ABSTRACT:
STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH AND DEVELOPMENT
Not applicable.
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 almonds, apples, apricots, cherries, peaches, plums, nectarines 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, Calif.
PRIOR VARIETIES
Among the existing varieties of apricot, plum and interspecific trees, which are known to us and mentioned herein, ‘Patterson’ Apricot (U.S. Plant Pat. No. 2,877), ‘Red Beaut’ Plum (U.S. Plant Pat. No. 2,539) and the Interspecific tree ‘Flavor Supreme’ (U.S. Plant Pat. No. 6,763).
ORIGIN OF THE VARIETY
The present new variety of interspecific tree [(Plum×Plumcot)×(Apricot×(Plum×Plumcot)] was developed by us in our experimental orchard located near Modesto, Calif., as a first generation cross between proprietary lines of immediate parents, 369LD348 and 352LC74. The parentage of the maternal parent 369LD348 consists of
Prunus salicina
combined with
Prunus salicina
crossed with
Prunus armeniaca
and has in its ancestry ‘Red Beaut’ Plum. The pollen parent 352LC74 consists of
Prunus armeniaca
combined with
Prunus salicina
crossed with
Prunus armeniaca
and has in its ancestry ‘Patterson’ Apricot and Interspecific ‘Flavor Supreme’. A large number of these first generation seedlings were planted and grown on their own root system, under close and careful observation, during which time one such seedling exhibited distinct and desirable fruit characteristics and was selected in 1996 for asexual propagation and commercialization.
ASEXUAL REPRODUCTION OF THE VARIETY
Asexual reproduction was performed in 1996 of the new interspecific tree by budding to ‘Nemaguard’ Rootstock (non-patented), as performed by us in our experimental orchard located near Modesto, Calif., and shows that all characteristics of the tree and its fruit are established and transmitted through succeeding asexual propagations.
SUMMARY OF THE VARIETY
The present new variety of interspecific tree is medium to large in size, vigorous, upright growth, and is a regular and productive bearer of large size, firm, clingstone fruit with a mild sweet flavor and very good eating quality. The fruit is further characterized by being relatively uniform throughout the tree, having firm, even ripening flesh with good storage and shipping quality. In comparison to the Interspecific tree ‘Flavor Supreme’ (U.S. Plant Pat. No. 6,763), the fruit is larger in size, 8 to 9 days later in maturity and more uniform in shape and size throughout the tree. In comparison to ‘Red Beaut’ Plum (U.S. Plant Pat. No. 2,539), the fruit of the new variety is larger in size, has heavier overall production, and is approximately 20 days later in maturity.
