Interspecific tree named ‘FLAVOR JOY’

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 having a vigorous, upright growth habit. 2. Tree being a regular and productive bearer of medium size fruit. 3. Fruit with a high degree of attractive dark red skin color. 4. Fruit with good flavor and eating quality. 5. Fruit with good storage and shipping ability.

Claims

1. A new and distinct variety of interspecific tree, substantially as illustrated and described.

Description

DESCRIPTION OF THE PHOTOGRAPH

(1) 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 6 year old tree and the colors are as nearly true as is reasonably possible in a color representation of this type.

Any variety 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.
