Seedless table grape (grapevine) named ‘ARRATWENTYTHREE’

Abstract

A new distinct variety of grapevine named ARRATWENTYTHREE abundantly forms attractive meaty seedless berries with a dark red violet skin coloration; in dense medium-to-large clusters which display a naturally sweet flavor. 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.

Claims

1. A new and distinct grapevine, botanically known as Vitis vinifera, identified as ARRATWENTYTHREE, substantially as shown and described herein.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) 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.

SHIPPING CHARACTERISTICS

(4) (E.g. number of days fruit has been stored under specific conditions):

(5) Fruit was in cold storage. Stored in poly bags inside Styrofoam boxes with sulfur pads. After 60 Days: rachises were 75% green; 2% berry shuttering; no berry wrinkling or cracks were apparent.

DNA PROFILE

(6) To further the characterize the new variety DNA was extracted from plant samples and a DNA profile was obtained at California Seed & Plant Lab, California USA using base pairs for 10 standard microsatellite DNA markers. The data is presented hereafter.

(8) The ARRATWENTYTHREE variety has not been observed under all possible environmental conditions to date. Accordingly, it is possible that the phenotypic expression may vary somewhat with changes in light intensity and duration, cultural practices, and other environmental conditions.

(9) Additional information relating to plant and fruit disease and pest resistance or susceptibility has not been observed to date. Specification of the plant hardiness zone and the heat/cold resistance has not been observed to date.
