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. Tree having a vigorous, upright growth habit.
  • 2. Tree being a regular and productive bearer of large size fruit.
  • 3. Clingstone fruit with firm, yellow flesh.
  • 4. Fruit having an attractive red skin color.
  • 5. Fruit with very good flavor and eating quality.

Description

Botanical designation: Prunus persica.
Variety denomination: ‘Summer Perfection’.
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, 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.
PRIOR VARIETIES
Among the existing varieties of peach trees, which are known to us, and mentioned herein, ‘Sweet Henry’ Peach (U.S. Plant Pat. No. 16,068), ‘Summer Amelia’ Peach (U.S. Plant Pat. No. 24,777) and our proprietary non-patented nectarine seedling selection ‘170LT100’.
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 a first generation cross between our proprietary non-patented peach seedling ‘36LW277’ and ‘Sweet Henry’ Peach (U.S. Plant Pat. No. 16,068). The seed parent (36LW277) originated as an open pollinated seedling selection from our proprietary non-patented nectarine seedling selection ‘170LT100’. A large number of these first generation seedlings were planted and grown on their own root system, during which time we recognized the desirable tree and fruit characteristics of the present seedling and selected it in 2013 for additional asexual propagation and commercialization.
ASEXUAL REPRODUCTION OF THE VARIETY
In 2013 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 and distinct variety of peach tree (Prunus persica) is of large size, vigorous, upright growth and a regular and productive bearer of large size, yellow flesh, clingstone fruit with good flavor and eating quality. The fruit is further characterized by having firm flesh and attractive red skin color. In comparison to its proprietary non-patented peach seed parent ‘36LW277’ the fruit of the new variety is larger in size and is approximately 8 days earlier in maturity. In comparison to its pollen parent ‘Sweet Henry’ Peach (U.S. Plant Pat. No. 16,068) the fruit of the new variety is larger in size and has a balanced sugar and acid flavor compared to a sweet sub-acid flavor. In comparison to the commercial variety ‘Summer Amelia’ Peach (U.S. Plant Pat. No. 24,777) the fruit of the new variety is larger in size and is approximately 5 days earlier 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.
