Abstract

This invention is a new and distinctive grapevine ‘IFG 31-077’. ‘IFG 31-077’ produces large, elongated, fully black, naturally large seedless fruits that ripen early and possess high sugar content and superior eating quality. The clusters have strong stems with good berry attachment.

Description

Latin name of the genus and species of the plant claimed: Vitis vinifera.
Variety denomination: ‘IFG 31-077’.
BACKGROUND OF THE INVENTION
The new and distinct grapevine described and claimed herein originated from a hand pollinated cross of the Summer Royal variety (non-patented) and the Regal variety (South African PBR ZA971795)) hybridized in May 2001. The abortive seed traces were subsequently embryo cultured and the resulting population of plants were planted in the field in April 2002. The present variety of grapevine was selected as a single plant from within a population of 106 plants in July 2003 and was first asexually propagated by hardwood cuttings in December 2003. 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
‘IFG 31-077’ was selected on the basis of a unique grouping of characteristics, including the ability to produce large, elongated, fully black, naturally large seedless fruits that ripen early and possess high sugar content and superior eating quality. The clusters have strong stems with good berry attachment.
To the inventor's knowledge, the known varieties to which the new grapevine variety is most similar are the parent varieties, the Sugrathirteen variety (U.S. Plant Pat. No. 10,434), and the Mariah variety (U.S. Plant Pat. No. 9,040). ‘IFG 31-077’ can be distinguished from these varieties based on the unique combination of characteristics for which it was selected. ‘IFG 31-077’ can further be distinguished from these known varieties as follows.
‘IFG 31-077’ can be distinguished from its parent the Summer Royal (non-patented) variety by having much more elongated berries as opposed to the nearly round berries of Summer Royal. The new variety ripens 7 days or more before the Summer Royal variety. The vine of the new variety is more vigorous and robust than the vine of the Summer Royal variety.
‘IFG 31-077’ differs from its parent the Regal variety by possessing black rather than white fruits. Berries of the new variety are slightly less elongated than the Regal variety. Berries of the new variety more readily attain high sugar content and are of superior eating quality as compared to the Regal variety.
‘IFG 31-077’ most closely resembles the Sugrathirteen variety in having somewhat similar color, fruit shape and an early ripening period. The new variety differs from the Sugrathirteen variety by having darker more fully black fruits that will attain full color even under low light conditions thus requiring less manipulation of the canopy to obtain commercially acceptable color. The new variety possesses slightly smaller berry size and berries are slightly softer and juicier. The new variety more readily attains high sugar content and has somewhat more acid giving a better sugar acid balance.
‘IFG 31-077’ somewhat resembles the Mariah variety however it differs from the Mariah variety by having a larger average berry size (6.1 g vs. 4.8 g). The new variety can further be distinguished from the Mariah variety by having more elongated and narrower berry as opposed to the shorter more nearly round berries of the Mariah variety. The new variety is responsive to gibberellic acid application to reduce berry number and increase berry size and does not show phytotoxicity to normal levels of gibberellic acid.
BRIEF DESCRIPTION OF THE DRAWINGS
The accompanying photographic illustration in FIG. 1 illustrates in full color ‘IFG 31-077’. The photograph was taken using conventional techniques. The colors are as nearly true as is reasonably possible in a color representation of this type.
 DETAILED 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 by The Royal Horitcultural 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).
The following descriptive matter pertains to ‘IFG 31-077’ plants grown in the vicinity of Delano, Kern County, Calif. during 2007–2008, and is believed to apply to plants of the variety grown under similar conditions of soil and climate elsewhere.
