    • 2. The tree with vigorous, upright growth.
    • 3. Producing fruit with an attractive red skin color.
    • 4. Fruit with good flavor and very good eating quality.
    • 5. Fruit with good storage and shipping quality.

Description

Botanical designation: Prunus persica.
Variety denomination: ‘RICH SNOW’.
BACKGROUND OF THE VARIETY
1. 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, almonds 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.
2. Prior Varieties
Among the existing varieties of peach trees, which are known to us, and mentioned herein, ‘Snow Lady’ Peach (U.S. Plant Pat. No. 25,093) and ‘Snow Angel’ Peach (U.S. Plant Pat. No. 18,750).
STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH AND DEVELOPMENT
Not applicable.
ORIGIN OF THE VARIETY
The new and distinct variety of peach tree (Prunus persica) was developed by us in our experimental orchard located near Modesto, Calif. from open pollinated seed of ‘Snow Lady’ Peach (U.S. Plant Pat. No. 25,093). A large number of these open pollinated peach seedlings were grown and budded to older trees of ‘Nemaguard’ Rootstock (non-patented) to accelerate rapid fruit production. Under close and careful observation we recognized the desirable tree and fruit characteristics of the present variety and selected it in 2009 for additional 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 present new variety of peach tree (Prunus perisca) is of large size, vigorous, upright growth and a productive and regular bearer of medium to large size, clingstone fruit with a mild, sweet, sub-acid flavor and very good eating quality. The fruit is further characterized by having an attractive red skin color, firm, white flesh and being relatively uniform in size throughout the tree. In comparison to its seed parent ‘Snow Lady’ Peach (U.S. Plant Pat. No. 25,093) the fruit of the new variety is 6 days later in maturity and has a higher Brix 14.5° compared to 12.0°. In comparison to the commercial variety ‘Snow Angel’ Peach (U.S. Plant Pat. No. 18,750) the fruit of the new variety is approximately 16 days later in maturity.
DESCRIPTION OF THE PHOTOGRAPH
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 single 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) from a 5 year old tree and the colors are as nearly true as is reasonably possible in a color representation of this type.
