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. The tree being a regular and productive bearer of large size, white flesh fruit.
    • 2. The tree with vigorous, upright growth.
    • 3. Producing fruit with an attractive dark red skin color.
    • 4. Fruit with good flavor and eating quality with a mild, sweet, sub-acid flavor.
    • 5. Fruit with good storage and shipping quality.

Description

Botanical designation: Prunus persica.

Variety denomination: ‘Snow Baby’.

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, ‘Sugar Lady’ Peach (U.S. Plant Pat. No. 7,532), ‘Rich Lady’ Peach (U.S. Plant Pat. No. 7,290), ‘Country Sweet’ Peach (U.S. Plant Pat. No. 11,090), ‘Zee Lady’ Peach (U.S. Plant Pat. No. 5,832), ‘Sweet Gem’ Peach (U.S. Plant Pat. No. 7,952), ‘Zee Diamond’ Peach (U.S. Plant Pat. No. 9,673), ‘Super Rich’ Peach (U.S. Plant Pat. No. 9,860), ‘Amparo’ Peach (U.S. Plant Pat. No. 6,472), ‘Spring Snow’ Peach (U.S. Plant Pat. No. 9,883), ‘Snow Fox’ Peach (U.S. Plant patent application Ser. No. 14/544,568), and the proprietary non-patented peach seedling selections ‘196LT639’, ‘59Z480’ and ‘35M358’.

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 with field identification numbers ‘196LT639’ and ‘35M358’. The seed parent ‘196LT639’ (non-patented) originated from crosses between ‘Sugar Lady’ Peach (U.S. Plant Pat. No. 7,532), ‘Rich Lady’ Peach (U.S. Plant Pat. No. 7,290) and the proprietary seedling selection ‘59Z480’ peach (non-patented). The pollen parent ‘35M358’ (non-patented) originated from crosses between the following varieties; ‘Sweet Gem’ Peach (U.S. Plant Pat. No. 7,952), ‘Zee Diamond’ Peach (U.S. Plant Pat. No. 9,673), ‘Super Rich’ Peach (U.S. Plant Pat. No. 9,860), ‘Country Sweet’ Peach (U.S. Plant Pat. No. 11,090), ‘Zee Lady’ Peach (U.S. Plant Pat. No. 5,832) and ‘Amparo’ Peach (U.S. Plant Pat. No. 6,472). A large number of these first generation seedlings were grown and budded on older ‘Nemaguard’ Rootstock (non-patented) to accelerate rapid fruit production for evaluation. 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 further asexual propagations and commercialization.

ASEXUAL REPRODUCTION OF THE VARIETY

In 2007 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 mild, sweet, sub-acid flavor and good eating quality. The fruit is further characterized by having an attractive dark red skin color, firm, white flesh and being relatively uniform in size throughout the tree. In comparison to the proprietary seed parent ‘196LT639’ peach (non-patented) the fruit of the new variety is larger in size and approximately 30 days later in maturity. In comparison to the proprietary pollen parent ‘35M358’ peach (non-patented) the fruit of the new variety has white compared to yellow flesh, a more attractive red skin color and is approximately 4 days earlier in maturity. In comparison to the commercial variety ‘Spring Snow’ Peach (U.S. Plant Pat. No. 9,883) the fruit of the new variety has a more attractive, darker red skin color and is approximately 9 days later in maturity. In comparison to ‘Snow Fox’ Peach (U.S. Plant patent application Ser. No. 14/544,568), which is the sister sibling of the present variety, with both being grown together on original mother tree on separate scaffolds and having the exact same cultural conditions, we found these differences; the fruit of the new variety being 4 days later in maturity, being slightly smaller in size, having a darker red skin color, and its flowers blooming 2 days later. Having a higher chilling requirement of approximately 50 hours allowing the new variety to be planted in more northern growing areas that require more chilling hours. The new variety has more areas of exposed ground color on the skin giving it a speckled appearance that ‘Snow Fox’ Peach (U.S. Plant patent application Ser. No. 14/544,568) does not exhibit.

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.
