Abstract

This invention is a new and distinct grapevine variety denominated ‘IFG Thirty’. The new grapevine ‘IFG Thirty’ is characterized by producing naturally large, ovate to elongated ovate, black seedless berries which are firm in texture, medium low in acidity and ripen late in the growing season.

Description

Latin name of the genus and species claimed: Vitis interspecific hybrid.
Variety denomination: ‘IFG Thirty’.
BACKGROUND OF THE INVENTION
The new and distinct grapevine described and claimed herein originated from a hand pollination of the 06095-096-043, an unnamed interspecific seedling selection from the IFG breeding program, and ‘IFG Sixteen’ (U.S. Plant Pat. No. 25,434) hybridized in May 2009. The abortive seed traces were subsequently embryo cultured and the resulting 47 plants were planted in the field in April 2010. The present variety of grapevine was selected as a single plant in September 2012 and was first asexually propagated by hardwood cuttings in December 2012 near Delano, Kern County, Calif. These resulting cuttings produced second generation plants that were planted during April 2013 at the International Fruit Genetics LLC research facility near Delano, Kern County, Calif. and were observed for four years and found to be true-to-type.
BRIEF SUMMARY OF THE INVENTION
The new grapevine ‘IFG Thirty’ is characterized by producing naturally large, ovate to elongated ovate, black seedless berries which are firm in texture, medium low in acidity and ripen late in the growing season. Fruits normally ripen late August to mid-September near Delano, Calif.
To the inventor's knowledge, the new grapevine variety is most similar to the ‘Autumn Royal’ variety. ‘IFG Thirty’ can be distinguished from the Autumn Royal variety by having a broader, more desirable cluster shape and thicker and tougher peduncle and pedicle, by having a much smaller residual seed trace, by having no tendency to develop an astringent flavor and by having higher, more consistent yields.
‘IFG Thirty’ can be distinguished from its female parent, the IFG 06095-096-043, by having larger, more elongated berries which are more fully black in color and by having larger clusters. ‘IFG Thirty’ can be distinguished from its pollen parent, the ‘IFG Sixteen’, by having firmer berries that more easily attain full black color under hot conditions and by ripening slightly earlier.
BRIEF DESCRIPTION OF THE DRAWING
The accompanying photographic drawing in FIG. 1 illustrates in full color ‘IFG Thirty’, 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 top portion of the drawing has a mature leaf. A mature fruit cluster is represented in the center of the drawing along with a typical berry in cross section. A young shoot tip with tendrils and young leaves can be seen on the bottom portion 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).
