Abstract
The present invention relates to a cherry tree, Prunus avium , and more particularly to a new and distinct variety broadly characterized by a large size, vigorous, self-sterile but very productive and regular bearing tree. The fruit matures in the early season approximately in the second week in May under the ecological conditions described, with first picking on May 9, 2000. The fruit is uniformly large in size, very sweet in flavor, very firm and crisp in texture, entirely red in skin color, virtually non-doubling and somewhat resistant to skin cracking due to rain. The variety was a first generation cross using ‘Tulare’ (U.S. Plant Pat. No. 6,407) cherry as the seed parent and ‘Brooks’ (U.S. Plant Pat. No. 6,676) cherry as the selected pollen parent.
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 similar to both its seed parent, ‘Tulare’ (U.S. Plant Pat. No. 6,407), and its pollen parent, ‘Brooks’ (U.S. Plant Pat. No. 6,676), by producing early maturing fruit that is full red in skin color, very firm in texture and virtually non-doubling, but is distinguished from ‘Tulare’ and an improvement thereon by being more vigorous in growth and by producing fruit that is larger in size, sweeter and milder in flavor, crispier in texture, and about 8 days earlier in maturing, and is distinguished from ‘Brooks’ and an improvement thereon by blooming about 7 days earlier and by producing fruit that is darker in flesh color, has a much longer stem, ripens about 4 days earlier, and is considerably more resistant to skin cracking due to rain.
