Abstract

A new and distinct variety of interspecific tree [Prunus salicina×(Prunus salicina×Prunus armeniaca)]. 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. Heavy and regular fruit production.
    • 2. Producing fruit ripening in the late maturity season.
    • 3. Fruit with firm flesh, good handling and storage quality.
    • 4. The tree having vigorous, upright growth.
    • 5. Fruit having firm, reddish yellow flesh with very good flavor and eating quality.
    • 6. Fruit with high soluble solids (Brix) averaging 18.2°.

Description

Latin name of the Genus and Species of the Plant Claimed: [Prunus salicina×(Prunus salicina×Prunus armeniaca)].
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 plum trees, which are known to us, and mentioned herein, are ‘Queen Ann’ Plum (non-patented), ‘Casselman’ Plum (non-patented), ‘King David’ Plum (non-patented), and ‘Red Beaut’ Plum (U.S. Plant Pat. No. 2,539).
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)] was originated by us in our experimental orchard, located near Modesto, Calif., as a first generation cross between 2 proprietary parents with field identification numbers ‘57RC99’ and ‘4G1180’. The maternal parent (57RC99) originated from crosses between the following plums, ‘King David’ Plum (non-patented), ‘Queen Ann’ Plum (non-patented) and ‘Casselman’ Plum (non-patented). The paternal parent being the plumcot ‘4G1180’ originated as a selected seedling from open pollinated ‘Red Beaut’ Plum (U.S. Plant Pat. No. 2,539) seed. A large number of seedlings from this first generation cross were budded to older trees of ‘Nemaguard’ Rootstock (non-patented), to accelerate rapid fruit production for evaluation. Under close and careful observation, one such seedling exhibited desirable tree growth and fruit characteristics and was selected in 1996 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 variety of interspecific tree (Plum×Plumcot) is of large size, vigorous, upright growth and a productive and regular bearer of medium size, clingstone fruit with reddish yellow flesh, very good flavor and eating quality. The fruit is further characterized by having an attractive reddish maroon skin color, being relatively uniform in size throughout the tree, holding firm on the tree for approximately 3 weeks after maturity (shipping ripe) and having good handling and shipping quality. In comparison to the grandparent ‘Casselman’ Plum (non-patented), the variety to which the instant cultivar is most similar to, the fruit of the new variety is darker in color, more uniform in size and maturity, has higher soluble solids (Brix), heavier production of fruit and is approximately 10 days later in maturity. The winter chilling requirement being approximately the same for both varieties.
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.
