Abstract

A new and distinct variety of peach tree (Prunus persica). The following features of the tree and its fruit are characterized with the tree budded on ‘Nemaguard’ rootstock (unpatented), grown on Handford Sandy loam soil with Storie Index rating 95, in USDA Hardiness Zone 9, near Modesto, Calif., with standard commercial fruit growing practices, such as, pruning, thinning, spraying, irrigation and fertilization. Its novelty consists of the following unique combination of features that are desirable in a new variety:
1. Regular and heavy production of fruit.
2. Fruit with large size and good firmness.
3. Fruit having an attractive red skin color.
4. Sweet, sub-acid fruit with excellent flavor and eating quality.
5. Fruit having firm, white flesh, with good storage and shipping qualities.
6. Fruit that has the ability to remain firm on the tree 7 to 10 days after maturity (shipping ripe).

Description

ORIGIN OF THE VARIETY
The present new variety of peach tree (Prunus persica) was originated by us in our experimental orchard located near Modesto, Calif., as an open pollinated seedling from a seedling of a cross between two seedlings with field identification Nos. 36RB243 and 103ED581. The maternal parent (36RB243) originated as an open pollinated seedling from a cross between a seedling with field identification No. 16EA132 and ‘Amparo Peach’ (U.S. Plant Pat. No. 6,472. The seedling (16EA132) originated as an open pollinated seedling from a peach of unknown parentage. The pollen parent (103ED581) originated as an open pollinated seedling between a cross of two seedlings with field identification Nos. 23EA150 and 54G51. The seedling (23EA150) originated from an open pollinated ‘O'Henry’ Peach (U.S. Plant Pat. No. 2,964) seed. The seedling (54G51) originated from an open pollinated peach seedling from a peach of unknown parentage. We grew and maintained a large group of these seedlings, growing on their own root, during which time one such seedling, which is of the present variety, being especially desirable for its tree and fruit characteristics described below, was selected for asexual reproduction and commercialization.
ASEXUAL REPRODUCTION OF THE VARIETY
Asexual reproduction of the new and distinct variety of peach tree was by budding to ‘Nemaguard’ rootstock (unpatented), as performed by us in our experimental orchard located near Modesto, Calif., and shows that reproductions run true to the original tree and all characteristics of the tree and the fruit are established and transmitted through succeeding asexual propagations.
SUMMARY OF THE VARIETY
The new and distinct variety of peach tree is of large size, vigorous, upright growth, and is a productive and regular bearer of large size, white flesh freestone fruit that has good storage and shipping qualities. The fruit is further characterized by its attractive red skin color, firm flesh, sweet, sub-acid flavor and excellent eating quality, its ability to remain firm on the tree 7 to 10 days after maturity and, in comparison to ‘Summer Sweet’ Peach (U.S. Plant Pat. No. 8,070), which it resembles in firmness and flavor, the new variety is approximately 7 days later in maturity.
PHOTOGRAPH OF THE VARIETY
The accompanying color photographic illustration shows typical specimens of the foliage and fruit of the present new peach variety. The illustration shows the upper and lower surface of the leaves, an exterior and sectional view of a fruit divided in its suture plane to show flesh color, pit cavity and the stone remaining in place. The photographic illustration was taken shortly after being picked (shipping ripe) and the colors are as true as is reasonably possible in a color representation of this type.
DESCRIPTION OF THE VARIETY
The following is a detailed botanical description of the new variety of peach tree, its flowers, foliage and fruit, as based on observations of specimens grown near Modesto, Calif., with color terminology (except those in common terms) in accordance with Reinhold Color Atlas by A.
