Grapevine ‘Sheegene-22’

Abstract

A new and distinct variety of grapevine characterized by the production of medium, red-colored seeded grapes that mature in early September, approximately two to three weeks later than ‘Red Globe’ (U.S. Plant Pat. No. 4,787) 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-22’.

CROSS REFERENCE TO RELATED APPLICATIONS

The claimed plant is not subject of a related application.

STATEMENT OF ANY FEDERALLY-SPONSORED RESEARCH AND DEVELOPMENT

The claimed plant is not subject of Federally-sponsored research or development.

VARIETY DENOMINATION

The new variety of Vitis vinifera is the result of hybridization of ‘Princess’ (unpatented), the pollen parent, with ‘Red Globe’ (U.S. Plant Pat. No. 4,787), the seed parent, in Spring 2000 at Porterville, Calif. The new variety was first planted in Spring 2001 at Fowler, Calif. The new variety was asexually propagated in Fowler, Calif., in Spring 2010 and grafted on to ‘Freedom’ virus-free, rootstock. Two hundred grapevines of the new variety were planted in a variety lot block of Vitis vinifera located approximately fifteen miles south and west of Fresno, Calif., on the southwest side of Henderson Road. The new variety has been shown to maintain its distinguishing characteristics through asexual propagation.

The new variety is distinguished from its pollen parent, ‘Princess’ (unpatented), in that the new variety produces red-colored seeded grapes, as compared to the white-colored seedless grapes produced by its pollen parent, ‘Princess’ (unpatented). The new variety is distinguished from its seed parent, ‘Red Globe’ (U.S. Plant Pat. No. 4,787), in that the new variety produces medium sized red-colored seeded grapes, as compared to its seed parent, ‘Red Globe’ (U.S. Plant Pat. No. 4,787), that produces exceptionally large red-colored seeded grapes.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct variety of grapevine that produces a medium, red-colored seeded grape that matures during early September when grown in the San Joaquin Valley of Central California.

SUMMARY OF THE INVENTION

The ‘Sheegene-22’ grapevine is characterized by producing a medium, red-colored seeded grape that has good flavor and it is productive and mature for harvesting and shipment in early September when grown in the San Joaquin Valley of Central California. The new variety can be compared to ‘Red Globe’ (U.S. Plant Pat. No. 4,787) but the grapes produced by the new variety mature approximately two to three weeks later and are medium in size, among other distinguishing characteristics.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying drawing is a color photograph that displays, across the top, a terminal shoot with leaves and tendrils; immediately below on the left are two small grape clusters with peduncles. To the right and below the small grape clusters are several tendrils. In the center position is a large grape cluster with peduncle. To the left of the large cluster are three grapes on a modified tendril and below the large cluster is a mature leaf displaying the lower surface view. To the right are two grape berries, the berry on the left is cut in half transverse to the longitudinal axis and the berry on the right is cut longitudinally with both berries displaying flesh tissues. To the far right is a mature grape leaf displaying the upper surface view and along the right margin is a mature cane displaying buds. Along the bottom are two immature leaves with the leaf on the left displaying the upper surface view and the leaf on the right displaying the lower surface view.
