Abstract

This invention is a new and distinct grapevine variety denominated ‘IFG Thirty-four’. The new grapevine plant is characterized by producing small naturally seedless reddish black to black berries having round shape with a strong concord-like labrusca flavor. Fruits are medium in acidity, with a very soft juicy texture and have excellent eating quality.

Description

Latin name of the genus and species claimed: Vitis interspecific hybrid.
Variety denomination: ‘IFG Thirty-four’.
BACKGROUND OF THE INVENTION
The new and distinct grapevine plant described and claimed herein originated from a hand pollinated cross of A2304 and 01114 bulk (a bulked pollen composed of two unnamed sibling Vitis interspecific hybrid selections from the IFG breeding program) hybridized in May 2004. The abortive seed traces were subsequently embryo cultured and the resulting 124 plants were planted in 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. and were found to reproduce true-to-type through at least one generation of asexual reproduction.
BRIEF SUMMARY OF THE INVENTION
The new grapevine ‘IFG Thirty-four’ is characterized by producing small naturally seedless reddish black to black berries having round shape with a strong concord-like labrusca flavor. Fruits are medium in acidity, with a very soft juicy texture and have excellent eating quality. Berries color readily even in hot climatic conditions and produce completely colored reddish black to black berries. Vines are productive and can be pruned to short spurs. Clusters are medium size, and often do not set enough berries which can be ameliorated by tipping before bloom. Berry size can be increased by applying gibberellic acid. The new grapevine plant differs from its maternal parent A2304 by having reddish black to black berry color with a round shape and small residual seed trace as opposed to the elongated white berries with large seed traces of A2304. ‘IFG Thirty-four’ ripens approximately one month before A2304. ‘IFG Thirty-four’ can be distinguished from either of its pollen parents in 01114 bulk, by having much larger cluster size than either of the 01114 siblings and by having a more black color as opposed to the more red color of the siblings.
‘IFG Thirty-four’ is most similar to the Tomcord (nonpatented) variety. It differs from ‘Tomcord’ by ripening earlier, by having larger berry size, by having smaller residual seed traces, and by having a looser more open cluster density.
‘IFG Thirty-four’ is also somewhat similar to ‘Concord Seedless’ but can be distinguished by having larger, looser clusters with larger berry size and smaller seed traces than ‘Concord Seedless’.
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, and slipskin texture. The new grapevine variety is being introduced because of its excellent concord-like flavor combined with seedlessness, and good adhesion of skin and flesh.
BRIEF DESCRIPTION OF THE DRAWING
The accompanying photographic drawing in FIG. 1 illustrates in full color ‘IFG Thirty-four’, taken from a 4-year-old vine.
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. The left side of the drawing has a mature leaf and a typical berry in cross-section. A mature fruit cluster is represented in the center of the drawing. A young shoot with tendrils can be seen on the right side of the drawing
 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).
