Abstract

A new distinct variety of grapevine named ARDTHIRTYEIGHT abundantly forms attractive crunchy seedless elongated berries with a yellow-green skin coloration, medium density and medium sized clusters which display a naturally sweet flavor which 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, having a firmness 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 ‘ARDTHIRTYEIGHT’.
BACKGROUND OF THE INVENTION
This invention relates to a new and distinct variety of Vitis vinifera and is a mutation of the ARRAFIFTEEN variety. A breeding program was initiated during the late 1990's near Bakersfield in the San Joaquin Valley of Central California. In 2010, during this breeding program, a spontaneous mutation of the ARRAFIFTEEN variety was discovered.

ARRAFIFTEEN
The new variety of the present invention was found as a mutation during asexual propagation in 2010 near Bakersfield in the San Joaquin Valley of Central California, U.S.A. by bud grafting on mature Thompson rootstock (non-patented in the United States).
It was found that the new grapevine of the present invention possesses the following combination of characteristics:
    • (a) Forms attractive crunchy seedless elongated berries with a yellow-green skin coloration; in medium density and medium sized clusters which display a naturally sweet flavor,
    • (b) Commonly bears fruit during the month of August 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.
    • (d) Produces 40 bunches per vine, and an average of about 1-2 bunches per shoot, at a total of 48 lbs. fruit per vine.
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 2012 near Bakersfield in the San Joaquin Valley of Central California, U.S.A. by bud grafting on mature Thompson rootstock (non-patented in the United States). Such asexual propagation has been conducted thereafter in successive years to date 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 ARDTHIRTYEIGHT is a white seedless table grape with a high production, e.g., about 40 bunches per vine, and an average of about 1-2 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 six-year-old specimens of the new variety, vegetatively propagated, 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.
