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 early season and requires about 400 chilling hours. The fruit matures under the ecological conditions described in the latter part of May, with first picking on May 17, 2021. The fruit is uniform, medium to large in size, sub-acidic and very sweet in flavor, globose to oblate in shape, semi-freestone in type, firm in texture, white in flesh color, and red with freckles in skin color.
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 ‘Pearlicious I’ (U.S. Plant Pat. No. 22,758) nectarine by being self-fertile, by blooming in the early season, by having a large blossom, by having reniform leaf glands, and by producing nectarines that are white in flesh color, that are almost full red in skin color, that are firm in texture, and that are sweet and sub-acidic in flavor, but is distinguished therefrom by producing nectarines that are slightly larger in size, that are semi-freestone instead of clingstone in type, that have a sweet instead of bitter kernel, and that mature about nine days earlier.
