USPP24316P3 - Grape vine plant denominated ‘JPD-001’ - Google Patents

Abstract

A new and distinct variety of grapevine denominated ‘JPD-001’, which is characterized by its large natural berry size, increased responsiveness to berry size augmentation, and lack of a noticeable seed trace, is disclosed.

Description

RELATED APPLICATIONS

The present Application claims priority of U.S. Provisional Patent Application No. 61/593,400, entitled “Improved Vitis vinifera Variety,” and filed on Feb. 1, 2012, and which is incorporated herein by reference in its entirety.

STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT

Not Applicable.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct variety of grapevine, Vitis vinifera, which is hereinafter denominated by the variety name ‘JPD-001’. More specifically, the invention relates to a grapevine that produces fruit maturing for commercial harvesting and shipment around August 20, in the San Joaquin Valley of Central Calif. The fruit is naturally large and responsive to berry size augmentation treatments. There is no lignified seed trace, and the berries exhibit excellent crispness and a skin not prone to cracking.

The grapevine of the present invention originated from the white, seedless variety, Sheehan-Genetics 10-418 (unpatented). In the spring of 2002, Sheehan-Genetics 10-418 was grafted onto 2-A Thompson Seedless in a variety plot owned by Jakov P. Dulcich and Sons, near McFarland, Calif. The plant that resulted from this grafting was grown from 2002 until 2006, at which time asexual one-bud cuttings of plants resulting from the Sheehan-Genetics 10-418/2-A Thompson Seedless graft were selected from this vineyard and grafted upon a variety known as Crimson at another Jakov P. Dulcich and Sons varietal plot near Delano, Calif. In January, 2010, select samples from this plot exhibiting characteristics desired for what would become JPD-001 were propagated by one-bud asexual cuttings and grafted onto Red Globe (U.S. Plant Pat. No. 4,787) in a variety plot near McFarland, Calif. Resulting plants harvested in 2011 were stable, unique, and distinguishable from the parent plant material. The stability of the resulting plants was demonstrated again in 2012, with additional production of the new variety. These resulting plants are the subject of this plant patent application.

SUMMARY OF THE INVENTION

A new grape vine, denominated JPD-001, is of Vitis vinifera parentage. JPD-001 is a large berry-size, white, seedless grape maturing for harvest in approximately the third week of August in the San Joaquin Valley of Central Calif. JPD-001 is distinguished from its parent cultivar, Sheehan-Genetics 10-418, in that it has a much larger natural berry size, crisper texture, and lacks a noticeable seed trace. The lack of a noticeable seed trace is due to the fact that the aborted seed does not lignify, and is aborted much earlier in development and maturity as compared to the parent variety. The present variety also exhibits a heightened response to berry size augmentation treatments.

BRIEF DESCRIPTION OF THE ILLUSTRATIONS

The illustrations of the grapevine of the present invention are color photographs showing the following:

FIG. 1 shows the new variety growing on a trellis in the field.

FIG. 2 shows growing tips, leaves, and a berry cluster of the new variety.

FIG. 3 shows a berry cluster of the new variety, as well as cross-sections of the berries thereof. A measurement of berry size is also provided.

DETAILED DESCRIPTION OF THE INVENTION

The following is a detailed description of plants in the new variety, JPD-001, grown outdoors near McFarland, Calif., on their own rootstock. The color-terminology used herein is in accordance with The Royal Horticultural Society Colour Code.

JPD-001 is a large berry-size, white, seedless grape maturing for harvest in approximately the third week of August in the San Joaquin Valley of Central Calif.
