Abstract

A new and distinct variety of Grapevine, designated ‘Arraone’, characterized by high crop yield, large bunches constantly produced, very uniform and attractive berries and bunches, and large, firm berries with bright white color.

Description

Botanical classification/cultivar denomination: Vitis sp. cultivar Arraone.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct variety of Grapevine, botanically known as Vitis sp., and hereinafter referred to by the name ‘Arraone’.

SUMMARY OF THE INVENTION

‘Arraone’ was bred by embryo rescue from the cross V 25/3×FL R47/63-229. It was asexually reproduced in Salinas, Calif., by tissue culture, emasculating seedless mother pollened with seedless father, and the seed trace rescued in tissue culture process. Observations made on ‘Arraone’ since May 1997 have shown that the unique features of this new Grapevine are stable and reproduced true to type in successive generations.

The new variety differs from other cultivars known to the inventor, including its parents, in the following traits, which have been repeatedly observed and are determined to be the unique and stable characteristics of ‘Arraone’:

• • 1. Strong variety, producing high crop and large bunches constantly;
  • 2. Berries and bunches are very uniform and attractive;
  • 3. Berry size is large, bright white color; grapes are very firm;
  • 4. Time of ripening is the last week of August and the general harvest time is the beginning of September;
  • 5. Holds very well in cold storage and transportation.

These characteristics in combination distinguish ‘Arraone’ as a new and distinct Grapevine cultivar. All observations were made from four year old specimens grown in Bakersfield, Calif., from April to September 2003.

BRIEF DESCRIPTION OF ILLUSTRATIONS

The accompanying photographic illustrations show typical specimens of vegetative growth of four year old specimens of the new variety, in color as nearly true as it is reasonably possible to make in a color illustration of this character. Colors in the photograph may differ from the color values cited in the detailed botanical description below, which accurately describes the colors of the new Grapevine.

DESCRIPTION OF THE NEW VARIETY

Referring now specifically to the new and distinct variety of Grapevine, the following is a detailed description of ‘Arraone’ with color description where indicated by reference to The Royal Horticultural Society Colour Chart, except where common terms of color definition are employed.

The new variety of Grapevine as herein described may vary in slight detail due to climatic, soil and cultural conditions under which the variety may be grown, the present description being of four year old specimens of the variety as grown from its own root at Bakersfield, Calif., between April and September of 2003.

    • Resistance/susceptibility to disease and pest.—No difference from other Vitis Vinifera varieties.
• Comparison to Thompson seedless: Thompson seedless berry shape and color is the closest commercial common variety to the new variety, ‘Arraone’. The harvest time of Thompson seedless is close as well, the new variety maturity time is about 30 days later than Thompson seedless, the vine size of the new variety is smaller by 20% than Thompson seedless.

The Thompson seedless leaves are different from the new variety by their thickness, the Thompson seedless leaves being much thinner than the new variety. The ‘Arraone’ variety sinus is about 2⅛ inches in depth while the Thompson seedless sinus is about 1½ inches.

• • • Thompson seedless leaf color.—Upper side is Green group near color 137A; Bottom side is Green group near color 137C.

Leaves of the same age are almost equivalent in size. The leaf of the Thompson seedless variety (about 8½ inches) is slightly wider than that of the ‘Arraone’ variety (from about 3 5/16 inch to about 4 3/16 inch).

The canes are smooth and round in both varieties, however the cane color of the Thompson seedless is brighter than that of the new variety.

• • • Cluster and berries shape.—Fruit shape — Thompson Seedless variety have elongate berry with long bunches and low-medium fertility while the new variety berry is round and large. Fruit set — both varieties are self fertile and set high number of berries.

The common characteristics of the two varieties is very small and in fact they are different in most aspects, but unfortunately there is no other white variety of the close period of ripening.
