Abstract
The present invention relates to a new and distinct variety of peach tree, Prunus persica , broadly characterized by a medium size, vigorous, hardy, self-fertile, productive and regular bearing tree. The variety blooms during the early to mid blooming season and requires about 400 chilling hours. The fruit matures under the ecological conditions described in early to mid July with the first picking on Jul. 1, 2015. The fruit is uniform, large in size, globose in shape, freestone in type, firm in texture, white in flesh color, mostly red to pink in skin color, and a tasty balance of light acid and sugar in flavor.
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 ‘Ice Queen’ peach (U.S. Plant Pat. No. 24,700) by having a vigorous tree, by having large blossoms, by being self-fertile, and by producing white flesh freestone peaches that are mostly red in skin color, globose in shape, and firm in texture, but is distinguished therefrom by having globose instead of reniform leaf glands, by requiring less chilling hours, and by producing fruit that is larger in size and that ripens about seven days earlier.
