ABSTRACT:
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 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 trees, which are known to us, and mentioned herein, are ‘Friar’ Plum (non-patented) ‘Red Beaut’ Plum (U.S. Plant Pat. No. 2,539).
STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH AND DEVELOPMENT
Not applicable.
ORIGIN OF THE VARIETY
The new and distinct variety of interspecific tree [(
Prunus salicina
×(
Prunus salicina×Prunus armeniaca
))×(
Prunus salicina×Prunus armeniaca
)] was originated by us in our experimental orchard, located near Modesto, Calif., as a first generation cross between our proprietary parents, with field identification numbers 29EB323 and 4G1180. The maternal parent (29EB323) originated from a cross of ‘Friar’ Plum (non-patented) with a proprietary plumcot identified as 4G1180, which was selected from open pollinated, seedlings grown from ‘Red Beaut’ Plum (U.S. Plant Pat. No. 2539), that had crossed with an apricot of unknown parentage. The paternal parent was pollen of the same proprietary plumcot (4G1180). We planted and maintained a large number of these first generation seedlings, growing on their own root system, under close observation, during which time the present new seedling exhibited distinct and desirable fruit and tree characteristics was selected in 1987 for asexual propagation and commercialization.
ASEXUAL REPRODUCTION OF THE VARIETY
Asexual reproduction of the new and distinct variety of interspecific tree was by budding, in 1990, 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 present variety of interspecific tree is of large size, upright growth and a productive and regular bearer of small to medium size, firm, yellow flesh fruit with excellent flavor and eating quality. The fruit is further characterized with being moderately juicy with a good balance between acid and sugar, holding firm on the tree after maturity for 12 to 15 days, in comparison to the ‘Red Beaut’ Plum (U.S. Plant Pat. No. 2,539), the tree has heavier production, the fruit is higher in Brix, has greater eating quality, has yellow skin color compared to red and is approximately 28 days later in maturity. In comparison to ‘Friar’ Plum (non-patented), the fruit is higher in Brix, has greater eating quality and is approximately 35 days earlier in maturity.
