Abstract

A new and distinct variety of interspecific 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. Tree having a vigorous, upright growth habit.
    • 2. Tree being a regular and productive bearer of large size, yellow flesh fruit.
    • 3. Fruit with an attractive, dark purple skin color.
    • 4. Fruit with very good flavor and eating quality.
    • 5. Fruit with good storage and shipping quality.

Description

Botanical designation: Interspecific Prunus species.
Variety denomination: ‘Sherri's Flavor’.
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 interspecific 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 interspecific trees, which are known to us, and mentioned herein, ‘Dapple Jack’ Interspecific (U.S. Plant Pat. No. 18,178), ‘Flavor Queen’ Interspecific (U.S. Plant Pat. No. 7,420) and the proprietary non-patented interspecific seedlings ‘63EG291’, ‘45GH111’ and ‘7HC244’.
STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH AND DEVELOPMENT
Not applicable.
ORIGIN OF THE VARIETY
The new and distinct variety of interspecific tree was developed by us in our experimental orchard located near Modesto, Calif. as an open pollinated seedling selection from our proprietary non-patented seedling ‘63EG291’. The seed parent (63EG291) originated as an open pollinated seedling selection from the proprietary non-patented interspecific seedling ‘45GH111’, which originated from the cross of the proprietary non-patented interspecific seedling ‘7HC244’ and ‘Flavor Queen’ Interspecific (U.S. Plant Pat. No. 7,420). A large number of these open pollinated seedlings were planted and maintained on their own root system and under close and careful observation we recognized the desirable tree and fruit characteristics of the present variety and selected it in 2000 for additional asexual propagation and commercialization.
ASEXUAL REPRODUCTION OF THE VARIETY
In 2000 asexual reproduction of the new and distinct variety of interspecific 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 interspecific tree is of large size, vigorous, upright growth and a regular and productive bearer of large size, freestone fruit with an attractive dark purple skin color. The fruit is further characterized by its firm, yellow flesh, very good flavor and eating quality with good handling and shipping ability. In comparison to its proprietary non-patented interspecific seed parent ‘63EG291’ the fruit of the new variety is approximately 42 days earlier in maturity. In comparison to the commercial variety ‘Dapple Jack’ Interspecific (U.S. Plant Pat. No. 18,178) the fruit of the new variety has dark purple skin compared to speckled red, is larger in size and is approximately 8 days earlier in maturity.
DESCRIPTION OF THE PHOTOGRAPH
The accompanying color photographic illustration shows typical specimens of the foliage and fruit of the present new interspecific 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 17 year old tree and the colors are as nearly true as is reasonably possible in a color representation of this type.

Any variety 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 interspecific 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.
