Abstract

A new distinct variety of grapevine named ‘ARRATHIRTEEN’ abundantly forms attractive large seedless berries having a fire red skin coloration in medium-to-large clusters. The fruit displays a sweet crisp flavor and is firm in texture. The fruit commonly is ready for harvesting during the end of June 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.

Description

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

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

BACKGROUND OF THE INVENTION

A breeding program was initiated during the late 90's near Bakersfield in 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 GAR4 which is an oval shaped, dark red grape variety bearing a large seed rudiment (non-patented in the United States). The male parent (i.e. the pollen parent) of the new variety was GZR1 which is a round, pinkish grape variety (non-patented in the United States).

Comparison between ARRATHIRTEEN and FLAME


	ARRATHIRTEEN	FLAME

Vigor	Weak	Vigorous
Berry color	Red	Grayish red
Berry shape	Obovoid	Globose
Seed trace	Rudimentary	None
Flavor	None	Naturally sweet

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

GAR4×GZR1

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 then 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 characteristics:

- (a) Forms attractive large seedless berries having fire red skin coloration in medium-to-large clusters which display a natural and a high sugar content,
- (b) Commonly bears fruit during the end of June in the San Joaquin Valley of Central California, U.S.A., and
- (c) Bears fruit that is firm and is well amenable for storage, handling, and shipping.

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 Seedless’ 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 in the drawing is five years old and the variety was created in 1989.

SUMMARY OF INVENTION

The new variety ARRATHIRTEEN is a large, fire red seedless table grape with large production, e.g., about 40 to 50 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.

BRIEF DESCRIPTION OF THE DRAWINGS

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 ‘ARRATHIRTEEN’.
