Claims
What is claimed:
1. A new and distinct variety of grapevine as herein illustrated
and described.
Description
Latin name of the genus and species claimed: Vitis interspecific
hybrid.
Variety denomination: `IFG Twenty-nine`.
BACKGROUND OF THE INVENTION
The new and distinct grapevine described and claimed herein
originated from a hand pollinated cross of the Calinda variety and
Arkansas 2409, an unnamed interspecific hybrid seedless grape
selection, hybridized in May 2002. The abortive seed traces were
subsequently embryo cultured and the resulting sixty-nine plants
were planted in the field in April 2003. The present variety of
grapevine was selected as a single plant in July 2004 and was first
asexually propagated by hardwood cuttings in December 2004. The
resulting propagules were planted during April 2005 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 Twenty-nine` is characterized by producing
extremely narrow elongated seedless fruit with a characteristic
pointed tip. The unusual shape provides consumers with a distinct
visual signal to identify the new variety. The new variety is
further characterized by producing medium firm white fruits which
ripen in midseason season. Berries are moderately crisp in texture,
mild flavored and may have small to medium size rudimentary seed
traces. Bunches are long and are naturally loose so require no
gibberellin for berry thinning. Vines of `IFG Twenty-nine` are
productive. The fruit are naturally large and does not require
treatment with gibberellic acid to obtain satisfactory size. The
new grapevine variety is being introduced to provide home gardeners
with a high quality seedless grape with a distinctive shape.
`IFG Twenty-nine` differs from its maternal parent by producing
very elongated narrow pointed white berries having small to medium
seed traces as opposed to the red elongated fruits having very
large seed traces of the Calinda variety. It differs from its
pollen parent by possessing firmer berries with white coloration as
opposed to the narrow, elongate pointed black fruits of A2409. The
skin of `IFG Twenty-nine` is thinner and the taste is less
herbaceous than the A2409.
BRIEF DESCRIPTION OF THE DRAWING
The accompanying photographic drawing in FIG. 1 illustrates in full
color `IFG Twenty-nine`. 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 left side of
the drawing has mature leaves. A mature fruit cluster is
represented in the center of the drawing along with a typical berry
in cross section. A young shoot can be seen on the right side 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).
