Abstract
The present invention relates to a new and distinct variety of nectarine tree, Prunus persica , broadly characterized by a medium size, vigorous, hardy, self-fertile, productive and regular bearing tree. The fruit matures under the ecological conditions described in the early part of June, with first picking on Jun. 2, 2006. The fruit is uniformly large in size, acidic and sweet in flavor, globose in shape, clingstone in type, firm in texture, yellow in flesh color, and full 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 nectarine tree, substantially as illustrated and described, that is most similar to ‘Rose Bright’ (U.S. Plant Pat. No. 15,845) nectarine by producing nectarines that are very firm in texture, clingstone in type, yellow in flesh color, and full red in skin color, but is distinguished therefrom by requiring more chilling hours and by producing fruit that is larger in size, has more freckles on the apex, and matures about five days earlier.
