘UFSharp’ ripening. The fruit of ‘UFGlo’ are uniformly medium size, averaging 130g when properly thinned to a full crop. However, ‘UFGlo’ fruit are more round than ‘UFSharp’ which has longer fruit. Ripe fruit of ‘UFGlo’ have averaged 80% red blush, but there is no red pigment in the flesh or at the pit. The flower anthers of ‘UFGlo’ are deep yellow, and leaf glands are reniform, common characteristics of many standard peach varieties. No buttons (parthenocarpy fruit) or split pits have been observed. The potential for commercial production of fresh fruit is high, due to its attractive red skin over a creamy white ground color, medium size fruit of good flavor, and good firmness with even ripening throughout the fruit.
The following are the most outstanding and distinguishing characteristics of this new cultivar when grown under normal horticultural practices in Florida.
-
- 1. Trees that bloom in late February at Gainesville, Fla. and 10 to 14 days after ‘UFSharp’.
- 2. Fruit that ripens in mid-May in Gainesville, Fla., 10 to 14 days earlier than ‘UFSharp’.
- 3. Fruit having high percentage red skin, white, non-melting, clingstone, and smooth textured flesh with good flavor, brix, firmness, and eating quality.
This new peach plant is illustrated by the accompanying photograph which shows a typical specimen of the fruit, leaf, and stem of the new variety as nearly true as it is reasonably possible to make in a color illustration of this type. The photograph was taken in May 2009.
The following detailed description defines the characteristics of ‘UFGlo’. The present botanical description is that of the variety grown at the University of Florida in Gainesville, Fla. in 2009 on ‘Flordaguard’ rootstock (second generation trees, 5 years old). The tree, flowers, and fruit of ‘UFGlo’ may vary in slight detail due to variations in soil type, cultural practices, and climatic condition. The colors (except those in common terms) are described from “The Pantone Book of Color”, published by H. N. Abrams, Inc., N.Y. 1990.
- Classification:
-
- Botanical.—Prunus persica (L.) Batsch.
- Common name.—Peach.
- Parentage.—Female parent: ‘Fla. 97-47c’ (unpatented). Male parent: Unknown, bulked pollen sample generated by combining pollen from three unselected, white-fleshed peaches heterozygous for non-melting flesh.
-
- Tree:
-
- Form.—Semi-spreading, but easily pruned to vase shape.
- Vigor.—Moderately vigorous, and must be summer and winter pruned when grown to a vase shape to keep the tree open to get strong fruiting wood in the lower center; trees respond typically to irrigation and fertilization; tree growth of 4 to 6 feet in height and 3 to 5 feet in width occurs the first growing season in the field.
- Size.—Trees are medium stature when trained to an open vase form.
- Trunk diameter (on ‘Flordaguard’ rootstock).—8 cm diameter at a height of 30 cm at the end of 3 years growth at Gainesville.
- Trunk texture.—Medium smooth, but changes to medium shaggy as tree ages.
- Trunk lenticels.—Moderate number (6 to 12 per 4 square inches of surface area of trunk) and large (6 to 12 mm length perpendicular to the trunk), grey, Sponge (Pantone 16-1118) with the center being yellowish brown, Inca Gold (Pantone 17-1048).
- Bark color.—Older bark gray, Chinchilla (Pantone 17-1109).
- Density.—Light to medium in branching habit; pruning is required to open the tree center to promote sunlight entrance for enhancing fruit color and sugar.
- Hardiness.—Hardy with respect to typical north central Florida winters.
- Bearer.—Very productive annually without alternate bearing observed; trees are self fertile and must be fruit thinned to avoid limb breakage and 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 400 chill units based on time of bloom and leafing in relation to standard varieties.
-
- Branches:
-
- Size.—Strong growth of scaffold branches; fruiting branches are mostly large diameter (4 to 7 mm) and not overly twiggy, resulting in strong fruiting wood; thus, the tree growth and structure permits easier and faster winter pruning.
- Texture.—Relatively smooth, medium size lenticels attaining size found on trunk and old scaffolds; roughness increases with age.
- Color.—New wood is light green, Green Banana (Pantone 14-0434); Old wood is brown, Macaroon (Pantone 16-1323).
- Crotch angles.—Angles are selected at 45 to near 90 degrees in first year of tree training; natural angles are within the normal range of standard varieties for a semi-spreading tree and similar to those of ‘UFSharp’.
-
- Leaves:
-
- Form.—Lanceolate.
- Apex.—Acute.
- Base.—Cuneate.
- Margin.—Serrulate, slightly undulate.
- Size.—Medium; 15 to 17 cm length, including the petiole; 33 to 37 mm width (measurements made on vigorous upright shoots of summer growth).
- Thickness.—Regular and average for commercial peach varieties.
- Surface.—Upper, glabrous; Lower, medium large veins that are pinnately netted.
- Color.—Lower surface is green, Peridot (Pantone 17-0336); upper surface is slightly darker green, Artichoke Green (Pantone 18-0125).
- Glands.—Usually 4, medium size reniform glands on lower leaf blade, and petiole; leaf glands on young leaves are light green, Leek Green (Pantone 15-0628); size averages about 1 mm in length and 0.3 mm in width.
- Petiole.—Length: Average 1 cm (0.8 to 1.2 cm). Diameter: 1.5 mm. Color: Light green, Oasis (Pantone 16-0540) on older leaves of summer. Shape: Grooved longitudinally.
- Stipules.—Medium (equal to most commercial peach varieties), usually 2 per bud, and abscising just before leaf becomes full size in summer growth; color at full size is green, Olive Green (Pantone 17-0535), but tinged with anthocyanin before abscising.
- Arrangement.—Alternate.
-
- Flower buds:
-
- Hardiness.—Hardy with respect to central Florida winters (16F minimum observed).
- Abundance.—Very high due to visually shorter than average internode length; most buds set fruit in absence of spring frosts and show little evidence of bud drop.
- Size.—Medium, average 6.0 mm length in mid winter.
- Form.—Plump, conic and free.
- Surface.—Pubescent scales.
- Color.—Brown, Stucco (Pantone 16-1412) in late summer.
-
- Flowers:
