Peach tree named ‘Snow Pride’

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: the tree being a regular and productive bearer of large size fruit; the tree with vigorous, upright growth; producing fruit with an attractive red skin color; fruit with very good flavor and eating quality with a low to sub acid, mild, sweet flavor; and fruit with good storage and shipping quality.

Description

Botanical designation: Prunus persica.

Variety denomination: ‘Snow Pride’.

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, ‘September Snow’ Peach (U.S. Plant Pat. No. 8,003) and the proprietary peach seedling selections ‘237LP27’, ‘370LU525’, ‘55GF90’, ‘66EG140’, ‘32LG569’ and ‘58EG528’, all of which are non-patented.

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 seed of a first generation cross between our two proprietary non-patented peach seedling selections ‘237LP27’ and ‘370LU525’. The seed parent ‘237LP27’ (non-patented) originated from crosses between the following selections; ‘September Snow’ Peach (U.S. Plant Pat. No. 8,003) and the proprietary seedling selections ‘55GF90’ peach (non-patented) and ‘66EG140’ peach (non-patented). The pollen parent ‘370LU525’ (non-patented) originated from crosses between the following varieties; ‘Sweet September’ Peach (U.S. Plant Pat. No. 9,964) and the proprietary seedling selections ‘32LG569’ peach (non-patented), ‘58EG528’ peach (non-patented) and ‘66EG140’ peach (non-patented). A large number of these first generation seedlings were grown on their own root system. Under close and careful observation, one such seedling, which is the present variety, exhibited desirable tree and fruit characteristics and was selected in 2007 for 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 persica) is of large size, vigorous, upright growth and a productive and regular bearer of large size, clingstone fruit with low to subacid, mild, sweet flesh that has very good flavor and eating quality. The fruit is further characterized by having an attractive red skin color, firm white flesh and being relatively uniform in size. In comparison to the proprietary seed parent ‘237LP27’ (non-patented) the fruit of the new variety is larger in size and is approximately 6 days earlier in maturity. In comparison to the proprietary pollen parent ‘370LU525’ (non-patented) the fruit of the new variety has firmer flesh, more attractive red skin color and is approximately 15 days later in maturity. In comparison to the commercial variety ‘September Snow’ Peach (U.S. Plant Pat. No. 8,003) the fruit of the new variety is approximately 16 days 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 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.
