The following features of the tree and its fruit are characterized with the tree budded on ‘Nemaguard’ Rootstock (non-patented), grown on Hanford 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. Regular and productive bearer of medium size fruit.
    • 2. Vigorous, semi-spreading tree growth.
    • 3. Fruit having very good flavor and eating quality.
    • 4. Fruit with white flesh.
    • 5. Fruit with an attractive reddish pink blush.

Description

Botanical classification: Interspecific Prunus species.
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 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 apricots, plums and interspecifics, which are known to us and mentioned herein, ‘Tri-Gems’ Apricot (U.S. Plant Pat. No. 6,755), ‘Modesto’ Apricot (U.S. Plant Pat. No. 2,543), ‘Friar’ Plum (non-patented) and ‘Splash’ Interspecific (U.S. Plant Pat. No. 14,583).
ORIGIN OF THE VARIETY
The new and distinct variety of interspecific tree, [Prunus armeniaca×((Prunus salicina×(Prunus salicina×Prunus armeniaca)×(Prunus salicina×Prunus armeniaca)×Prunus armeniaca] was originated by us in our experimental orchard located near Modesto, Calif. as an open pollinated seedling selection from our proprietary interspecific seedling with the field identification number ‘9Z37-A’. The proprietary parent (9Z37-A) originated from the crosses of the following parents ‘Tri-Gems’ Apricot (U.S. Plant Pat. No. 6,755), ‘Modesto’ Apricot (U.S. Plant Pat. No. 2,543), ‘Friar’ Plum (non-patented), ‘Splash’ Interspecific (U.S. Plant Pat. No. 14,583), a proprietary plumcot with the field identification number ‘4G1180’ and a white apricot of unknown parentage. A large number of these open pollinated seedlings were budded on older trees of ‘Nemaguard’ Rootstock (non-patented), to induce earlier fruit production, one budded seedling exhibited desirable fruit and tree growth characteristics and was selected in 1998 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
A new and distinct variety of interspecific tree [Apricot×((Plum×Plumcot)×Plumcot)×Apricot] is of large size, vigorous, semi spreading growth and a productive and regular bearer of medium size, white flesh fruit with excellent eating quality. The fruit is further characterized by a slight reddish pink blush, firm flesh and being relatively uniform in size throughout the tree. In comparison to its immediate parent (9Z37-A), the fruit of the new variety has firmer flesh, higher soluble solids (Brix) and is approximately 3 days earlier 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 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) and the colors are as nearly true as is reasonably possible in a color representation of this type.
