Abstract

This invention is a new and distinct grapevine variety denominated ‘IFG Thirty-seven’. The new grapevine is characterized by producing naturally large seedless red berries having a broad ellipsoidal shape with a mild labrusca flavor. Fruits have medium firm texture and have excellent eating quality. Berries color readily even in hot climatic conditions and produce completely colored red berries. Vines are productive and can be pruned to short spurs. Berries are borne on large, loose but well filled clusters that do not require any additional thinning.

Description

Latin name of the genus and species claimed: Vitis interspecific hybrid.
Variety denomination: ‘IFG Thirty-seven’.
BACKGROUND OF THE INVENTION
The new and distinct grapevine plant described and claimed herein originated from a hand pollinated cross of ‘01161-040-184’ (unnamed Vitis vinifera selection from the IFG breeding program), and ‘IFG Thirty-four’ (U.S. Plant Pat. No. 30,325) hybridized in May 2008. The abortive seed traces were subsequently embryo cultured and the resulting 245 plants were planted in the field in April 2009. The present variety of grapevine was selected as a single plant in September 2011 and was first asexually propagated by hardwood cuttings in December 2011 near Delano, Kern County, Calif. These cuttings produced second generation plants that were planted during April 2012 near Delano, Kern County, Calif. and were observed for at least four years and found to be true-to-type.
BRIEF SUMMARY OF THE INVENTION
The new grapevine plant ‘IFG Thirty-seven’ is characterized by producing naturally large seedless red berries having a broad ellipsoidal shape with a mild labrusca flavor. Fruits have medium firm texture and have excellent eating quality. Berries color readily even in hot climatic conditions and produce completely colored red berries. Vines are productive and can be pruned to short spurs. Berries are borne on large, loose but well filled clusters that do not require any additional thinning. Berry size is naturally large but can be increased by applying gibberellic acid. The fruit stores well for up to eight weeks under commercial conditions.
‘IFG Thirty-seven’ can be distinguished from its maternal parent, the 01161-040-184, by having larger berry size, less firm flesh, having red instead of reddish black skin color and by having a mild fruity labrusca flavor as opposed to the neutral vinifera flavor of 01161-040-184.
The new grapevine differs from its pollen parent the ‘IFG Thirty-four’ by having brighter red rather than reddish black to black berry color; by having a broad ellipsoidal rather than round shape and by having much larger natural berry size and by having a larger cluster size and firmer berries.
‘IFG Thirty-seven’ is most similar to ‘IFG Nineteen’ (U.S. Plant Pat. No. 26,121) but differs by having a less vigorous growth habit, having smaller, more deeply lobed leaves, by having larger natural berries that have a mild labrusca flavor rather than a strong muscat/labrusca flavor of the ‘IFG Nineteen’. ‘IFG Thirty-seven’ colors more easily than ‘IFG Nineteen’ does in hot climates.
‘IFG Thirty-seven’ is somewhat similar to its sibling the ‘IFG Twenty-two’ (U.S. Plant Pat. No. 26,541) but differs from ‘IFG Twenty-two’ by having a larger berry size, a broad ellipsoidal berry shape as opposed to a round to slightly elliptic shape of ‘IFG Twenty-two’, and having red rather than black berry color black color. It also has a milder flavor.
‘IFG Thirty-seven’ is also somewhat similar to its other sibling, ‘IFG Thirty-six’ (Plant patent application Ser. No. 15/932,108) filed concurrently with ‘IFG Thirty-seven’ (Plant patent application Ser. No. 15/932,107). It differs from the ‘IFG Thirty-six’ by having red rather than black berry color and by having a milder, more fruity flavor.
BRIEF DESCRIPTION OF THE DRAWING
The accompanying photographic drawing in FIG. 1 illustrates in full color ‘IFG Thirty-seven’, 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 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 2015 by The Royal Horticultural Society, London, England.
Throughout this specification, subjective description values conform to those set forth by the UPOV International Union for the Protection of New Varieties of Plants publication ‘Grapevine Vitis L. Guidelines’.
