Grape plant named ‘ARRATWENTYNINE’

Abstract

A new distinct variety of grapevine named ‘ARRATWENTYNINE’ abundantly forms attractive large firm and meaty seedless berries with a red skin coloration; in medium-large clusters which display a sweet apple flavor. The fruit commonly is ready for harvesting during 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 ‘ARRATWENTYNINE’.

BACKGROUND OF THE INVENTION

A breeding program was initiated during the late 90's near Bakersfield in San Joaquin Valley of Central California. In 2006, 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 female and introducing pollen from another male origin. The female parent of the new variety was the A.3. which is a medium red very productive grape variety with a large seed trace (non-patented in the United States). The male parent (i.e. the pollen parent) of the new variety was GAW5 which is a large white crisp, seedless grape variety with medium fertility (non-patented in the United States).

Comparison of ‘ARRATWENTYNINE’ with its parents:

				Flame
		A.3.	GAW5	(Comparison
	ARRATWENTYNINE	(Mother)	(Father)	Variety)
Seed trace	None	Large	None	Small to none
Berry	Obtuse ovoid	Ovoid	Ovoid	Globose
shape
Bunches	32-36	48	32-36	28-36
per vine
Fertility	High	Very high	Medium	Medium-good

The parentage of the new variety can be summarized as follows:A.3.×GAW5

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 2007 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 characteristics:

• • (a) Forms attractive large firm and meaty seedless berries with a red skin coloration; in large clusters which display a sweet apple flavor,
  • (b) Commonly bears fruit during the month 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 2009 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 2010, 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.

SUMMARY OF THE INVENTION

The new variety ‘ARRATWENTYNINE’ is a large red seedless table grape with a medium-high production, e.g., about 32-36 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., shows that the forgoing and other distinguishing characteristics come true to form and are established and transmitted through succeeding propagations.

BRIEF DESCRIPTION OF THE DRAWING

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