ABSTRACT:
STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR 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, 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 (
Prunus salicina
), which are known to us, and mentioned herein, ‘Laroda’ Plum (non-patented), ‘Queen Ann’ Plum (non-patented) and the Interspecific tree ‘Citation’ (U.S. Plant Pat. No. 5,112), (
Prunus salicina×Prunus persica
).
ORIGIN OF THE VARIETY
The new interspecific Prunus tree [
Prunus salicina×
(
Prunus salicina×Prunus armeniaca
)] originated in our experimental orchard, located near Modesto, Calif., as a cross between our proprietary parent labeled 33ED7 with a plumcot of unknown parentage. The maternal parent 33ED7 originated from a cross of ‘Laroda’ Plum (non-patented) with ‘Queen Ann’ Plum (non-patented). A large group of these seedlings were grown, on their own root system, under close and careful observation, during which time one seedling, which is the present variety, exhibited desirable fruit characteristics and, in 1992, 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, in 1992, to ‘Citation’ Rootstock (U.S. Plant Pat. No. 5,112), 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 (Plum×Plumcot) is of large size, vigorous, upright growth and a regular and productive bearer of medium size, yellow flesh fruit with very good flavor and eating quality. The fruit is further characterized by being relatively uniform in size throughout the tree, having firm flesh with good handling and shipping quality and maturing in the early maturity season. In comparison to one of its maternal parents,‘Laroda’ Plum (non-patented), the fruit of the new variety is more uniform in size, has flesh with uniformly yellow color, compared to the amber color with reddish bleeding near the skin and is approximately 30 days earlier in maturity.
