Grapevine plant named ‘Sheegene-3’

Abstract

The new and distinct variety characterized by a very large red seedless grape that ripens in early August three weeks later than the ‘Flame Seedless’ Grape (unpatented) with good favor, juicy and firm skin. The berries are born 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: Vitis vinifera.

Variety denomination: ‘SHEEGENE-3’.

The claimed plant relates to a new and distinct variety of Vitis vinifera to be known as ‘Sheegene-3’. 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 in the late spring of 2000 by Timothy P. Sheehan of Porterville, Calif., producing a medium to large red seedless grape in early August. The new variety was asexually propagated in the dormant season of 2003/2004 by Timothy P. Sheehan, grafted on ‘Harmony’ (unpatented) virus-free grape rootstock on six vines. The new variety was planted in a Vitis vinifera variety block near Fowler, Calif. on the west side of Thompson Road, north of Adams Road. The red-colored grapes produced by the new variety are medium to large in size with very good flavor and have been shown to maintain their distinguishing characteristics throughout asexual propagation.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct variety of grape which will hereafter be denominated as ‘Sheegene-3’ and more particularly as a grapevine that produces a red seedless table grape which matures in early August in the San Joaquin Valley of Central California. The present variety produces a grape that resembles the ‘Flame Seedless’ Grape (unpatented) but differs because it is larger and has a sweeter flavor than the ‘Flame Seedless’ Grape (unpatented) and matures about three weeks later.

SUMMARY OF THE INVENTION

The claimed plant is characterized by producing a medium to large red seedless grape with very good flavor that is mature for harvesting and shipment in early August. The new variety of grape was propagated in the San Joaquin valley of Central California, and it can be compared to the ‘Flame Seedless’ Grape (unpatented) but that it matures three weeks later, among other distinguishing characteristics.

BRIEF DESCRIPTION OF THE DRAWING

The colored photograph has across the top on the left secondary growth cluster; in the middle is a shoot growth with small leaves followed by another secondary growth cluster on the right; in the middle on the left is a mature cluster with a leaf and petiole displaying the upper leaf surface. Right below in the middle are 4 berries cut in half (2 longitudinal and 2 horizontal) displaying the color of the flesh. Across the bottom is a leaf and petiole with the lower side of the leaf displayed; to the right is a small shoot with tendrils; at the bottom is mature cane with leaves and nodes.
