ABSTRACT:

BACKGROUND OF THE VARIETY
In the field of plant genetics, we conduct an exclusive 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 and interspecific trees, which are known to us, and mentioned herein, ‘Mariposa’ Plum (U.S. Plant Pat. No. 111), ‘Red Beaut’ Plum (U.S. Plant Pat. No. 2,539) and the Interspecific tree ‘Flavor Queen’ (U.S. Plant Pat. No. 7,420).
ORIGIN OF THE VARIETY
The present new variety of interspecific tree [((Plum×(PlumCot)×(PlumCot))]×[(Plum×PlumCot)] was developed by us in our experimental orchard located near Modesto, Calif., as a first generation cross between a selected seedling [field identification number 7HC244 (non-patented)] and ‘Flavor Queen’ (U.S. Plant Pat. No. 7,420). The maternal parent (7HC244) was selected for a future parent in our breeding program and originated as a seedling selection from a cross between ‘Mariposa’ Plum (U.S. Plant Pat. No. 111) with the selected plumcot [4G1180 (non-patented)] crossed with the plumcot seedling [42GA580 (non-patented)], both plumcots originated from open pollinated seed of ‘Red Beaut’ Plum (U.S. Plant Pat. No. 2,539). A large group of these first generation interspecific seedlings, growing on their own root, were planted and maintained under close and careful observation by us in our experimental orchard located near Modesto, Calif. One such seedling, which is the present variety, exhibited the distinctive desirable fruit characteristics described above was selected in 1992 for asexual propagation and commercialization.
ASEXUAL REPRODUCTION OF THE VARIETY
Asexual reproduction, in 1992, 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 charactristics of tree and the fruit are established and transmitted through succeeding asexual propagations.
SUMMARY OF THE VARIETY
Our present new and distinct variety of interspecific tree is of large size, vigorous, upright growth and is a regular and productive bearer of medium size, yellow flesh, semi-freestone fruit with excellent flavor and eating quality. The fruit is further characterized by having very firm flesh with good handling and shipping quality, having relatively uniform, medium size fruit throughout the tree and the fruit holding firm on the tree 3 weeks after maturity, the fruit having high soluble solids of 22° Brix and relatively uniform maturity throughout the tree. In comparision to the interspecific tree ‘Flavor Queen’ (U.S. Plant Pat. No. 7,420), the fruit of the new variety has firmer flesh, higher brix, and is approximately 15 days later in maturity. In comparision to the ‘Mariposa’ Plum (U.S. Plant Pat. No. 111), the flesh of the present variety is firmer with greater shipping quality, yellow compared to maroon; the skin is yellow, partially overspread with red compared to maroon and the fruit is slightly elongated compared to round. In comparision to the ‘Red Beaut’ Plum (U.S. Plant Pat. No.
2,539l ), the new variety has fruit which is larger in size, with firmer yellow flesh and is approximately
60 days later in maturity.
