The fruit is uniformly large in size, mildly acidic and sweet in flavor, globose in shape, freestone in type, firm in texture, yellow in flesh color, and mostly red in skin color.
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 its selected seed parent, ‘Diamond Princess’ (U.S. Plant Pat. No. 7,066) peach, by producing peaches that are nearly globose in shape, freestone in type, yellow in flesh color, acidic and sweet in flavor, and mostly red in skin color, but is distinguished therefrom by requiring much less chilling hours and by producing fruit that is larger in size and that matures about ten days earlier.
