Abstract

This invention is a new and distinct grapevine variety denominated ‘IFG Twelve’. The new grapevine is characterized by producing very pointed narrow reddish purple grapes having small to medium sized seed traces.

Description

Latin name of the genus and species claimed: Vitis interspecific hybrid.
Variety denomination: ‘IFG Twelve’.
BACKGROUND OF THE INVENTION
The new and distinct grapevine described and claimed herein originated from a hand pollinated cross of the Calinda variety and A2409 an unnamed interspecific very elongate pointed seedless grape selection from the University of Arkansas breeding program hybridized in May 2002. The abortive seed traces were subsequently embryo cultured and the resulting plant was planted in the field in April 2003. The present variety of grapevine was selected as a single plant in July 2004 and was first asexually propagated by hardwood cuttings in December 2004, near Delano, Kern County, Calif. The resulting propagules were planted during April 2005 near Delano, Kern County, Calif. and were found to reproduce true-to-type through at least two generations of asexual reproduction.
BRIEF SUMMARY OF THE INVENTION
The new grapevine ‘IFG Twelve’ is characterized by producing extremely narrow elongated seedless fruit with a characteristic pointed tip. The shape, which to the author's knowledge is unique among commercially available seedless table grape varieties, provides consumers with a distinct visual signal to identify the new variety. The new variety is further characterized by producing medium firm reddish black fruits which ripen early in the growing season. Berries are moderately crisp in texture, mild flavored and may have small to medium size rudimentary seed traces. Bunches are long with narrow shoulders and are naturally loose so require no gibberellin for berry thinning. Vines of ‘IFG Twelve’ are moderately productive and may require cane pruning. The fruit ripen early season usually mid to late July in Delano.
‘IFG Twelve’ differs from its maternal parent by producing very elongated narrow pointed reddish black berries having small to medium seed traces as opposed to the red elongated fruits having very large seed traces of the Calinda variety. It differs from its pollen parent by possessing more firm berries with reddish black coloration as opposed to the narrow, elongate pointed black fruits of A2409. The skin of ‘IFG Twelve’ is thinner and the taste is less herbaceous than the A2409.
BRIEF DESCRIPTION OF THE FIGURE
The accompanying photographic illustration in FIG. 1 illustrates in full color ‘IFG Twelve’. The photograph was taken outdoors with indirect lighting. 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).
