Abstract

A new and distinct variety of nectarine tree, denominated ‘Sunbest’, has a low winter chilling requirement estimated at 225 chill units (cu). The tree is of medium size, has a moderate vigorous and upright growth habit. It has non-showy, pink flowers and leaf glands are small, with reniform shape. Trees of ‘Sunbest’ are self-fertile and regularly bear heavy annual crops of early season fruit that are large for its ripening season. Fruit are uniformly firm and yellow with melting flesh which are semi-freestone. Fruit are oval, and uniform with substantially symmetrical shape, and have an attractive 90 to 100% bright red skin. The fruit of ‘Sunbest’ ripens about 3 to 5 days before ‘Sunraycer’ nectarine in early May at Gainesville, Fla.

Description

Botanical classification: Prunus persica.
BACKGROUND OF THE NEW VARIETY
The present invention relates to a new and distinct variety of nectarine [Prunus persica (L.) Batsch] tree adapted to a subtropical (low chill) winter climate. This new tree, named ‘Sunbest’, produces highly colored, good eating quality, semi-freestone, melting flesh fruit for fresh market in early May at Gainesville, Fla. Contrast is made to ‘Sunraycer’ (unpatented) nectarine, a standard variety, for reliable description. ‘Sunbest’ is a promising candidate for commercial success in that it has large, attractive red skin, sweet fruit that ripen evenly.
ORIGIN OF THE VARIETY
‘Sunbest’ nectarine tree (genotype) originated in a cultivated area of the fruit breeding program at the University of Florida, located at Gainesville, Fla. where it was tested. The seed parent was ‘Sunraycer’ nectarine and the pollen parent was ‘Suncoast’ (unpatented) nectarine. ‘Sunbest’ nectarine was selected in 1994 because it exhibited yellow, melting flesh, in a large fruit with a bright red skin. It was designated and tested as Fla. 94-15n. It 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 were transmitted.
SUMMARY OF THE VARIETY
The new and distinct variety of nectarine tree bears moderately early ripening fruit, and has a low chilling dormancy requirement. ‘Sunbest’ blooms (non showy flowers) with ‘Sunraycer’ nectarine in early February at Gainesville. The estimated chilling requirement is 225 chill units, based on bloom 1 to 2 days before ‘Sunraycer’. ‘Sunbest’ nectarine tree is characterized by bright red skin fruit having firm, melting and yellow flesh. Fruit are semi-freestone and of good flavor and eating quality. The trees are vigorous, productive and regular bearing. Trees attain in two years, a height of two meters and a spread of one and a half meters at Gainesville. Terminal growth of up to a half meter annually is common on mature five-year-old trees with normal pruning to a vase shape.
The first fruit ripen in early May at Gainesville or in about 80 to 85 days from full bloom, which is about 3 to 5 days before ‘Sunraycer’. The fruit are uniformly large (about 20% larger by weight than ‘Sunraycer’) for an early-mid season nectarine. Ripe fruit have 90 to 100% solid (no stripes) red skin with a small amount of red pigment in the flesh at the tip end of the fruit, especially on trees stressed during hot, dry weather. There is no red pigment in the flesh at the pit. The flower anthers are light red to yellow, and leaf glands are reniform, common characteristics of many standard nectarine varieties.
DESCRIPTION OF THE DRAWINGS
The accompanying drawing is a color 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 shows an attractive shape and exterior coloration of four specimens of fruit above a ruler in side view, stem end view, a blossom end view, a side view showing the suture and a fruit cut longitudinally to show the pit.
DETAILED BOTANICAL DESCRIPTION
The tree, flowers, and fruit may vary in slight detail due to variations in soil type, cultural practices, and climatic condition. The potential for commercial production of fresh fruit by ‘Sunbest’ is high, due to its attractive red skin over a bright yellow ground color, large fruit of good flavor, and good firmness with even ripening throughout the fruit. The present botanical description is that of the variety grown on 5-year-old trees on ‘Flordaguard’ rootstock under the ecological conditions prevailing at Gainesville, Fla. Colors (except those in common terms) are described from “The Pantone Book of Color”, published by H. N. Abrams, Inc., N.Y. 1990.
Tree:
Ploidy.—Diploid
Size.—Trees are medium stature when trained to an open vase form.
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.
Density.—Light to medium in branching habit. Foliage density is high due to short internodes (8 to 11 nodes/10 cm shoot length). Internode length is shorter than in most standard varieties. Pruning is required to open the tree center to promote sunlight entrance for enhancing fruit color and sugar.
Form.—Semi-upright, but easily spread when pruned to vase shape.
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. Yields equivalent of 200 bushels (50 lbs. each) per acre have been obtained on 5-year-old hand thinned trees under a commercial simulated orchard culture at Gainesville. Trees annually set several times the number of fruit for a desired crop load.
Chilling requirement.—Estimated endodormancy chilling requirement is 225 chill units based on time of bloom and leafing.
Trunk:
Size.—Medium trunk diameter attaining 8 cm diameter at a height of 30 cm at the end of 3 years growth at Gainesville.
Texture.—Medium smooth, but changes to medium shaggy as tree ages.
Bark color.—Older bark gray, Chinchilla (Pantone 17-1109).
Lenticels.—Numerous (23 per 4 square inches of surface area of trunk) and small (2-5 mm length perpendicular to the trunk) with the center being yellowish brown, Medal Bronze (Pantone 17-0942).
Branches:
Size.—Strong growth of scaffold branches. Fruiting branches mostly large diameter (4 to 6 mm) and not overly numerous, resulting in strong fruiting wood. Thus, the tree growth and structure permits easier and faster winter pruning.
Texture.—Relatively smooth, numerous lenticels attaining size found on trunk and old scaffolds. Roughness increases with age.
Color.—New wood is light green, Pale Star (Pantone 12-0626); Old wood is more brown, Ash (Pantone 16-3802).
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-upright tree.
Leaves:
Size.—Medium; 13 to 17 cm length, including the petiole; 3 to 4 cm width. Measurements were made on vigorous upright shoots of summer growth.
Thickness.—Regular and average for commercial nectarine varieties.
Form.—Lanceolate.

Stipules.—Medium (equal to most commercial peach varieties), usually 2 per bud, and abscising just before leaf becomes full size in summer growth.
Arrangement.—Alternate.
Flower buds:
Hardiness.—Hardy with respect to north central Florida winters (16F minimum observed).
Abundance.—Very high due to shorter than average internode length. Most buds set fruit in absence of spring frosts and show little evidence of bud drop.
Size.—Medium, average 3.5 mm length in mid winter.
Form.—Plump, conic and free.
Surface.—Pubescent scales.
Color.—Brown, Stucco (Pantone 16-1412) in late summer.
Flowers:
Blossom period.—One to 2 days before ‘Sunraycer’ nectarine — average 50% bloom February 5 to 10 most years at Gainesville, but occurring over a 7-10 day period. Time and length of bloom are dependant on ambient temperature.
