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 size, moderately vigorous, hardy, self-unfruitful, very productive and regular bearing tree. The fruit matures under the ecological conditions described in mid May, with first picking on May 16, 2011. The fruit is uniformly large in size, sweet in flavor, somewhat oblate in shape, clingstone in type, firm in texture, pink in flesh color, and full red in skin color.
Show the legal claimThe single numbered claim as granted — the legal text that defines what this patent covers.
I claim: 1. A new and distinct variety of cherry tree, substantially as illustrated and described, that is most similar to the ‘Glenred’ (U.S. Plant Pat. No. 12,859) cherry by being self-unfruitful, and by producing cherries that are large in size, oblate in shape, firm in texture, dark red in skin color, and sweet in flavor, but is distinguished therefrom by blooming four days later and by producing cherries that are pink instead of dark red in flesh color and that mature about eight days later.
