1. A new and distinct variety of grapevine substantially as illustrated and described and which is somewhat remotely similar to the "Superior Seedless" grapevine from which it is derived, but from which it is distinguished principally as to novelty by producing larger, rounder berries and bunches with longer shoulders when grown under the same growing conditions and which are mature for harvesting and shipment approximately May 25 in the Coachella valley of california, or about eleven days earlier than the "Superior Seedless" grapevine and about four to eight days earlier than the grapevine of u.S. Plant Pat. No. 5,151.

The present invention relates to a new and distinct variety of grapevine which will hereinafter be denominated varietally as "Brighton 650" and more particularly to a grapevine which bears seedless berries which are larger and rounder than the berries of the "Superior Seedless" grapevine, the flesh of which is very firm and crisp and has excellent eating and shipping quality and which is mature for harvesting and shipment approximately May 25 near Thermal in the Coachella Valley of California.
The "Superior Seedless" grapevine has been of notable commercial success in producing seedless grapes ripening for harvest in the Coachella Valley of California approximately June 6. Horticultural experts, growers and others having an interest in the development of new commercial varieties of fruit are acutely aware that there is a market demand for new varieties which possess characteristics superior to existing varieties or which fit within ripening periods during which no comparable varieties are available. There are a multitude of other rather more subtle considerations which may have a direct bearing upon the commercial success of a variety. Size, coloration, flavor, sugar and acid content, holding quality, shipping quality, resistance to disease and still other criteria may influence market acceptance for any new variety.
The new and distinct variety of the present invention possesses a unique conbination of attributes which make it a particularly promising variety in that it fits well with existing commerical varieties having ripening dates over substantially contiguous time periods and otherwise has exceptional characteristics in the above-noted respects.
The present variety of grapevine hereof was discovered by the inventor in the spring of 1986 in his grape vineyard located near Thermal in the Coachella Valley of California. The applicant discovered the new variety as a sport of the "Superior Seedless" grapevine. While examining a second year planting of "Superior Seedless" grapevines on his property, he noticed that one cane on a single vine was blooming several days earlier than the remaining canes on the same vine and the surrounding grapevines in the immediate vicinity. He marked the vine of the new variety and continued to observe it throughout the growing season. As the fruit of the new variety grew and matured, the inventor observed that the fruit of the new variety was bigger and more rounded than that of the surrounding "Superior Seedless" grapevines. On May 25, 1986, the new variety was 15.5 bricks and 0.54 sugar acid content whereas it took until Jun. 6, 1986 for the fruit of the surrounding vines to reach the same sugar acid content.
The inventor took cuttings from the sport of the new variety and asexually reproducing the new variety by planting the cuttings so as to cause them to generate their own respective roots. The rooted cuttings were planted among some "Superior Seedless" grapevines and grew and trained them to fruiting grapevines. The inventor observed that the asexually reproduced grapevines of the new variety retained the same characteristics which caused the original sport to be selected with earlier blooming, larger bunches and earlier fruit maturity than the surrounding grapevines. The parent sport and propagated grapevines of the new variety were observed over the last two years and continue to evidence the same distinctive characteristics.
The grapevine of the new variety is characterized as to novelty by producing fruit having seedless berries which are individually large and round and similarly fruit in large bunches. The fruit ripens for commercial harvesting approximately May 25 and holds for continued harvest until about June 20 near Thermal in the Coachella Valley of California. The new variety is most closely similar to the "Superior Seedless" grapevine from which it was derived as a sport, but from which it is distinguished and characterized principally as to novelty by producing larger, rounder berries which are ripe for harvesting approximately eleven days earlier than those of the "Superior Seedless" grapewine. This comparison between the grapevine of the new variety and the "Superior Seedless" grapevine is based upon close observation of both varieties of the same age grown side-by-side on their own respective root stocks, under identical cultural conditions and treatments. In neither case were chemical agents applied to the varieties of grapevine.
The accompanying drawing is a color photograph of clusters of grapes of the new variety showing their appearance sufficiently mature for harvesting and shipment; several leaves showing their dorsal and ventral coloration; a typical section of vine; and several berries halved in the axial plane to display the flesh coloration thereof, all of the new variety.
Referring more specifically to the pomological details of this new and distinct variety of grapevine, the following has been observed under the ecological conditions prevailing at the grape vineyard of the inventor located near Thermal in the Coachella Valley of California. All major color code designations are by reference to the Dictionary of Color, by Maerz and Paul, Second Edition, published in 1950. Common color names are also occasionally employed.
Generally:
Vigor.--Vigorous.
Figure.--Upright; dense; hardy.
Productivity.--Very productive. From the third bud from the base of the fruiting canes and higher are usually sixty-five percent (65%) fruitful or more. There is no tendency to produce a small second crop of clusters on current season's growth.
Trunk:
Size.--Large and stocky.
Bark.--Loose and shreddy.
Canes:
Size.--Long.
Numbers.--Numerous.
Diameter.--Thick.
Pattern of growth.--Straight.

Nodes.--Size -- Enlarged.
Internodes.--Medium.
Tendrils.--Size -- Medium.
Length.--Long.
Position.--Intermittent.
Form.--Long and smooth.
Shape.--The tendrils of the new variety are mainly bifurcated. The tendrils of the grapevine of U.S. Plant Pat. No. 5,151 are both bifurcated and trifurcated.
Flowers:
Generally.--Fertile. From the third to the tenth mode where most of the fruit is borne, the new variety is very fruitful, generally from twenty percent (20%) to forty percent (40%) more fruitful than the "Superior Seedless" grapevine.
Date of bloom.--Bloom begins March 25, reaches full bloom on April 1 and last blooms April 5. This is early as compared with the `Superior Seedless` grapevine which, in side-by-side comparison, first begins to bloom April 5, reaches full bloom April 12 and last blooms April 20. The Brighton 650 grapevine of the subject invention begins blooming March 25, reaches full bloom by April 1 and last bloom is reached by April 5. As compared with the grapevine of U.S. Plant Pat. No. 5,151, the Brighton 650 grapevine has finished blooming before the grapevine of U.S. Plant Pat. No. 5,151 has started blooming. Its first bloom is April 8 and reaches full bloom on April 12. Its last bloom occurs by April 18.
