Abstract

This invention is a new and distinct grapevine variety denominated ‘IFG Six’. The new grapevine is characterized by producing naturally large, extremely elongated, narrow diameter, crisp, seedless black berries having a distinct dimple on the distal end. The fruit ripen and are commercially harvestable from late August to mid-September. Berries color to full black and store well.

Description

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

Variety denomination: ‘IFG Six’.

BACKGROUND OF THE INVENTION

The new and distinct grapevine described and claimed herein originated from a hand pollination of the Beita Mouni (non-patented) variety and an unnamed USDA selection designated ‘C22-121’ performed in May 2004. The resulting plants were planted into the field in April 2005. The present variety of grapevine was selected as a single plant in July 2006 and was first asexually propagated by hardwood cuttings in December 2006, near Delano, Kern County, Calif. The resulting propagules were planted during April 2007 near Delano, Kern County Calif.

BRIEF SUMMARY OF THE INVENTION

The new grapevine ‘IFG Six’ is characterized by producing large, extremely elongated cylindrical seedless black fruit with a characteristic dimpled tip. The shape, which to the author's knowledge is unique among seedless table grape varieties, provides consumers with a distinct visual signal to identify the new variety. The new variety is further characterized by producing large berries that do not require any gibberellic acid application or trunk girdling to attain commercially acceptable berry size. Berries are completely black, crisp in texture and of high eating quality. Vines of ‘IFG Six’ are moderately productive. The fruit ripen in mid to late August and are moderately prone to sunburn damage. Fruit store well and are suitable for international commerce and long-term cold storage.

‘IFG Six’ differs from its maternal parent by producing elongated black seedless berries as opposed to seeded white fruits of the ‘Beita Mouni’. It differs from its pollen parent by producing much larger more crisp seedless berries with a distinct dimpled end which the ‘C22-121’ lacks.

BRIEF DESCRIPTION OF THE FIGURE

The accompanying photographic illustration in FIG. 1 illustrates in full color ‘IFG Six’. The colors are as nearly true as is reasonably possible in a color representation of this type.

DETAILED BOTANICAL DESCRIPTION OF THE INVENTION

Throughout this specification, color names beginning with a small letter signify that the name of that color, as used in common speech, is aptly descriptive. Color names beginning with a capital letter designate values based upon R.H.S. Colour Chart, published by The Royal Horticultural Society, London, England.

Throughout this specification subjective description values conform to those set forth by the International Plant Genetic Resources Institute publication ‘Descriptors for Grape’ (Vitis spp.) (1983) which was developed in collaboration with the Office International de la Vigne et du Vin (OIV) and the International Union for the Protection of New Varieties of Plants (UPOV).
