Abstract

A new and distinct variety of interspecific tree. The following features of the tree and its fruit are characterized with the tree budded on ‘Nemaguard’ Rootstock (non-patented), grown on Handford sandy loam soil with Storie Index rating 95, in USDA Hardiness Zone 9, near Modesto, Calif., with standard commercial fruit growing practices, such as pruning, thinning, spraying, irrigation and fertilization. Its novelty consist of the following combination of desirable features:

• • 1. Tree with a vigorous, upright growth habit.
  • 2. Regular and productive bearer of large size, yellow flesh fruit.
  • 3. Fruit with a high degree of attractive red skin color.
  • 4. Fruit with very good flavor and eating quality.
  • 5. Fruit with good handling and shipping quality.

Description

Botanical designation: Interspecitic Prunus species.

Variety denomination: ‘Rich Magic’.

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 nectarine, peach and interspecific trees, which are known to us, and mentioned herein, ‘Honey Lite’ Nectarine (U.S. Plant Pat. No. 18,400), ‘Super Lady’ Peach (U.S. Plant Pat. No. 15,578), the proprietary non-patented peach seedling selection ‘57Z684’ and the proprietary non-patented interspecific seedling selections ‘53ZA915’ and ‘53ZE476’.

STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH AND DEVELOPMENT

Not applicable.

ORIGIN OF THE VARIETY

The new and distinct variety of interspecific tree was developed by us in our experimental orchard located near Modesto, Calif. from a first generation cross between our proprietary non-patented interspecific seedling ‘53ZE476’ and ‘Honey Lite’ Nectarine (U.S. Plant Pat. No. 18,400). The seed parent (53ZE476) originated from a cross between our proprietary non-patented peach seedling ‘57Z684’ and our proprietary non-patented interspecific seedling ‘53ZA915’. A large number of these first generation seedlings were grown and budded to older trees of ‘Nemaguard’ Rootstock (non-patented) to accelerate rapid fruit production. Under close and careful observation we recognized the desirable tree and fruit characteristics of the present seedling and selected it in 2008 for additional asexual propagation and commercialization.

ASEXUAL REPRODUCTION OF THE VARIETY

In 2008 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 and distinct variety of interspecific tree is of large size, vigorous, upright growth and a regular and productive bearer of large size, yellow flesh, clingstone fruit. The fruit is further characterized by its attractive red skin color, very good flavor and eating quality with good handling and storage ability. In comparison to its non-patented interspecific seed parent (53ZE476) the fruit of the new variety has yellow flash compared to white. In comparison to its pollen parent ‘Honey Lite’ Nectarine (U.S. Plant Pat. No. 18,400) the fruit of the new variety is a peach compared to a nectarine and is approximately 10 days earlier in maturity. In comparison to the commercial variety ‘Super Lady’ Peach (U.S. Plant Pat. No. 15,578) the fruit of the new variety is larger in size and is approximately 22 days later 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.

Under close observation during planting, growing, and harvesting of fruit, under normal cultural and growing conditions near Modesto, Calif., no particular plant/fruit disease resistance or susceptibility has been observed. Any variety or selection observed during indexing of plant characteristics with abnormal fungus, bacterial, virus or insect susceptibility is destroyed and eliminated from our breeding program. No atypical resistances/susceptibilities have been noted under normal cultural practices. The present new variety of interspecific tree, its flowers, foliage and fruit herein described may vary in slight detail due to climate, soil conditions and cultural practices under which the variety may be grown. The present description is that of the variety grown under the ecological conditions prevailing near Modesto, Calif.
