Abstract

This invention is a new and distinct grapevine variety denominated ‘IFG Twenty-one’. The new grapevine is characterized by producing small naturally seedless red berries having an elliptic shape with a unique combination of muscat and labrusca flavor. The strong fruity flavor is reminiscent of strawberries. Fruits normally ripen very early season about early to mid-July near Delano Calif. Fruits are fairly low in acidity, with medium dense, firm texture. Berries color readily even in hot climatic conditions and produce completely colored bright red berries.

Description

Latin name of the genus and species claimed: Vitis interspecific hybrid.
Variety denomination: ‘IFG TWENTY-ONE’.
BACKGROUND OF THE INVENTION
The new and distinct grapevine described and claimed herein originated from a hand pollinated cross of the 03003-074-251 (unnamed interspecific selection from the IFG breeding program) and the 02089-081-217 (unnamed selection from the IFG breeding program) hybridized in May 2006. The abortive seed traces were subsequently embryo cultured and the resulting population of plants was planted in the field in April 2007. The present variety of grapevine was selected as a single plant in July 2008 and was first asexually propagated by hardwood cuttings in December 2008 near Delano, Kern County, Calif. The resulting propagules were planted during April 2009 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 Twenty-one’ is characterized by producing small naturally seedless red berries having an elliptic shape with a unique combination of muscat and labrusca flavor. The strong fruity flavor is reminiscent of strawberries. Fruits normally ripen very early season about early to mid-July near Delano Calif. Fruits are fairly low in acidity, with medium dense, firm texture. Berries color readily even in hot climatic conditions and produce completely colored bright red berries. Vines are very productive and can be pruned to short spurs. Clusters are large, slightly tight, and require tipping, thinning and sizing with gibberellic acid to enlarge berry size. The new grapevine differs from its maternal parent the 03003-074-251 selection by having red rather than light green berries and by having an elliptic berry shape as opposed to an ovate shape of the 03003-074-251. ‘IFG Twenty-one’ has smaller seed traces and a broader more conical cluster than its maternal parent. ‘IFG Twenty-one’ can be distinguished from its pollen parent, 02089-081-217, by a light red color as opposed to dark red to black color, by having medium firm, slightly less dense flesh, by having a slightly larger seed trace, and by having a combination of muscat and labrusca flavor rather than a neutral vinifera flavor of the 02089-081-217.
Grape breeders have used several native American grape species to improve hardiness, disease and insect resistance as well as incorporate aromatic flavors into the vinifera species. Previously introduced interspecific varieties have had very limited commercial success due to small fruit size, large seed traces, slipskin texture or lack of firmness. The new grapevine variety is being introduced because of its unique combination of muscat and labrusca flavor combined with firm texture, seedlessness, good adhesion of skin and flesh and excellent coloring characteristics.
BRIEF DESCRIPTION OF THE FIGURE
The accompanying photographic illustration in FIG. 1 illustrates in full color ‘IFG Twenty-one’.
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).
