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:

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

Not applicable.

ORIGIN OF THE VARIETY

The present new and distinct variety of interspecificPrunustree was originated by us from multiple crossing combinations ofPrunus salicina, Prunus armeniaca, Prunus persicavar.nucipersicaandPrunus persica. It was originated by us in our experimental orchard located near Modesto, Calif. as a first generation cross between the proprietary interspecific seedling selection with the field identification number ‘257LK9’ (non-patented) and ‘Dapple Fire’ Interspecific (U.S. Plant Pat. No. 12,409). The seed parent ‘257LK9’ (non-patented) originated from crosses of the following varieties; ‘Friar’ Plum (non-patented), our proprietary plum seedlings ‘27EB180’ (non-patented), ‘67GC150’ (non-patented), ‘26GB440’ (non-patented), ‘117GD279’ (non-patented) and our proprietary plumcot seedling ‘4G1180’ (non-patented). A large number of these first generation crosses were planted and grown on their own root system. Under close and careful observation one seedling, which is the present variety, exhibited desirable tree and fruit characteristics and was selected in 2002 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 new and distinct variety of interspecific tree [(Plum×Plumcot)×(Plum×Plum Nectarine))×(Peach×Plum Peach)] is of large size, semi-spreading growth and a regular and productive bearer of medium to large size fruit with good flavor and eating quality. The fruit is further characterized by having a very dark red skin color, being clingstone with firm flesh and an average Brix of 22.5°. In comparison to its seed parent ‘257LK9’ interspecific (non-patented) the fruit of the new variety has sweeter flesh flavor and is approximately 60 days later in maturity. In comparison to its pollen parent ‘Dapple Fire’ Interspecific (U.S. Plant Pat. No. 12,409) the new variety has a darker red skin color, yellow flesh instead of dark red, pubescent skin compared to glabrous skin and is approximately 63 days later in maturity. In comparison to the commercial variety ‘Black Kat’ Interspecific (U.S. Plant Pat. No. 13,134) the fruit of the new variety has a darker yellow flesh color, pubescent skin compared to glabrous skin, a more elongated shape and is approximately 3 days earlier in maturity.
