6. Vigorous, upright growth.

Description

ORIGIN OF THE VARIETY
The present new and distinct variety of peach tree 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 36EB86 and 9GC175. The peach seedling 36EB86 (non-patented) which is the material parent, was selected as an addition to our gene pool to be used in our fruit breeding program, originated from a second generation seedling that was selected from a cross between May Grand Nectarine (U.S. Plant Pat. No. 2,794) and a peach of unknown parentage. The paternal parent 9GC175 (non-patented), was also selected for use in our fruit breeding program, it originated from a second generation seedling of a cross between an open pollinated seedling of Early Sun Grand Nectarine (U.S. Plant Pat. No. 1,420) and Royal Gold Peach (U.S. Plant Pat. No. 2,663). A large group of these first generation seedlings, growing on their own root, were planted and maintained under close observation, during which time we recognized the desirable fruit characteristics described above and selected the present variety 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, 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 new and distinct variety of peach tree is of large size, vigorous, upright growth and a productive and regular bearer of large, firm, yellow flesh, semi-freestone fruit with excellent flavor and eating quality. The fruit is further characterized by holding firm on the tree 10 to 12 days after maturity (shipping ripe), having good handling and shipping quality, having a high degree of attractive red skin blush and having a mild, sweet, sub-acid taste. In comparison to the Sweet Gem Peach (U.S. Plant Pat. No. 7,952), which has a similar mild, sweet, sub-acid flavor, the fruit of the new variety is larger in size and is approximately one week 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 nearly 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.
