Abstract

A new and distinct variety of interspecific rootstock tree, grown on Handford sandy loam soil with Storie Index rating 95, in USDA Hardiness Zone 9, near Modesto, Calif., with standard commercial nursery practices. Its novelty consist of the following combination of desirable features:
    • 1. The ability to produce rootstock cuttings from dormant hardwood cuttings.
    • 2. Suitability for growing in containers for the home garden market.
    • 3. Reducing the size of mature cherry trees.
    • 4. Increase the number of rootstocks available for cherries.

Description

Botanical designation: Interspecific Prunus species.
Variety denomination: ‘NEWROOT-3’.
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 rootstocks, plum and cherry trees, which are known to us, and mentioned herein, ‘Atlas’ Rootstock (U.S. Plant Pat. No. 8,913), ‘Viking’ Rootstock (U.S. Plant Pat. No. 8,912), ‘Amazon’ Plum (U.S. Plant Pat. No. 2,043), ‘Laroda’ Plum (non-patented), ‘Queen Ann’ Plum (non-patented), ‘Royal Dawn’ Cherry (U.S. Plant Pat. No. 13,131), ‘Newroot-1’ Rootstock (U.S. Plant Pat. No. 21,723) and our proprietary selection ‘82EG198’.
STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH AND DEVELOPMENT
Not applicable.
ORIGIN OF THE VARIETY
The new and distinct variety of interspecific tree, (Prunus salicina×Prunus avium) was originated by us in our experimental orchard located near Modesto, Calif. as a first generation cross between our proprietary plum selection ‘82EG198’ and ‘Royal Dawn’ Cherry (U.S. Plant Pat. No. 13,131). The seed parent (82EG198) originated from crosses between ‘Laroda’ Plum (non-patented), ‘Queen Ann’ Plum (non-patented) and ‘Amazon’ Plum (U.S. Plant Pat. No. 2,043). A large number of these seedlings were budded on older trees of ‘Nemaguard’ Rootstock (non-patented) to induce earlier and larger branch growth to be used for rootstock cuttings to determine the asexual reproduction of these seedlings from cuttings. The seedlings that developed the most desirable rooting ability were selected for propagation to various varieties of cherries (Prunus avium). One such selection with desirable rooting ability, which is the present variety, was tested by budding and grafting and found to be compatible with various cherries ‘Craig's Crimson) Cherry (U.S. Plant Pat. No. 7,320), ‘Royal Rainier’ Cherry (U.S. Plant Pat. No. 10,790), and the non-patented cherry varieties ‘Van’, ‘Black Tartarian’, ‘Stella’, ‘Bing’, ‘Lapins’, we also budded to approximately 20 proprietary cherry seedling selections. This seedling was selected in 2000 for additional asexual propagation and commercialization.
ASEXUAL REPRODUCTION OF THE VARIETY
Asexual reproduction of the new and distinct variety of interspecific rootstock tree was by dormant hardwood cuttings, 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 rootstock tree (Plum×Cherry), which has vigorous, upright growth and the cuttings from the tree have the ability to develop roots similar to ‘Atlas’ Rootstock (U.S. Plant Pat. No. 8,913) and ‘Viking’ Rootstock (U.S. Plant Pat. No. 8,912) when planted directly into the field. The present new variety of interspecific rootstock is further characterized by the rapid rooting of its cuttings, allowing for spring budding of cherries, producing few or any root or trunk suckers. In comparison to its seed parent ‘82EG198’ the fruit of the new variety is small and non-commercial. Compared to its pollen parent ‘Royal Dawn’ Cherry (U.S. Plant Pat. No. 13,131), the leaves are smaller, more plum like and the fruit is larger in size. In comparison to ‘Newroot-1’ (U.S. Plant Pat. No. 21,723) the rootstock has slightly more dwarfing effect and is more suited to being grown in containers for the home garden market.
DESCRIPTION OF THE PHOTOGRAPH
The accompanying color photographic illustration shows typical specimens of the foliage and fruit of the present new interspecific rootstock 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 12 year old tree and the colors are as nearly true as is reasonably possible in a color representation of this type.
