Abstract

A new and distinct variety of grapevine plant named ‘CAR98-710’ particularly distinguished by black colored, seedless berries, medium to large berries and clusters, and excellent integrity of clusters and berries through October, is disclosed.

Description

Genus and species: Vitis vinifera.

Variety denomination: ‘CAR98-710’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct variety of grapevine botanically known as Vitis vinifera and hereinafter referred to by the variety name ‘CAR98-710’. The new variety originated from a cross conducted in May 1998 in Delano, Calif. between the female grapevine plant named ‘Black Globe’ (U.S. Plant Pat. No. 17,875) and the male grapevine plant named ‘552’ (U.S. Plant Pat. No. 9,916). A single plant was selected for further evaluation and asexual propagation.

The new variety was first propagated in December 2005 in Delano, Calif. by vegetative cuttings and has been asexually reproduced repeatedly by vegetative cuttings for 3 generations. ‘CAR98-710’ has been found to retain its distinctive characteristics through successive asexual propagations.

Plant Breeder's Rights for this variety have not been applied for. ‘CAR98-710’ has not been made publicly available anywhere in the world more than one year prior to filing of this application.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishing characteristics of this new variety when grown under normal horticultural practices in Delano, Calif.

- 1. Black colored, seedless berries;
- 2. Medium to large berries and clusters; and
- 3. Excellent integrity of clusters and berries through October.

DESCRIPTION OF THE PHOTOGRAPHS

This new grapevine plant is illustrated by the accompanying photographs which show clusters of fruit, leaves, canes, tendrils and berries. The colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photographs are taken from a mature plant about 7 years old, grown in a field in Delano, Calif.

FIG. 2 shows a close up of a growing shoot tip at bloom.

FIG. 3 shows the upper surface of a mature leaf.

FIG. 4 shows the lower surface of a mature leaf.

FIG. 5 shows a close up of an immature primary fruit cluster.

FIG. 6 shows mature fruit clusters on the vine.

DESCRIPTION OF THE NEW VARIETY

The following detailed descriptions set forth the distinctive characteristics of ‘CAR98-710’. The data which defines these characteristics were collected from asexual reproductions carried out in Delano, Calif. The plant history was taken on mature 7 year old grapevines grown under field conditions in Delano, Calif. All color references were obtained under natural light. Color references are primarily to the Munsell Color Charts for Plant Tissues by Munsell Color, 617 Little Britain Rd., New Windsor, N.Y. 12553-6148. Common color names are also occasionally employed.

COMPARISON WITH PARENTAL AND COMMERCIAL VARIETIES

‘CAR98-710’ differs from the female parent grapevine plant named ‘Black Globe’ (U.S. Plant Pat. No. 17,875) in that ‘CAR98-710’ has seedless, globose shaped berries, whereas ‘Black Globe’ has seeded, obovate shaped berries.

‘CAR98-710’ differs from the male parent grapevine plant named ‘552’ (U.S. Plant Pat. No. 9,916) in that ‘CAR98-710’ has black, globose shaped berries, whereas ‘552’ has red, obovoid shaped berries.

‘CAR98-710’ differs from the commercial grapevine plant named ‘Autumn Royal’ (unpatented) in that ‘CAR98-710’ has medium to large fruit clusters and globose shaped berries maturing in September, whereas ‘Autumn Royal’ has large fruit clusters and ellipsoidal elongated berries maturing in October. Additionally, the fruit clusters of ‘Autumn Royal’ are generally more loosely filled, have less uniformity, and are longer than ‘CAR98-710’.

‘CAR98-710’ differs from the commercial grapevine plant named ‘Summer Royal’ (unpatented) in that ‘CAR98-710’ is 4 to 5 weeks later maturing with larger berries weighing 9.0 grams, whereas ‘Summer Royal’ is early to mid season maturing with smaller berries weighing 5.0 grams. Additionally, ‘CAR98-710’ has berry clusters that maintain integrity into October, whereas ‘Summer Royal’ has berry clusters that shrivel (dry on the vine) beginning in late August.
