Peach tree named ‘Sauzee Pride’

Abstract

A new and distinct variety of peach tree. 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. Vigorous, upright tree growth.
  • 2. Production of large size, peento type fruit.
  • 3. Fruit with firm flesh, good handling and shipping qualities.
  • 4. Yellow flesh fruit with a sweet, sub-acid flavor.
  • 5. Fruit with very good flavor and eating quality.
  • 6. Heavy and regular production of fruit.

Description

Botanical classification: Prunus persica.

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 and nectarine trees, which are known to us, and mentioned herein, are ‘May Grand’ Nectarine (U.S. Plant Pat. No. 2,794), ‘Early Sun Grand’ Nectarine (U.S. Plant Pat. No. 1,420), ‘Royal Gold’ Peach (U.S. Plant Pat. No. 2,663) and ‘Saturn’ Peach (U.S. Plant Pat. No. 5,123).

STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH AND DEVELOPMENT

Not applicable.

ORIGIN OF THE VARIETY

A new and distinct variety of peach tree (Prunus persica) was originated by us in our experimental orchard located near Modesto, Calif., from seed of an open pollinated proprietary seedling with field identification number 55ZA18. The (55ZA18) seedling originated from a cross between the proprietary seedling with field identification number 207LF85 and the peento peach selection 505-13 received from the quarantine station in Beltsville. The maternal parent (207LF85) originated from crosses between ‘May Grand’ Nectarine (U.S. Plant Pat. No. 2,794), ‘Early Sun Grand’ Nectarine (U.S. Plant Pat. No. 1,420) and ‘Royal Gold’ Peach (U.S. Plant Pat. No. 2,663). A large group of these open pollinated seedlings were planted and maintained on their own root system, during which time we recognized the desirable peento fruit characteristic, (commonly referred to as saucer or doughnut shape) of the present new variety and.selected it for asexual propagation and commercialization in 2001.

ASEXUAL REPRODUCTION OF THE VARIETY

Asexual reproduction of the new and distinct variety of peach tree was by budding to ‘Nemagaurd’ 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, yellow flesh, freestone fruit with very good eating quality. The fruit is further characterized with having a slight orange-red blush, having a mild, sweet, sub-acid flavor, being peento in shape, with firm flesh and having greater handling and shipping quality than most peento peach varieties. The tree has a winter chilling requirement of approximately 750 hours at or below 45° F. and is hardy in all stone fruit growing areas of California. In comparison to its seed peento peach parent (55ZA18) the new variety is larger in size, has yellow flesh compared to white and is 4 to 5 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 7 year old tree and the colors are as nearly true as is reasonably possible in a color representation of this type.
