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. Regular and productive bearer of large size fruit.
  • 3. Firm fruit with attractive red skin color.
  • 4. Fruit with very good flavor and eating quality.
  • 5. Fruit with good storage and shipping quality.

Description

Botanical designation: Prunus persica.

Variety denomination: ‘TAZ’.

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, ‘Zee Pride’ Peach (U.S. Plant Pat. No. 22,606) and our proprietary non-patented peach varieties ‘226LV474’, ‘152LT601’, ‘133LM533’, ‘243LP483’ and ‘242LP147’.

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. as a first generation cross between our proprietary non-patented peach seedling selections ‘226LV474’ and ‘152LT601’. The seed parent (226LV474) originated as a first generation cross between our proprietary non-patented peach seedling selections ‘133LM533’ and ‘243LP483’. The pollen parent (152LT601) originated as an open pollinated seedling selection from our proprietary non-patented peach seedling selection with the field identification number ‘242LP147’. A large number of these first generation seedlings were budded onto older established trees of ‘Nemaguard’ Rootstock (non-patented) to enhance earlier fruit production for evaluation. Under close and careful observation we recognized the desirable tree and fruit characteristics of the present seedling and selected it in 2010 for additional asexual propagation and commercialization.

ASEXUAL REPRODUCTION OF THE VARIETY

In 2010 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 with very good flavor and eating quality. The fruit is further characterized by having firm flesh and an attractive red skin color. In comparison to its non-patented peach seed parent ‘226LV474’ the fruit of the new variety has attractive red skin color compared to yellow and is approximately 37 days earlier in maturity. In comparison to its non-patented peach pollen parent ‘152LT601’ the new variety requires approximately 900 hours chilling at 45° F. compared to 300 hours and has a more attractive red skin color. In comparison to the commercial variety ‘Zee Pride’ Peach (U.S. Plant Pat. No. 22,606) the fruit of the new variety is larger in size and is approximately 23 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 6 year old tree and the colors are as nearly true as is reasonably possible in a color representation of this type.

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.
