A new distinct variety of grapevine named ‘ARRATWO’ abundantly forms attractive large seedless berries having deep purple/red skin coloration in large clusters. The fruit displays a natural flavor and is meaty in texture. The fruit commonly is ready for harvesting during August in San Joaquin Valley of Central California, U.S.A., and displays good eating qualities as a table grape. The fruit firmness renders the fruit well amenable for handling, shipping, and storage.

1. A new and distinct variety of grapevine, botanically known as Vitis vinifera, identified as ‘ARRATWO’, substantially as shown and described herein.

Classification: The present invention relates to a new Vitis vinifera Grapevine.

Variety denomination: The new Grapevine has the varietal denomination ‘ARRATWO’.

A breeding program was initiated during the late 90's near Bakersfield in the San Joaquin Valley of Central California. In 2001. during this breeding program, a new variety of Vitis vinifera was created by deliberate cross breeding of two parent plants by emasculation of the pollen bearing organ of the male and introducing pollen from another male origin. The female parent of the new variety was the GAW1 which is a large creamy white very productive seedless grape variety (non-patented in the United States). The male parent (i.e. the pollen parent) of the new variety was GZW5 which is a large red meaty and juicy, seedless grape variety with medium fertility (non-patented in the United States).

ARRATWO GZW5
Berry color Red Grayish red
Berry shape Globose Obovate
Seed trace None Seeded
Density of bunch Very dense Loose

The parentage of the new variety can be summarized as follows:

GAW1×GZW5

An artificial pollination was created, and the result was an embryo which possessed unique genetic qualities. The rudiments resulting from the above pollination were embryo rescued.

In 2002 the plant was transplanted to Bakersfield in San Joaquin Valley of Central California.

It was found that the new grapevine of the present invention possesses the following combination of the characteristics:

The new variety during observation to date has displayed no visible disease, and has displayed an ability to well resist cold, drought, heat; but sensitive to direct exposure to sun and wind. The fruit of the new variety has been found to display excellent handling and shipping qualities combined with desirable dessert eating qualities.

The new variety of the present invention has been found to undergo asexual propagation beginning in 2005 near Bakersfield in the San Joaquin Valley of Central California, U.S.A. by grafting on mature Thompson rootstock (non-patented in the United States). Such asexual propagation has been conducted thereafter in successive years through 2008, and has shown that the characteristics of the new variety are strictly transmissible from one generation to another. Accordingly, the new variety undergoes asexual propagation in a true to type manner. The age of the plant shown in the drawing is five years old and the variety was created in 2001.

The new variety ‘ARRATWO’ is a large, deep purple/red seedless table grape with medium to large production, e.g., about 36 to 42 bunches per vine, and an average of about one to two bunches per shoot.

Asexual reproduction by micro propagation of the new variety as performed near Bakersfield, Calif., U.S.A., at Arvin, Calif. Ranch 33 which shows that the forgoing and other distinguishing characteristics come true to form and are established and transmitted through succeeding propagations.

The accompanying photographic illustration shows typical specimens of vegetative growth of five 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.

FIG. 1 shows leaves, stems and grapes of ‘ARRATWO’.

The chart used in the identification of colors is the R.H.S. Colour Chart of The Royal Horticultural Society. The description is based on the observation of plants growing on ‘Thompson Seedless’ rootstock outdoors near San Joaquin Valley of Central California, U.S.A.

To further the characterize the new Arra variety DNA was extracted from dried leaf samples and DNA profiles were obtained in Spain, using base pairs for 14 standard microsatellite DNA markers. The data is presented hereafter.
