Description

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

Variety denomination: ‘IFG Nine’.

BACKGROUND OF THE INVENTION

The new and distinct grapevine described and claimed herein originated from a hand pollinated cross of the Redglobe variety (U.S. Plant Pat. No. 4,787 expired) and the Princess variety (non-patented) hybridized in May 2001. The seeds were subsequently germinated and the resulting plants were planted in the field in April 2002. The present variety of grapevine was selected as a single plant in August 2003 and was first asexually propagated by hardwood cuttings in December 2003 near Delano, Kern County, Calif. The resulting propagules were planted during April 2004 near Delano, Kern County, Calif. and were found to reproduce true-to-type through at least three generations of asexual reproduction.

BRIEF SUMMARY OF THE INVENTION

The new grapevine ‘IFG Nine’ is characterized by producing naturally large, narrow ellipsoid to somewhat cylindrical, red seedless berries which ripen with or slightly before the Crimson variety. Berries have crisp texture, excellent eating quality and are able to develop bright red skin color more readily than the Crimson variety.

To the inventor's knowledge, the known varieties to which the new grapevine variety is most similar are the Crimson Variety (unpatented) and the Sheegene-1 (U.S. Plant Pat. No. 18,937). The ‘IFG Nine’ can be distinguished from the Crimson variety by having much larger natural berry size. The ‘IFG Nine’ does not require the use of gibberellic acid to attain acceptable commercial berry size while the Crimson variety requires gibberellic acid applications and/or girdling to attain acceptable size. ‘IFG Nine’ also colors more easily than the Crimson variety and does not require the application of ethrel or other color enhancing chemicals to attain commercially acceptable red color. The ‘IFG Nine’ can be distinguished from the Sheegene-1 variety by having a slightly more narrow ellipsoid to cylindrical shaped berry as opposed to the more ovate to obtuse ovate berry shape of Sheegene-1. The ‘IFG Nine’ has a larger and less compact cluster than the Sheegene-1. The ‘IFG Nine’ cluster weight is about 1592 grams and has about 255 berries per bunch as opposed to 719 grams with 155 berries per bunch for the Sheegene-1. The berry weight of ‘IFG Nine’ is somewhat smaller than Sheegene-1 being 6.9 to 8.4 grams per berry as opposed to about 11.4 grams for Sheegene-1.

‘IFG nine’ can be distinguished from its parent, the Redglobe variety by producing seedless rather than seeded berries having a smaller more narrow ellipsoid to cylindrical shape as opposed to the round shape of Redglobe. ‘IFG Nine’ can be distinguished from its parent the Princess variety by having red rather than white skin coloration and by its later ripening period. ‘IFG Nine’ can further be distinguished based on the characteristics described below.
