Grapevine ‘Sheegene-10’

Abstract

A new and distinct variety characterized by medium to large, red-colored seedless grapes with a very good flavor that ripen in late July, approximately two weeks later than the flame seedless grape (unpatented), when grown in the San Joaquin Valley of Central California. The grapes of this new variety are produced on strong woody branches and stems and are well adapted to commercial handling.

Description

Latin name of the genus and species of the plant claimed: The claimed plant relates to a new and distinct variety of Vitis vinifera to be known as ‘Sheegene-10’.

Variety denomination: This invention relates to a new discovery and asexual reproduction of a new variety of Vitis vinifera. The new variety was first hybridized by Timothy P. Sheehan of Porterville, Calif., in late Spring 2000. The pollen parent is ‘Princess’ (unpatented) and the seed parent is ‘Red Globe’ (U.S. Plant Pat. No. 4,787). The new variety was asexually propagated in the dormant season of 2003, grafted on ‘Harmony’, virus-free rootstock near Fowler, Calif. Five vines were 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 red-colored seedless grapes produced by the new variety are medium to large in size and mature approximately two weeks later than ‘Flame Seedless’ (unpatented). The new variety has been shown to maintain its distinguishing characteristics through asexual propagation.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct variety of grape which will hereinafter be denominated as ‘Sheegene-10’ and more particularly as a grapevine which produces a medium to large, red-colored seedless grape that matures in late July in the San Joaquin Valley of Central California. The new invention resembles ‘Flame Seedless’ (unpatented) but it produces a larger grape with a very sweet flavor, and matures approximately two weeks later.

SUMMARY OF THE INVENTION

The ‘Sheegene-10’ is characterized by producing a medium to large, red-colored seedless grape with very good flavor that is mature for harvesting and shipment in late July in the San Joaquin Valley of Central California. The new variety of grape can be compared to ‘Flame Seedless’ (unpatented) but the grapes are larger and mature about two weeks later, among other distinguishing characteristics.

Across the top of the color photograph on the left is a small shoot with leaves and tendrils, a secondary growth small cluster and berries; in the center is a grape leaf and petiole; and to the right is a display of the topside of a leaf. Across the middle of the color photograph on the left is a major grape cluster; in the center is a secondary growth cluster; and to the right are small shoot leaves and tendrils. Across the bottom of the color photograph on the left are four grapes cut in half longitudinally as well as horizontally displaying the flesh and shape; just above is a leaf and petiole displaying the bottom surface of the leaf; and to the right is a section of mature cane with leaves and nodes.
