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 (non-patented), 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 consist of the following combination of desirable features:
    • 1. Fruit with an attractive red skin color.
    • 2. Fruit with mild, sweet, sub-acid flavor.
    • 3. Fruit that holds firm on the tree 8 to 10 days after maturity.
    • 4. Fruit with firm, yellow flesh, good handling and shipping qualities.
    • 5. Heavy and regular production of fruit.
    • 6. Vigorous, upright growth of the tree.

Description

BACKGROUND OF THE VARIETY Field of the Invention

In the field of plant genetics, we conduct an extensive and continuing plant-breeding program including the organization and asexual reproduction of orchard trees, and of which plums, peaches, nectarines, apricots, cherries and interspecifics are exemplary. It was against this background of our activities that the present variety of peach tree was originated and asexually reproduced by us in our experimental orchard located near Modesto, Stanislaus County, Calif.

PRIOR VARIETIES

Among the existing varieties of peach and nectarine trees, which are known to us, and mentioned herein, ‘Amparo’ Peach (U.S. Plant Pat. No. 6,472), ‘O'Henry’ Peach (U.S. Plant Pat. No. 2,964), ‘June Lady’ Peach (U.S. Plant Pat. No. 3,022) and ‘May Grand’ Nectarine (U.S. Plant Pat. No. 2,794).

STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH AND DEVELOPMENT

Not applicable.

ORIGIN OF THE VARIETY

The new variety of peach tree (Prunus persica) was originated by us in our experimental orchard located near Modesto, Calif. as an open pollinated seedling (pollen parent unknown) from seed collected from our proprietary parent labeled 226LK410. The proprietary seedling (226LK410) originated as the second filial generation seedling from the crosses of the following peaches and nectarine. The maternal parent was developed from the cross of a peach of unknown parentage with ‘Amparo’ Peach (U.S. Plant Pat. No. 6,472). The pollen parent was developed from the crosses of the following varieties, ‘O'Henry’ Peach (U.S. Plant Pat. No. 2,964), ‘June Lady’ Peach (U.S. Plant Pat. No. 3,022) and ‘May Grand’ Nectarine (U.S. Plant Pat. No. 2,794). We planted and maintained a large group of these open pollinated seedlings on their own root system. Under close and careful evaluation we recognized the desirable tree and fruit characteristics of the present late maturing variety and selected it for asexual propagation and commercialization.

ASEXUAL REPRODUCTION OF THE VARIETY

Asexual reproduction of the new and distinct variety of peach tree was by budding to ‘Nemaguard’ Rootstock (non-patented), 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 its fruit are established and transmitted through succeeding asexual propagations.

SUMMARY OF THE NEW VARIETY

The new variety of peach tree is of large size, vigorous, upright growth and a productive and regular bearer of large, firm, yellow flesh, clingstone fruit, having a mild, sweet, sub-acid flavor with excellent eating quality. The fruit is further characterized by having an attractive red skin color, being uniform in size throughout the tree and having the ability to hold firm on the tree 8 to 10 days after maturity (shipping ripe). In comparison to its ancestor ‘Amparo’ Peach (U.S. Plant Pat. No. 6,472) the fruit is larger in size and has a higher degree of attractive skin color and is approximately 50 days later in maturity, and in comparison to ‘O'Henry’ Peach (U.S. Plant Pat. No. 2,964) the fruit of the new variety ripens approximately 7 days later with a higher degree of attractive red skin color.

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 nearly true as is reasonably possible in a color representation of this type.
