Description

Botanical classification: Prunus species.
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 interspecific plum and apricot trees, which are known to us, and mentioned herein, are interspecific trees with proprietary identification numbers ‘321LH465’, plumcot ‘4G720’ and peachcot ‘10W100’, ‘King David’ Plum (non-patented) and ‘Flaming Gold’ Apricot (U.S. Plant Pat. No. 2,822).
ORIGIN OF THE VARIETY
The new and distinct variety of interspecific tree, originated from multiple crosses of Prunus salicina, Prunus armeniaca and Prunus persica, was developed by us in our experimental orchard located near Modesto, Calif. It originated from seed of an open pollinated proprietary seedling with identification number ‘321LH465’, which was developed by us from various crosses between ‘King David’ Plum (non-patented), ‘Flaming Gold’ Apricot (U.S. Plant Pat. No. 2,822) and the proprietary interspecific plumcot ‘4G720’ and the proprietary peachcot ‘10W100’. A large group of these open pollinated seedlings were planted and grown on their own root system. Under close and careful observation, one such seedling, which is the present variety, exhibited desirable tree and fruit characteristics and in 1999 was selected for asexual propagation 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 interspecific variety [Plum ×(Plum×Plumcot)] ×[Plum×(Apricot×Peach)] is of large size, vigorous, upright growth and a productive and regular bearer of large, attractive dark red fruit, with very good flavor and eating quality. The fruit is further characterized by having firm yellow flesh, a good balance between acid and sugar, with an average Brix of 17.0°. In comparison to the proprietary seed parent ‘321LH465’, the fruit is larger in size, having a dark red skin color, compared to blue and is approximately 10 days later in maturity. In comparison to the ‘King David’ Plum (non-patented), the fruit of the new variety is higher in Brix, more resistant to heat damage and approximately 8 days later in maturity.
PHOTOGRAPH OF THE VARIETY
The accompanying color photographic illustration shows typical specimens of the foliage and fruit of the present new interspecific 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) and the colors are as nearly true as is reasonably possible in a color representation of this type.
