ABSTRACT:
Genus and species: [
Prunus salicina

Prunus salicina×Prunus armeniaca
)×(
Prunus persica×Prunus armeniaca
)×
Prunus armeniaca].
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 and interspecifics are exemplary. It was against this backgroud 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 apricot and interspecific trees, which are known to us, and mentioned herein, ‘Mariposa’ Plum (U.S. Pat. No. 111), ‘Red Beaut’ Plum (U.S. Plant Pat. No. 2,539), ‘Modesto’ Apricot (U.S. Plant Pat. No. 2,543) and ‘Geo Pride’ Interspecific (U.S. Plant Pat. No. 10,386).
STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH AND DEVELOPMENT
Not applicable.
ORIGIN OF THE VARIETY
The new and distinct interspecific tree was originated by us from crosses of the following species,
Prunus salicina, Prunus armeniaca
and
Prunus persica
. The present new variety was selected from a first generation cross between two proprietary parents with field identification numbers 288LF477 and 391LD449. The maternal parent (288LF477) originated from a cross of ‘Geo Pride’ Interspecific (U.S. Plant Pat. No. 10,386) with a proprietary interspecific parent, originating from crosses of the following species
Prunus salicina, Prunus armeniaca
and
Prunus persica
. The paternal parent (391LD449) originated as an interspecific selection from crosses of the following; ‘Modesto’ Apricot (U.S. Plant Pat. No. 2,543), proprietary plumcot (4G1180), and an apricot of unknown parentage. A large number of these first generation seedlings growing on their own root system were budded to trees of ‘Nemaguard’ Rootstock (non-patented) and under close and careful observation, one such budded tree exhibited desirable, early maturing fruit characteristics and was selected for additional asexual propagation and commercialization.
ASEXUAL REPRODUCTION OF THE VARIETY
Asexual reproduction of the new and distinct variety of interspecific tree was by budding, in 1998, 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 present new interspecific tree originated from crosses of the following species, (Plum×Plumcot×Peachcot×Apricot), [
Prunus salicina
×(

Prunus armeniaca
] is of large size, vigorous, upright growth and a regular and productive bearer of large, yellow flesh fruit with excellent flavor and eating quality. The fruit is further characterized by having firm flesh, good shipping and handling quality, being relatively uniform in size throughout the tree and maturing in the early maturity season. In comparision to the fruit of the early maturing parent ‘Red Beaut’ Plum (U.S. Plant Pat. No. 2,539), the fruit of the present variety is larger in size with heavier production and is 7 days earlier in maturity. In comparison to the fruit of the interspecfic tree ‘Geo Pride’ (U.S. Plant Pat. No. 10,386), the fruit of the new variety is larger in size and is approximately 50 days earlier in maturity.
