Abstract
The present invention relates to a new and distinct variety of nectarine tree, Prunus persica , broadly characterized by a large size, vigorous, hardy, self-fertile, productive and regular bearing tree. The variety blooms during the mid season and requires about 525 chilling hours. The fruit matures under the ecological conditions described in mid to late June, with first picking on Jun. 13, 2015. The fruit is large in size, globose to slightly oblong in shape, clingstone in type, firm in texture, yellow in flesh color, full red in skin color, sweet, and sub-acidic 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 nectarine tree, substantially as illustrated and described, that is most similar to ‘Sugarine I’ (U.S. Plant Pat. No. 16,585) nectarine by being self-fertile, by having globose leaf glands, and by producing nectarines that are similar in size, firm in texture, mostly red in skin color, yellow in flesh color, nearly globose in shape, clingstone in type and excellent in flavor, but is distinguished therefrom by blooming earlier, by being a larger tree, and by producing fruit that has a bitter instead of sweet kernel and that matures about twelve days earlier.
