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) Vigorous, upright tree growth.
    • 2) Heavy and regular bearer of medium size fruit.
    • 3) Fruit with very good flavor and eating quality.
    • 4) Fruit with good handling and shipping quality.
    • 5) Fruit with an average Brix of 17.8° with a good balance between acid and sugar.

Description

Botanical classification: Interspecific Prunus species.
Variety denomination: ‘Sweet Pixzee 2’.
BACKGROUND OF THE VARIETY
1. 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.
2. Prior Varieties
Among the existing varieties of cherry and interspecific species, which are known to us, and mentioned herein, ‘Tri-Lite’ Interspecific (U.S. Plant Pat. No. 8,393), the proprietary cherry selection ‘101EB486’ (non-patented) and the proprietary non-patented interspecific selections ‘178LM74’, ‘125LE383’ and ‘5ZA500’.
STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH AND DEVELOPMENT
Not applicable.
ORIGIN OF THE VARIETY
The new and distinct variety of interspecific tree [(Prunus salicina×(Prunus salicina×Prunus armeniaca))×Prunus avium]×[Prunus salicina×(Prunus salicina×Prunus persica)] was originated by us in our experimental orchard located near Modesto, Calif. as a first generation cross between our proprietary interspecific selections; ‘178LM74’ (non-patented) and ‘5ZA500’ (non-patented). The seed parent ‘178LM74’ (non-patented) originated as a first generation cross between our proprietary interspecific seedling selection ‘125LE583’ (non-patented) and our proprietary cherry seedling selection ‘101EB486’ (non-patented). The pollen parent ‘5ZA500’ (non-patented) originated from crosses between the following; ‘Tri-Lite’ Interspecific (U.S. Plant Pat. No. 8,393) and the proprietary interspecific seedling selection ‘150LB26’ (non-patented). A large number of these first generation seedlings growing on their own root system, were budded to older trees of ‘Nemaguard’ Rootstock (non-patented) to induce earlier maturity and fruit evaluation. Under close and careful observation one such seedling exhibited desirable fruit and tree characteristics and was selected in 2005 for additional asexual propagation and commercialization.
ASEXUAL REPRODUCTION OF THE VARIETY
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 [(Plum×Plumcot)×Cherry]×[Plum×(Plum×Peach)] is of large size, vigorous, upright growth and a productive and regular bearer of medium size, yellow flesh, firm fruit with very good flavor and eating quality. The fruit is further characterized by holding firm on the tree three weeks past maturity (shipping ripe) and having good storage and shipping quality. In comparison to its seed parent ‘178LM74’ (non-patented) the fruit of the new variety has red skin color compared to yellow and is larger in size. In comparison to the pollen parent ‘5ZA500’ (non-patented) the fruit of the new variety is smaller in size and is approximately 18 days earlier in maturity. In comparison to the commercial interspecific variety ‘Dapple Supreme’ (U.S. Plant Pat. No. 16,412) the fruit of the new variety has yellow flesh compared to red, is smaller in size and is approximately 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 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 6 year old tree and the colors are as nearly true as is reasonably possible in a color representation of this type.
