Abstract
The present invention relates to a cherry tree, Prunus avium , and more particularly to a new and distinct variety broadly characterized by a medium to large size, vigorous, hardy, self-unfruitful, productive and regular bearing tree. The fruit matures under the ecological conditions described in mid May, with first picking on May 12, 2014. The fruit is uniformly medium to large in size, excellent in flavor with 22 to 26 brix, somewhat oblate in shape, clingstone in type, heat tolerant, very firm in texture, dark red in flesh color, dark red in skin color, and is strongly attached to a short stem.
Show the legal claimThe single numbered claim as granted — the legal text that defines what this patent covers.
We claim: 1. A new and distinct variety of cherry tree, substantially as illustrated and described, that is most similar to its seed parent, ‘Glenred’ (U.S. Plant Pat. No. 12,859) cherry, by being self-unfruitful, by having reniform glands, by being productive, and by producing fruit that is dark red in skin color, red in flesh color, somewhat oblate in shape, sweet, and fairly crack resistant, but is distinguished therefrom by blooming about four days later, by having the ability to carry and size a heavy crop that stays firm on the tree for a longer period of time, and by producing cherries that are somewhat larger in size, that are clingstone instead of semi-freestone, that are more heat tolerant, that ripen about four days later, and that have a shorter stem that is more strongly attached to the fruit.
