Peach tree named ‘Summer Glory’

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 with very good flavor and eating quality. 5. Fruit having an attractive dark red skin color.

Description

Botanical designation: Prunus persica.

Variety denomination: ‘Summer Glory’.

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, ‘Sierra Rich’ Peach (U.S. Plant Pat. No. 12,391), ‘Sweet Henry’ Peach (U.S. Plant Pat. No. 16,068) and the proprietary non-patented peach seedling selections ‘358LN360’, ‘79EG632’ and ‘66EG140’.

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 selection ‘358LN360’ and ‘Sweet Henry’ Peach (U.S. Plant Pat. No. 16,068). The proprietary non-patented peach seed parent ‘358LN360’ originated from a cross between our proprietary non-patented peach seedling selections ‘79EG632’ and ‘66EG140’. We planted and maintained a large group of these first generation seedlings on their own root system, during which time one seedling, which is the present variety, exhibited desirable tree and fruit characteristics and was selected in 2013 for 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 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. The fruit is further characterized by its firm flesh, very good flavor and eating quality with good storage and shipping ability. In comparison to its seed parent (358LN360) the fruit of the new variety is approximately 21 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 approximately 40 days earlier in maturity. In comparison to the commercial variety ‘Sierra Rich’ Peach (U.S. Plant Pat. No. 12,391) the fruit of the new variety is larger in size and is approximately 8 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.

PLANT/FRUIT DISEASE RESISTANCE/SUSCEPTIBILITY

No specific testing for relative plant/fruit disease resistance/susceptibility has been designed. Under close observation during planting, growing, and harvesting of fruit, under normal cultural and growing conditions near Modesto, Calif., no particular plant/fruit disease resistance or susceptibility has been observed. Any variety or selection observed during indexing of plant characteristics with abnormal fungus, bacterial, virus or insect susceptibility is destroyed and eliminated from our breeding program. No atypical resistances/susceptibilities have been noted under normal cultural practices.

The present new variety of peach tree, its flowers, foliage and fruit herein described may vary in slight detail due to climate, soil conditions and cultural practices under which the variety may be grown. The present description is that of the variety grown under the ecological conditions prevailing near Modesto, Calif.
