Abstract
The present invention relates to a peach tree, Prunus persica, and more particularly to a new and distinct variety characterized by a large size, vigorous, hardy, self-fertile, productive and regular bearing tree. The fruit matures under the ecological conditions described in the first half of July, with first picking on Jul. 8, 2005. The fruit is uniformly medium in size, sub-acid and sweet in flavor, very oblate in shape, freestone in type, firm in texture, white in flesh color, and mostly red in skin color. The variety was developed as a first generation cross using ‘Red Glen’ (U.S. Plant Pat. No. 7,193) yellow flesh nectarine as the selected seed parent and an unnamed flat peach as the selected pollen parent.
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 peach tree, substantially as illustrated and described, that is most similar to ‘Saturn’ (U.S. Plant Pat. No. 5,123) peach by producing fruit that is white in flesh color, very oblate in shape, and freestone in type, but is distinguished therefrom and an improvement thereon by having a much lower chilling requirement and by producing fruit that has a higher percentage of red color, firmer in texture, and ripens about 10 days later in the Central Valley of California.
