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 good flavor and eating quality.
    • 5. Fruit having an attractive red skin color.

Description

Botanical designation: Prunus persica.
Variety denomination: ‘April Zee’.
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, ‘Super Lady’ Peach (U.S. Plant Pat. No. 15,578), ‘Super Zee’ Peach (U.S. Plant Pat. No. 17,874) and our non-patented proprietary peach seedling selections ‘390LU304’, ‘211LK116’, ‘7LL75’, ‘53ZH1029’ and ‘37ZD706’.
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 seedlings ‘390LU304’ and ‘53ZH1029’. The seed parent (390LU304) originated as a first generation cross between the non-patented proprietary peach seedling selections with the field identification numbers ‘211LK116’ and ‘7LL75’. The pollen parent (53ZH1029) originated as a first generation cross between the non-patented proprietary peach seedling selection with the field identification number ‘37ZD706’ and ‘Super Lady’ Peach (U.S. Plant Pat. No. 15,578). A large number of these first generation crosses were budded to older trees of ‘Nemaguard’ Rootstock (non-patented) to accelerate rapid fruit production. 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 and distinct 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 good flavor and eating quality. The fruit is further characterized by having firm flesh and attractive red skin color. In comparison to its proprietary non-patented peach seed parent ‘390LU304’ the fruit of the new variety has a lower chilling requirement of 200 hours compared to 400 hours and is approximately 1 week earlier in maturity. In comparison to its proprietary non-patented peach pollen parent ‘53ZH1029’ the fruit of the new variety has better eating quality and is approximately 5 days later in maturity. In comparison to the commercial variety ‘Super Zee’ Peach (U.S. Plant Pat. No. 17,874) the fruit of the new variety is larger in size.
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 7 year old tree and the colors are as nearly true as is reasonably possible in a color representation of this type.

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.
