The following features of the tree and its fruit are characterized with the tree budded on Nemaguard rootstock, grown on Hanford sandy loam soil with Storie Index rating 95, in USDA Hardiness Zone 9, near Modesto, Calif., and with standard commercial cultural fruit growing practices, such as, pruning, thinning, spraying, irrigation, and fertilization:
1. Heavy and regular production of large, white flesh fruit.
2. Fruit with good handling and shipping quality.
3. Mild, sub-acid, sweet fruit with excellent flavor and eating quality.
4. Relatively uniform size fruit throughout the tree.

6. Attractive fruit with a red blush over a yellowish white ground color.

Description

ORIGIN OF THE VARIETY
The present new variety was originated by us in our experimental orchard located near Modesto, Calif., as a first generation cross between two selected seedlings with field identification numbers `102ED609` (unpatented) and `105ED275` (unpatented). The maternal parent (`102ED609`) was selected for a future parent in our breeding program and originated as a selected seedling from a cross between a nectarine of unknown parentage and Redwing Peach (U.S. Plant Pat. No. 621) crossed with a seedling that originated from open pollinated `O'Henry` Peach (U.S. Plant Pat. No. 2,964) seeds. The pollen parent (`105ED275`) was selected for a future parent in our breeding program and originated from a seedling selection (parentage of Red Grand Nectarine (U.S. Plant Pat. No. 1,060)) crossed with a seedling originating from a cross of `Royal Gold` Peach (U.S. Plant Pat. No. 2,663) with `White Lady` Peach (U.S. Plant Pat. No. 5,821). A large group of these first generation seedlings, growing on their own root, were planted and maintained by us in our experimental orchard, during which time one such seedling, which is of the present variety, exhibited the distinctive desirable fruit characteristics described above and was selected for asexual propagation and commercialization .
ASEXUAL REPRODUCTION OF THE VARIETY
The new and distinct variety of peach tree was asexually reproduced by budding to Nemaguard rootstock, the standard rootstock for peaches and nectarines in California, as performed by us in our experimental orchard located near Modesto, Calif., and shows that all characteristics of the tree and its fruit run true to the original tree and are established and transmitted through succeeding asexual propagations.
SUMMARY OF THE VARIETY
The present new and distinct variety of peach tree is of large size, vigorous, upright growth; and a productive and regular bearer of large, white flesh, freestone fruit with excellent flavor and eating quality. The fruit is further characterized by having firm flesh with good handling and shipping quality, having relatively uniform, large size fruit throughout the tree and maturing in the late maturity season, approximately 18 days after `O'Henry` Peach (U.S. Plant Pat. No. 2,964).
DESCRIPTION OF THE PHOTOGRAPH
The accompanying photographic illustration shows typical specimens of the foliage and fruit of the present new fruit variety. The illustration shows the upper and lower surface of the leaves, an exterior and a sectional view of a fruit divided in the suture plane to reveal flesh coloration, pit cavity and a stone remaining in place. The photograph was taken shortly after being picked at maturity (shipping ripe) and the colors are as nearly true as is reasonably possible in a color representation of this type.
DESCRIPTION OF THE VARIETY
The following is a botanical description of our new and distinct variety of peach tree, its flowers, foliage and fruit are based on observations of specimens grown in our experimental orchard located near Modesto, Calif., with color terminology (except those in common terms) referenced to Reinhold Color Atlas by A. Kornerup and J. H. Wanscher.
Tree:
Size.--Large. Height and width are reduced to approximately 12 to 14 feet for economical harvesting of fruit.
Vigor.--Vigorous. Approximately 5 to 7 feet of growth in height and 4 to 5 feet of growth in width during the first growing season. During the first dormant season, the primary scaffolds are selected and the tree is pruned to approximately 4 to 5 feet in height and 3 to 4 feet in width. Height and width vary with type and depth of soil, cultural practices and climatic conditions.
Density.--Medium dense. Usually pruned to vase shape to allow more air and sunlight to the center of tree for enhanced color and brix of fruit.
Productivity.--Productive. Fruit set is usually 2 or more times the desired fruit for normal tree crop load and must be thinned and properly spaced to develop into desirable market fruit size.
Growth.--Upright. Under normal fruit cultural practices, the trees are pruned to a height of 12 to 14 feet for economical fruit harvesting. If the tree is left unpruned it would grow considerably larger in height and width.
