No cultivar name of record
This patent does not name the plant. Through the 1980s and early 1990s that was still common: naming every new cultivar only became standard practice as plants began to be marketed under brand names. The grant identifies this one by its number and by a written description instead.
Nothing here is missing from our records: the patent itself states no name. Where one exists we show it, and we do not invent one.
Abstract
The present invention relates to a nectarine tree and more particularly to a new and distinct variety broadly characterized by a medium size, medium vigorous, hardy, very productive and regular bearing tree. The fruit matures under the ecological conditions described in early June, with first picking on June 2, 1989, and is uniformly large in size, freestone in type, mostly red in skin color, mildly acidic and generously sweet in flavor, and firm in texture. The variety was developed as a hybridized seedling from the selected seed parent, Early Diamond (U.S. Plant Pat. No. 5,438), and an unnamed genetically dwarf peach seedling as the selected pollen parent.
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 freestone nectarine tree, substantially as illustrated and described, which most closely resembles its seed parent, Early Diamond (U.S. Plant Pat. No. 5,438), by producing fruit that is almost fully red in skin color, freestone in type, firm in texture, and excellent in flavor, but is distinguished therefrom and an improvement thereon by producing fruit that ripens two days later, that is larger in size, and that is less prone to split-pitting.
