Description

Botanical designation: Interspecific Prunus species.

Variety denomination: ‘Glory Red’.

BACKGROUND OF THE VARIETY

1. 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.

2. Prior Varieties

Among the existing varieties of plum and interspecific trees, which are known to us, and mentioned herein, ‘Laroda’ Plum (non-patented), ‘Queen Ann’ Plum (non-patented), ‘Burmosa’ Plum (non-patented), ‘Flavorfall’ Interspecific (U.S. Plant Pat. No. 11,990), ‘Red Beaut’ Plum (U.S. Plant Pat. No. 2,539), ‘Mariposa’ Plum (U.S. Plant Pat. No. 111), the proprietary plumcots ‘4G1180’ and ‘42GA580’, and the proprietary apricot×peach ‘10W100’ and the proprietary interspecific seedlings ‘30M591’ and ‘160LM295’, all of the proprietary seedlings are non-patented.

STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH AND DEVELOPMENT

Not applicable.

ORIGIN OF THE VARIETY

The new and distinct interspecific tree was originated by us from crosses between the following species [Prunus salicina×(Prunus salicina×Prunus armeniaca)×(Prunus armeniaca×Prunus persica)]. It originated as a first generation seedling from the cross of our proprietary interspecific seedlings ‘30M591’ (non-patented) and ‘160LM259’ (non-patented). The seed parent ‘30M591’ (non-patented) was developed by us from multiple crosses between the following varieties; ‘Laroda’ Plum (non-patented), ‘Queen Ann’ Plum (non-patented), ‘Burmosa’ Plum (non-patented), ‘Red Beaut’ Plum (U.S. Plant Pat. No. 2,539), ‘Flavorfall’ Interspecific (U.S. Plant Pat. No. 11,990) and our proprietary plumcot ‘4G1180’ (non-patented). The pollen parent ‘160LM295’ (non-patented) was developed by us from multiple crosses of the following varieties; ‘Mariposa’ Plum (U.S. Plant Pat. No. 111), ‘Red Beaut’ Plum (U.S. Plant Pat. No. 2,539), the proprietary (non-patented) plumcot selections ‘4G1180’ and ‘42GA580’, and the proprietary peach×apricot selection ‘10W100’ (non-patented). We budded a large number of these seedlings to older ‘Nemaguard’ Rootstock (non-patented) trees to induce earlier fruit production for evaluation. Under close and careful observation the present seedling exhibited desirable fruit and tree characteristics and was selected in 2009 for additional 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 NEW VARIETY

The new and distinct variety of interspecific tree which includes [(Plum×Plumcot)×(Apricot×Peach)] is of large size, vigorous upright growth and a productive and regular bearer of large size, red flesh fruit with very good flavor and eating quality. The fruit is further characterized by having attractive dark red skin color, firm flesh with good storage and shipping quality. In comparison to its seed parent ‘30M591’ (non-patented) the fruit of the new variety is approximately 30 days later in maturity. In comparison to its pollen parent ‘160LM295’ (non-patented) the fruit of the new variety has a brighter red skin color and is approximately 20 days later in maturity. In comparison to the commercial variety ‘Flavorfall’ Interspecific (U.S. Plant Pat. No. 11,990) the fruit of the new variety has red flesh compared to yellow and is approximately 27 days earlier 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) from a 4 year old tree and the colors are as nearly true as is reasonably possible in a color representation of this type.
