Abstract
The present invention relates to a nectarine tree, Prunus persica, and more particularly to a new and distinct variety broadly characterized by a medium size, vigorous, hardy, self-fertile, productive and regular bearing tree. The fruit matures under the ecological conditions described approximately the second week in June, with first picking on Jun. 12, 2002. The fruit is uniformly large in size, excellent in flavor, globose in shape, clingstone in type, very firm in texture, white in flesh color, and red in skin color. The variety was developed as an open pollinated seedling of ‘Candy White’ (U.S. Plant Pat. No. 10,924) white flesh nectarine.
Show the legal claimThe single numbered claim as granted — the legal text that defines what this patent covers.
I claim: 1. A new and distinct variety of nectarine tree, substantially as illustrated and described, that is most similar to ‘June Pearl’ (U.S. Plant Pat. No. 9,360) nectarine by producing nectarines that are white in flesh color, nearly full red in skin color, clingstone in type and subacid in flavor, but is distinguished therefrom and an improvement thereon by by producing fruit that is much larger in size, somewhat sweeter in flavor, globose instead of oblong in shape, and matures about six days earlier.
