Abstract

A new distinct variety of grapevine named ‘ARRATHIRTYFOUR’ abundantly forms attractive meaty and crunchy seedless berries with a green skin coloration; in medium-to-large clusters which display a sweet and natural flavor. The fruit commonly is ready for harvesting during July 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 a varietal denomination ‘ARRATHIRTYFOUR’.
BACKGROUND OF THE INVENTION
A breeding program was initiated during the late 90's near Bakersfield in San Joaquin Valley of Central California. In 2011, 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 E.Z., a white fertile variety without a seed trace (non-patented in the United States).
The male parent (i.e. the pollen parent) of the new variety was GAW 15 which is a mid-season white grape variety with thin skin and a natural acid flavor (non-patented in the United States).

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 2012 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 meaty and crunchy seedless berries with a white skin coloration; in medium-to-large clusters which display a sweet and natural flavor,
    • (b) Commonly bears fruit during the month of July 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 2013 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 2014 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 ‘ARRATHIRTYFOUR’ is a large, white seedless table grape with a high production, e.g., about 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., 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.
FIG. 1 shows leaves, stems and grapes of ‘ARRATHIRTYFOUR’.
