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 bearer of large size fruit.
    • 2. Fruit with very good flavor and eating quality.
    • 3. Fruit with attractive red skin color.
    • 4. Fruit with good storage and shipping quality.
    • 5. Fruit maturity very late in the maturity season.

Description

Botanical designation: Interspecific Prunus species.
Variety denomination: ‘AUTUMN TREAT’.
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, 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.
PRIOR VARIETIES
Among the existing varieties of interspecifics, which are known to us, and mentioned herein, ‘Flavor Grenade’ Interspecific (U.S. Plant Pat. No. 12,097) and ‘Flavorfall’ Interspecific (U.S. Plant Pat. No. 11,990).
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 as an open pollinated seedling from seed collected from ‘Flavor Grenade’ Interspecific (U.S. Plant Pat. No. 12,097). A large number of these open pollinated seedlings were grown on their own root and under close and careful observation, one such seedling exhibited desirable tree and fruit characteristics and was selected in 1998 for 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 Prunus species tree (Plum×Plumcot), is of large size, vigorous, upright growth and a regular and productive bearer of large size, yellow flesh fruit with very good flavor and eating quality. The fruit is further characterized by having firm flesh, an attractive red skin color and by maturing very late in the season. In comparison to its seed parent ‘Flavor Grenade’ Interspecific (U.S. Plant Pat. No. 12,097) the fruit of the new variety is larger in size, completely overspread with red skin color and is approximately 84 days later in maturity. In comparison to the commercial variety ‘Flavorfall’ Interspecific (U.S. Plant Pat. No. 11,990) the fruit of the new variety is approximately 26 days later in maturity.
DESCRIPTION OF THE PHOTOGRAPH
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 14 year old tree and the colors are as nearly true as is reasonably possible in a color representation of this type.
