Grapevine (Sheegene-11)

Abstract

A new and distinct variety of grapevine characterized by the production of large, green-colored seedless grapes that have a muscat flavor and mature in mid to late July, approximately two to three weeks earlier than thompson Seedless (unpatented) when grown in the San Joaquin Valley of Central California. The grapes of this new variety are produced on strong woody stems and branches and are well adapted to commercial handling.

Description

Latin name of the genius and species of the plant claimed:

The claimed plant relates to a new and distinct variety of Vitis vinifera to be known as Sheegene-11.

Variety denomination:

This invention relates to a discovery and asexual reproduction of a new variety of Vitis vinifera. The new variety of Vitis vinifera is the result of hybridization of Princess (unpatented), the pollen parent, and Red Globe (U.S. Plant Pat. No. 4,787), the seed parent. The new variety was first hybridized by Timothy P. Sheehan of Porterville, Calif. in the late Spring 2000. The new variety was asexually propagated in the dormant season of 2003, bud-grafted on Harmony, virus-free rootstock on one vine. The new variety was planted at that time in a Vitis vinifera variety block located near Fowler, Calif. on the west side of Thompson Road, north of Adams Road. The new variety produces large, green-colored seedless grapes with a Muscat flavor that mature approximately two to three weeks earlier than Thompson Seedless (unpatented).

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct variety of grapevine that produces large, green-colored seedless grapes that mature in mid to late July when grown in the San Joaquin Valley of Central California. The new invention resembles Thompson Seedless (unpatented) but the large, green-colored seedless grapes produced by the new variety have a muscat flavor and mature about two to three weeks earlier.

SUMMARY OF THE INVENTION

The Sheegene-11 grapevine is characterized by producing a large, green-colored seedless grape with a muscat flavor that mature for harvesting and shipment in mid to late July when grown in the San Joaquin Valley of Central California. The new variety can be compared to Thompson Seedless (unpatented) but matures approximately two to three weeks earlier, among other distinguishing characteristics.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying drawing is a colored photograph of the grapes produced by the new variety; several leaves are displayed as well as a typical section of the vine. The top left of the color photograph displays a secondary growth grape cluster; below is a primary growth grape cluster; and to the right of the primary growth grape cluster is another secondary growth grape cluster. The bottom left of the color photograph is a mature leaf with the stem pointing up and left; the leaf is upside down displaying the bottom surface and petiole. The bottom right of the color photograph displays two new shoot growth tips and tendrils, small leaves with reddish pigment. Above the growth tips are four grapes cut in half longitudinally as well as horizontally displaying the flesh and shape of the fruit. To the right of the grapes that are cut in half is a mature cane displaying nodes, small leaves and one mature leaf which displays the topside with petioles.
