Abstract
The present invention relates to an interspecific tree and more particularly to a new and distinct variety broadly characterized by a medium size, vigorous, hardy, and somewhat productive tree. The variety is self-unfruitful, blooms in the early season, and produces an abundance of blossoms and pollen. The fruit matures under the ecological conditions described during mid July, with first picking on Jul. 11, 2007, and will hang on the tree for about fifteen more days. The fruit is uniformly large in size, red mottled over a yellow background in skin color, clingstone in type, oblate in shape, red and orange yellow in flesh color, very firm and crisp in texture, and excellent in flavor.
Show the legal claimThe single numbered claim as granted — the legal text that defines what this patent covers.
1. A new and distinct variety of interspecific Prunus sp. tree, substantially as illustrated and described, that is similar to ‘Plumsweet IV’ (U.S. Plant Pat. No. 16,461) interspecific tree by being self-unfruitful and by producing fruit that is mottled in skin color, partially red in flesh color, and excellent in flavor, but is distinguished therefrom by blooming in the early season instead of mid season and by producing fruit that is oblate instead of oblong in shape, that has a less pronounced suture, and that matures about fifty days earlier.
