Grapevine plant named ‘95-133’

Abstract

A new and distinct grapevine plant particularly distinguished by having green, large, seedless berries, high vigor, berries with a very uniform skin color and medium productivity, is disclosed.

Description

Genus and species: Vitis vinifera.

Variety denomination: ‘95–133’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct cultivar of grapevine botanically known as Vitis vinifera and hereinafter referred to the cultivar name as grapevine ‘95–133’. The new cultivar originated from a cross conducted in May 1994 in Delano, Calif. between the proprietary grapevine plant ‘90–4981’ (unpatented) and the proprietary male parent ‘C.G. 88–552’ (unpatented). The seeds produced from the cross were subsequently planted in in Delano, Calif. A single plant selection was chosen for further asexual propagation in January 2005 in Delano, Calif.

The new cultivar has been asexually reproduced repeatedly by vegetative cuttings in Delano, Calif. over a three and one-half year period. The present invention has been found to retain its distinctive characteristics through successive asexual propagations.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishing characteristics of this new cultivar when grown under normal horticultural practices in Delano, Calif:.

• • 1. Green, large seedless berries;
  • 2. High vigor with medium productivity; and
  • 3. Berries with a very uniform skin color.

DESCRIPTION OF THE PHOTOGRAPHS

This new grapevine plant is illustrated by the accompanying photographs which show clusters of fruit thereof, leaves, canes, tendrils and berries; the colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photographs are taken from a plant about 3 and one-half years old, grown in a field in Delano, Calif. in July 2008 (at veraison) and in September 2008 (at harvest).

DESCRIPTION OF THE NEW CULTIVAR

The following detailed description sets forth the distinctive characteristics of ‘95–133’. The data which defines these characteristics were collected from asexual reproductions carried out in Delano, Calif. The plant history was taken on 3 and one-half year old grapevines grown under field conditions in Delano, Calif. All color references were obtained under natural light. All major color code designations are by reference to Munsell Color Charts for Plant Tissues by Munsell Color, 617 Little Britain Rd., New Windsor, New York 12553–6148. Common color names are also occasionally employed. For the distribution of the tendrils, please refer to publication “Grape Varieties and Rootstock Varieties” by Pierre Galet, 1998 English Edition, Oenoplurimedia sarl, Chateau de Chaintre, 71570 Chaintre, France (where tendril distribution is intermittent, Os, 1s and 2s are referred to as follows: 0 is a node without a tendril; 2 refers to 2 nodes in a row with a tendril; and 1 is a single node with a tendril).
