Abstract

A new and distinct variety of interspecific tree (Prunus salicina×(Prunus salicina×Prunus armeniaca)); the features of the tree and its fruit are characterized with the tree budded on Nemaguard rootstock (unpatented), grown on Hanford sandy loam soil with Storie Index rating 95, in USDA Hardiness Zone 9, near Modesto, Calif., and with standard commercial cultural fruit growing practices, such as pruning, thinning, spraying, irrigation and fertilization. Its novelty consists of the following unique combination of features that are desirable in a new interspecific tree:
1. Heavy and regular production of large size fruit.
2. Fruit ripening in the late maturity season.
3. Fruit with firm flesh, good storage and shipping quality.
4. Fruit with high soluble solids, averaging 17.4° Brix.
5. Relatively uniform size of fruit throughout the tree.
6. Fruit holding firm on the tree 14 to 18 days after maturity (shipping ripe).
7. Fruit with good flavor and eating quality.
8. Fruit with an attractive garnet red skin color.
9. Vigorous, upright growth.

Description

ORIGIN OF THE VARIETY
The new and distinct variety of interspecific Prunus tree (Prunus salicina×(Prunus salicina×Prunus armeniaca) was originated by us in our experimental orchard located near Modesto, Calif., as a cross between two selected seedlings with field identification numbers 65EC752 and 4G1180. The maternal parent (65EC752) originated from an open pollinated late maturing plum seedling selection of unknown parentage. The pollen parent (4G1180) originated as a plumcot from an open pollinated Red Beaut Plum (U.S. Plant Pat. No. 2,539) tree that had been grown from budwood, which had been irradiated with cobalt. A large group of these seedlings, growing on their own root, were planted and maintained under close and careful observation by us, during which time the present variety exhibited fruit with the desirable late maturing characteristic and was selected for asexual reproduction and commercialization.
ASEXUAL REPRODUCTION OF THE VARIETY
Asexual reproduction of the new and distinct variety of interspecific tree was by budding on Nemaguard rootstock (unpatented), 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 VARIETY
The present new and distinct variety of interspecific Prunus Sp. tree (plum×plumcot) is of large size, vigorous, upright growth, and a productive and regular bearer of large, yellow flesh, clingstone fruit with good flavor and eating quality. The fruit is further characterized by being relatively uniform in size throughout the tree, having firm flesh with good storage and shipping quality, having an attractive garnet red skin color, having high soluble solids (17.4° Brix), and ripening in the late maturity season. In comparison to the fruit of the late maturing interspecific tree Flavorich (U.S. Plant Pat. No. 8,546), the fruit of the present new variety is approximately 20 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 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.
DESCRIPTION OF THE VARIETY
The following is a detailed botanical description of the new variety of interspecific tree, its flowers, foliage and fruit, as based on observations of specimens grown near Modesto, Calif., with color terminology (except those in common terms) in accordance with Reinhold Color Atlas by A.
