Abstract

A new and distinct variety of grapevine which is somewhat remotely similar to the ‘Thompson Seedless’ grapevine, but from which it is distinguished in a number of respects by producing fruit with a delayed period of cluster ripening occurring in mid October for harvesting and shipment, or approximately four weeks after the fruit produced by the ‘Thompson Seedless’ grapevine and wherein the fruit is large, having a mild flavor, a light green skin coloration and a firm, crisp flesh.

Description

Latin name of the genus and species of the plant claimed: Vitis vinifera.

BACKGROUND OF THE NEW VARIETY

The present invention relates to a new and distinct variety of grapevine, which will hereinafter be denominated varietally as the ‘Blanc Seedless’ grapevine, and, more particularly, to a grapevine which is large, vigorous and productive, the fruit of which is mature for commercial harvesting and shipment in mid October in the San Joaquin Valley of central California.

The ‘Thompson Seedless’ grapevine, particularly when viewed from a historical vantage point, is one of the most commercially successful grapevines to have been discovered and commercialized. The San Joaquin Valley of central California, one of the most productive areas of the world for grapevine borne crops, has seen plantings of many thousands of acres of this variety over many decades. In some respects, it is the commercial standard by which many other varieties are judged. Nonetheless, there have been many subsequently discovered, commercially successful varieties of grapevines.

With these considerations in mind, it is always a desire in experimentation to discover new grapevine varieties which have improved characteristics relative to prior successful varieties. For example, the objective may be to discover a new variety which has the attractive characteristics of the prior variety, but which may be distinct therefrom in certain respects, such as the ripening date. In this example, the extension of the market for such fruit resulting from the existence of a different ripening date enhances the market value of the fruit produced thereby, in some instances for both varieties.

The grapevine of the present invention has many of the attractive characteristics of prior commercially successful varieties, while possessing distinctive qualities which make it uniquely appealing.

ORIGIN AND ASEXUAL REPRODUCTION OF THE NEW VARIETY

The present variety of grapevine hereof, Vitis vinifera, was discovered by the inventor in a grapevine breeding program initiated in 1992 in a vineyard which is located near Delano, in San Joaquin Valley of central California. The grapevine of the present invention was discovered in a cross breeding of the ‘Red Globe’ grapevine (female) (U.S. Plant Pat. No. 4,787) and the ‘Crimson’ grapevine (male), both commercially successful varieties of grapevines producing red fruit and with complex parentage grown in California. Throughout the season, the newly discovered variety, evidenced that the fruit produced therefrom is seedless, and the grapevine slightly resembles a large ‘Thompson Seedless’ grapevine. However, the fruit produced thereby has a much later ripening date. The present variety has very distinctive quality characteristics, relative to other known varieties and can be distinguished therefrom in a number of other important respects which may be summarized in part as producing a table grape of outstanding size relative to other seedless varieties and with a delayed period of ripening.

In 1998, the present variety was successfully grafted, for asexual reproduction, on mature ‘Thompson Seedless’ grapevine root stock and planted in the aforesaid vineyard. The inventor monitored the asexually reproduced grapevines of the instant variety and confirmed that, in all respects, the asexually reproduced grapevines were identical to the original grapevine of the new variety.

SUMMARY OF THE NEW VARIETY

The grapevine denominated ‘Blanc Seedless’ is characterized by producing large, generally white, or light green, seedless berries which are ripe for commercial harvesting and shipment in approximately mid October in the San Joaquin Valley of central California. The new variety is, perhaps, most closely similar to the ‘Thompson Seedless’ grapevine, but is distinguished therefrom in a number of respects, including the aforementioned ripening date. The fruit is firm, has a mild flavor, good eating quality and an apparent resistance to adverse conditions.

BRIEF DESCRIPTION OF THE DRAWING

The drawing is a color photograph showing representative portions of the grapevine of the subject invention including a cluster of grapes with attached section of the cane or branch, and foliage disposed to show the under surface of the leaf thereof, a second leaf disposed to show the upper surface thereof, and two berries, or grapes, from the cluster, a first berry sectioned along the axis transverse to the longitudinal axis and laid open to expose the flesh and a second berry sectioned and laid open along the longitudinal axis to expose the flesh, together with a scale to indicate the relative sizes of the portions depicted in the photograph.

DETAILED DESCRIPTION

Referring more specifically to the botanical details of this new and distinct variety of grapevine, the following has been observed under the ecological conditions prevailing at the vineyard of origin which is located near Delano, Calif. All major color code designations are by reference to the Dictionary of Color, by Maerz and Paul. Common color names are also occasionally employed.

The variety of the subject invention was selected by the inventor from a progeny of two hundred twenty (220) seedlings planted in 1994 in a field in the Delano area of the San Joaquin Valley of California. The new variety was then asexually reproduced on ‘Thompson Seedless’ grapevine root stock from the original seedling in the spring of 1998 at the same location. The original disclosure of the asexually reproduced grapevine of the new variety was prepared in the spring of 2003.
