Interspecific tree "Honey Rich"

Description

ORIGIN OF THE VARIETY

The present new and distinctive variety of interspecific tree was originated by us in our experimental orchard located near Modesto, Calif., as a first generation cross between a selected seedling with field identification number 7HC43 and Tom Cot Apricot (U.S. Plant Pat. No. 7,034). The maternal parent (7HC43) originated from a cross between the selected seedling 87EB90 (apricot.times.plum cot) with Royal Zee Plum (U.S. Plant. Pat. No. 5,486). The selection (87EB90) originated from an open pollinated Flaming Gold Apricot (U.S. Plant Pat. No. 2,822) seedling crossed with a plum-cot seedling which originated from an open pollinated Red Beaut Plum (U.S. Plant Pat. No. 2,539) seed. We grew and maintained a large group of these first generation seedlings under close and careful observation. The present variety evidenced distinctive desirable fruit characteristics and was selected for asexual reproduction and commercialization.

ASEXUAL REPRODUCTION OF THE VARIETY

Asexual reproduction of the new and distinct variety of interspecific tree was by budding, as performed by us in our experimental orchard located near Modesto, Calif., and shows that all characteristics of the tree and its fruit run true to the original tree and are established and transmitted through succeeding asexual propagations.

SUMMARY OF THE VARIETY

The new and distinct variety of interspecific tree is of large size, vigorous, semi-spreading growth; and is a regular and productive bearer of medium size, orange flesh, freestone fruit with very good flavor and eating quality. The fruit shape and skin appearance are characteristic of an apricot with a high orange skin color. The flesh characterisitics resemble an apricot, except the flesh is firmer and meatier in texture and holds the fruit shape and flesh characteristic when fully tree ripe. The fruit is further characterized by having good balance between sugar and acid, with a high degree of soluble solids (average 15 Brix), which is higher than most commercially grown apricots in California.

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 fruit divided in its suture plane to reveal flesh color, pit cavity and the stone remaining in place. The photographic illustration was taken shortly after being picked (shipping ripe) and the colors are as nearly true as is reasonably possible in a color representation of this type.
