Abstract

This invention is a new and distinct grapevine variety denominated ‘IFG Forty-seven’. The new grapevine ‘IFG Forty-seven’ is characterized by producing small dark red berries having a broad ellipsoid shape with a unique strong fruity labrusca flavor reminiscent of artificial grape flavor. Fruits normally ripen in early season about late June to early July near Delano Calif. Fruits have medium to firm texture. Vines are productive and can be pruned to short spurs.

Description

Latin name of the genus and species claimed: Vitis interspecific hybrid.
Variety denomination: ‘IFG Forty-seven’.
BACKGROUND OF THE INVENTION
The new and distinct grapevine described and claimed herein originated from a hand pollinated cross of IFG 05027-071-124, and IFG 05006-068-194, both unnamed interspecific selections from the IFG breeding program hybridized in May 2010. The abortive seed traces were subsequently embryo cultured and the resulting population of 17 plants was planted in the field in April 2011. The present variety of grapevine was selected as a single plant in June 2012 and was first asexually propagated by hardwood cuttings in December 2012 near Delano, Kern County, Calif. The resulting propagules were planted during April 2013 near Delano, Kern County, Calif. and were observed for five years and found to reproduce true-to-type through at least two generations of asexual reproduction.
BRIEF SUMMARY OF THE INVENTION
The new grapevine ‘IFG Forty-seven’ is characterized by producing small dark red berries having a broad ellipsoid shape with a unique strong fruity labrusca flavor reminiscent of artificial grape flavor. Fruits normally ripen in early season about late June to early July near Delano Calif. Fruits have medium firm texture. Vines are productive and can be pruned to short spurs. The new grapevine differs from its female parent the IFG 05027-071-124 by having a more broad ellipsoid rather than round berry shape; by having a larger, more dense cluster and by having a less notable muscat flavor and a stronger labrusca type flavor. ‘IFG Forty-seven’ can be distinguished from its pollen parent, IFG 05006-068-194, by having a darker red berry color, by having a larger cluster and by ripening approximately two weeks earlier. ‘IFG Forty-seven’ is most similar to ‘IFG Thirty-one’ (U.S. Plant Pat. No. 29,936 P2). It differs from ‘IFG Thirty-one’ by ripening approximately three weeks earlier, by having a brighter red berry color, and by exhibiting a lower propensity for tip cracking during ripening. ‘IFG Forty-seven’ is somewhat similar to ‘Flame Seedless’ (not patented), but differs by ripening earlier, by having a slightly softer berry texture, by developing a darker red berry color and by having a strong labrusca type flavor as opposed to the neutral flavor of ‘Flame Seedless’. The new grapevine variety, ‘IFG Forty-seven’, is being introduced because of its unique labrusca flavor combined with seedlessness, good adhesion of skin to flesh and its earliness of ripening.
BRIEF DESCRIPTION OF THE DRAWING
The accompanying photographic drawing illustrates in full color a 5-year-old plant of ‘IFG Forty-seven’. 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 fruit depicted in the drawing is in its natural state and has not been treated with gibberellic acid. The drawing is of a mature leaf, a mature fruit cluster, a typical berry in cross section and a young shoot tip.
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 2016 by The Royal Horticultural Society, London, England.
Throughout this specification, subjective description values conform to those set forth by the UPOV International Union for the Protection of New Varieties of Plants publication ‘Grapevine Vitis L. Guidelines’.
