ABSTRACT:

FIELD OF INVENTION
In the field of plant genetics we conduct an extensive and continuing plant-breeding program including the origination and asexual reproduction of orchard trees, and of which plums, peaches, nectarines, apricots, cherries and interspecifics are exemplary. It is 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, California.
PRIOR VARIETIES
Among the existing varieties of plum and interspecific trees, which are, known to us, and mentioned herein, are ‘Friar’ Plum (non-patented), ‘Autumn Giant’ Plum (U.S. Plant Pat. No. 5,624), ‘Red Beaut’ Plum (U.S. Plant Pat. No. 2,539), Interspecific trees ‘Flavor Queen’ (U.S. Plant Pat. No. 7,420) and ‘Flavorosa’ (U.S. Plant Pat. No. 10,285).
ORIGIN OF THE VARIETY
The present new variety of interspecific [Plum×(Plum ×(PlumCot))×(PlumCot)] tree was developed by us in our experimental orchard located near Modesto, Calif., from seed of an open pollinated selected seedling [identification number 326LC131 (non-patented)], which was selected as a future parent in our breeding program. The parent 326LC131 originated as a first generation cross between two selected seedlings [field identification numbers 36ED128 (non-patented) and 7HC160 (non-patented)]. The female parent 36ED128 originated from a cross between ‘Friar’ Plum (non-patented) and ‘Autumn Giant’ Plum (U.S. Plant Pat. No. 5,624). The pollen parent 7HC160 originated as a first generation seedling from a cross of a selected seedling of an open pollinated ‘Friar’ Plum crossed with the plumcot (field identification number 4G1180 (non-patented)) which originated from a cross of ‘Red Beaut’ Plum (U.S. Plant Pat. No. 2,539) with an apricot of unknown parentage; the seedling selection from this cross was back crossed to the plumcot (4G1180). A large group of seedlings from the open pollinated interspecific tree 326LC121 were planted and maintained on their own root in our experimental orchard, during which time one seedling, which is the present variety, exhibited the distinctive desirable fruit characteristics described within and was selected in 1993 for asexual reproduction 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 VARIETY
The new and distinct variety of interspecific tree is of large size, vigorous, upright growth, a regular and productive bearer of large size, firm, clingstone fruit with excellent flavor and eating quality, having a good balance between acid and sugar with high soluble solids of 22.1° Brix. The fruit is further characterized by having a distinct flavor between plum and apricot with firm flesh, good handling and shipping quality, having relatively uniform, large size fruit throughout the tree and, in comparison to the plum selection ‘36ED128’, which also has fruit with yellow skin color, the new interspecific fruit is larger in size, has flesh that is approximately 10° higher in Brix and is approximately 3 weeks later in maturity, in the comparison to the fruit of the interspecific selection ‘7HC160’, which has fruit with a red blush over a yellow skin color, the new variety has larger size fruit, firmer flesh and is approximately 2 weeks later in maturity. In comparison to the fruit of the Interspecific tree ‘Flavor Queen’ (U.S. Plant Pat. No. 7,420), the fruit of the new variety is larger in size, has firmer flesh and is approximately 1 week later in maturity.
