Description

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

Variety denomination: ‘IFG Five’.

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 Summer Royal variety (non-patented) performed in May of 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 of 2003 and was first asexually propagated by hardwood cuttings in December of 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 two generations of asexual reproduction.

BRIEF SUMMARY OF THE INVENTION

The new grapevine ‘IFG Five’ is characterized by producing extremely large, elongated oval seeded purplish to black berries borne on large clusters. The vine is very productive with short spur pruning and the fruit ripen 7 to 10 days before its maternal parent variety Redglobe. Berries have firm texture and excellent eating quality. It attains full black color with difficulty and may exhibit green or red coloration around the pedicle under some conditions. Application of the growth regulator ethrel allows full coloration.

The new grape vine differs from its parent the Redglobe variety by ripening 7 to 10 days earlier and by having larger more elongated berries which are black in color as opposed to the rounder red berries of Redglobe. It differs from its pollen parent by producing much larger seeded berries as opposed to the smaller seedless berries of the Summer Royal variety. To the inventor's knowledge, the known variety to which the new grapevine variety is most similar is the ‘Black Globe’ (U.S. Plant Pat. No. 17,875 P3). ‘IFG Five’ can be distinguished from Black Globe by ripening earlier (mid to late August as opposed to early to mid September for Black Globe), by having a more elongated ovate shape as opposed to the obovoid shape of ‘Black Globe’. ‘IFG Five’ is more productive than the ‘Black Globe’ variety and can be spur pruned and still be highly productive while the ‘Black Globe’ is only medium productive and requires more costly cane pruning to maximize bunch counts. Mature clusters of ‘IFG Five’ are somewhat larger than ‘Black Globe’ and the peduncle is longer.

BRIEF DESCRIPTION OF THE FIGURE

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

 DETAILED BOTANICAL DESCRIPTION OF THE INVENTION
