Abstract
The present invention relates to a new and distinct variety of peach tree, Prunus persica , broadly characterized by a medium to large size, vigorous, hardy, self-fertile, productive and regular bearing tree. The variety blooms during the late season and requires about 650 chilling hours. The fruit matures under the ecological conditions described in the last half of August, with first picking on Aug. 19, 2014. The fruit is uniform, large in size, globose to oblate in shape, freestone in type, firm in texture, pale yellow green in flesh color, nearly full red in skin color, and mildly sub-acidic in flavor with 17 brix typical.
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 peach tree, substantially as illustrated and described, that is most similar to ‘Glacier Princess’ (U.S. Plant Pat. No. 23,867) peach by being self-fertile and productive, by having showy flowers, and by producing peaches that are freestone in type, mostly red in skin color, white in flesh color, large in size, firm in texture, and good in flavor, but is distinguished by having a larger and more vigorous tree, by having globose instead of reniform leaf glands, by blooming about fourteen days later, by requiring more chilling hours, and by producing fruit that is lower in acid and that matures about eight days earlier.
