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, productive and regular bearing tree. The fruit matures under the ecological conditions described in mid-May, with first picking on May 10, 2014. The fruit is uniformly medium in size, sweet in flavor, oblate in shape, fairly freestone in type, firm in texture, red in flesh color, very dark red in skin color, and it has a short but strongly attached stem. The variety is very useful to cross pollinate ‘Glenred’ (U.S. Plant Pat. No. 12,859).
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, oblate in shape, firm, sweet, and fairly crack resistant, but is distinguished therefrom by blooming about four days later, by possessing different s-alleles to make it useful as a cross pollinator, and by producing cherries that are somewhat smaller in size, that ripen about two days later, that are more heat tolerant, and that have a shorter stem that is more firmly attached to the fruit.
