Abstract

This invention is a new and distinct grapevine variety denominated ‘IFG Twenty-three’. The new grapevine is characterized by producing naturally large seedless reddish black berries having a spherical shape with a mild fruity labrusca flavor somewhat similar to the Kyoho variety but smaller in size and seedless.

Description

Latin name of the genus and species claimed: Vitis interspecific hybrid.
Variety denomination: ‘IFG Twenty-three’.
BACKGROUND OF THE INVENTION
The new and distinct grapevine described and claimed herein originated from a hand pollinated cross of the 01032-067-202, an unnamed seedling selection from the IFG breeding program, and the Arkansas 2798 (non-patented, non-released interspecific selection) 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 October 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-three’ is characterized by producing naturally large seedless reddish black berries having a spherical shape with a mild fruity labrusca flavor somewhat similar to the Kyoho variety but smaller in size and seedless. Fruits normally ripen mid to late season about early to mid-September near Delano Calif. Fruits are fairly low in acidity, with medium dense firm texture, having occasionally noticeable seed traces and may be difficult to color in hot climatic conditions. Berries may occasionally split at the stylar end. Attachment of the berry to the pedicel is strong. Vines are productive and can be pruned to short spurs. The new grapevine differs from its maternal parent the 01032-067-202 by having dark red rather than light green berries and by having a medium strong fruity labrusca type flavor as opposed to the neutral flavor of the 01032-067-202. ‘IFG Twenty-three’ can be distinguished from its pollen parent, Arkansas 2798, by its dark reddish black color as opposed to full black color, by having round berries as opposed to obovoid berries and by having a mild labrusca flavor rather than a strong labrusca flavor of the Arkansas 2798.
The interspecific nature of the vine is very evident. Vines are very vigorous with a more horizontal growth habit and large leaves as compared to typical varieties of the Vitis vinifera species.
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 ‘IFG Twenty-three’ is being introduced because of its unique combination of labrusca flavor combined with firm texture, seedlessness, good adhesion of skin and flesh and naturally large berry size and its resemblance to the Kyoho grape.
BRIEF DESCRIPTION OF THE DRAWING
The accompanying photographic drawing in FIG. 1 illustrates in full color ‘IFG Twenty-three’. 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. Mature leaves can be seen on the left side of the drawing. A mature fruit cluster is represented in the center of the drawing. A young shoot tip with tendrils and young leaves can be seen on the right side of the drawing along with a typical berry and a berry in cross-section.
 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 in 2001 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).
