Description

Latin name of the genus and species claimed: Vitis vinifera.

Variety denomination: ‘IFG Eleven’.

BACKGROUND OF THE INVENTION

The new and distinct grapevine described and claimed herein originated from a hand pollinated cross of the IFG 02013-090-033, an unnamed seedless selection from the IFG breeding program and the IFG 01034-069-026 another unnamed seedless selection from the IFG breeding program hybridized in May 2005. The abortive seed traces were subsequently embryo cultured and the resulting plant was planted in the field in April 2006. The present variety of grapevine was selected as a single plant in September 2007 and was first asexually propagated by hardwood cuttings in December 2007. The resulting propagules were planted during April 2008 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 Eleven’ is characterized by producing naturally large, narrow elliptic, seedless berries having very small residual seed traces. Berries are firm, crisp in texture and ripen in mid to late season. Fruits normally ripen in early September near Delano, Calif.

To the inventor's knowledge, the known variety which the new grapevine variety is most similar to is the Thompson Seedless variety. ‘IFG Eleven’ can be distinguished from the Thompson Seedless variety by ripening almost one month later. The flesh of the ‘IFG Eleven’ is crisper than the flesh of the Thompson Seedless variety. ‘IFG Eleven’ does not require applications of gibberellin to thin clusters or size berries to obtain commercially acceptable berry size as is required for the Thompson Seedless variety. The ‘IFG Eleven’ has lower acidity than the Thompson Seedless variety. The ‘IFG Eleven’ is much more productive than the Thompson Seedless variety and can be spur pruned while Thompson Seedless requires cane pruning to attain commercially acceptable yields.

BRIEF DESCRIPTION OF THE FIGURE

The accompanying photographic illustration in FIG. 1 illustrates in full color ‘IFG Eleven’. The colors are as nearly true as is reasonably possible in a color representation of this type.

 DETAILED BOTANICAL DESCRIPTION OF THE INVENTION
