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, vigorous, hardy, productive and regular bearing tree. The fruit matures under the ecological conditions described approximately the third week in June, with first picking on June 13, 1983. The fruit is of medium size, very firm and crisp when ripe making excellent quality for keeping and shipping, and has an attractive dark red skin and a sweet, acidic flavor.
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 semi-freestone nectarine tree, substantially as illustrated and described, which most closely resembles May Grand Nectarine (U.S. Plant Pat. No. 4,791) and has fruit which ripens at the same time, but which is distinguished therefrom and is an improvement thereon in that its fruit colors earlier during ripening, and when shipping ripe has a fuller red color and is much firmer than May Grand and has a more acidic nectarine taste, and in that the pollen anthers frequently protrude out of the flower bud before the flower opens.
