Its novelty consist of the following combination of desirable features:
    • 1. Tree with a vigorous, semi-spreading growth habit.
    • 2. Tree being a regular and productive bearer of medium to large size fruit.
    • 3. Fruit with good flavor and eating quality.
    • 4. Fruit with an orange skin color and attractive red blush.
    • 5. Fruit with good storage and shipping quality.

Description

Botanical designation: Interspecific Prunus species.
Variety denomination: ‘Trinidad’.
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 trees, which are known to us, and mentioned herein, ‘Leah Cot’ Interspecific (U.S. Plant Pat. No. 21,863), ‘Betty-Cot’ Interspecific (U.S. Plant Pat. No. 22,648) and our proprietary non-patented interspecific seedling selections ‘15MA725’, ‘160LH337’ and ‘28Z198’.
STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH AND DEVELOPMENT
Not applicable.
ORIGIN OF THE VARIETY
The new and distinct interspecific tree consists of is a combination of crosses between (Prunus armeniaca and Prunus salicina). The new seedling was originated by us in our experimental orchard located near Modesto, Calif. as a first generation cross between our proprietary non-patented interspecific seedling with the field identification number ‘15MA725’ and ‘Leah Cot’ Interspecific (U.S. Plant Pat. No. 21,863). The proprietary non-patented interspecific seed parent (15MA725) originated from a cross between our proprietary non-patented apricot seedling ‘160LH337’ with our proprietary non-patented interspecific seedling ‘28Z198’. A large number of these first generation seedlings were grown and budded onto older established trees of ‘Nemaguard’ Rootstock (non-patented) to enhance earlier fruit production. Under close and careful observation, the present budded seedling exhibited desirable fruit and tree characteristics and was selected in 2009 for additional asexual propagation and commercialization.
ASEXUAL REPRODUCTION OF THE VARIETY
In 2009 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 NEW VARIETY
The present new variety of interspecific tree (Prunus armeniaca×Prunus salicina) is of large size, vigorous, semi-spreading growth and is a regular and productive bearer of medium size, yellow/orange flesh, freestone fruit with good flavor and eating quality. The fruit is further characterized by having orange skin color with an attractive red blush and having good handling and storage abilities. In comparison to its non-patented interspecific seed parent (15MA725) the fruit of the new variety is larger in size. In comparison to its pollen parent ‘Leah Cot’ Interspecific (U.S. Plant Pat. No. 21,863) the fruit of the new variety has a lower winter chilling requirement of 300 hours compared to 850 hours and is approximately 24 days earlier in maturity. In comparison to the commercial variety ‘Betty-Cot’ Interspecific (U.S. Plant Pat. No. 22,648) the fruit of the new variety has a lower winter chilling requirement of 300 hours compared to 750 hours and is approximately 10 days earlier in maturity.
DESCRIPTION OF THE PHOTOGRAPH
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) from a 7 year old tree and the colors are as nearly true as is reasonably possible in a color representation of this type.
