Abstract

A new and distinct grapevine variety ‘Sugrafiftythree’ is characterized by an early ripening, broad elliptic, dark-red berry, and a large berry and cluster weight. The berries of ‘Sugrafiftythree’ are very firm.

Description

Latin name of the genus and species claimed: Vitis vinifera.
Variety denomination: ‘SUGRAFIFTYTHREE’.
BACKGROUND AND SUMMARY OF THE INVENTION
This application relates to the discovery and asexual propagation of a new and distinct variety of grapevine, ‘Sugrafiftythree’, as herein described and illustrated. The new variety was first selected as breeder number ‘GR604R’ by Terry A. Bacon in Wasco, Kern County, Calif. in July 2016. The variety was originated by controlled hybridization.
The new variety ‘Sugrafiftythree’ is characterized by broad, elliptic, early ripening, dark-red berries, having a large berry and cluster weight. The berries of ‘Sugrafiftythree’ are very firm.
The seed parent is the varietal selection ‘04006-199-045’ (unpatented) and the pollen parent is the varietal selection ‘GR363W’ (unpatented breeding selection). The parent varieties were first crossed in April 2014. The date of first sowing was March 2015, and the date of first flowering was April 2016.
The new variety ‘Sugrafiftythree’ was first asexually propagated in December 2016 in Wasco, Kern County, Calif., by Terry A. Bacon using hardwood cuttings.
The new variety ‘Sugrafiftythree’ differs from its seed parent ‘04006-199-045’ in that the new variety has red berries compared to green berries for ‘04006-199-045’.
The new variety ‘Sugrafiftythree’ differs from its pollen parent ‘GR363W’ (unpatented) in that the new variety has red berries compared to green berries for ‘GR363W’.
The new variety ‘Sugrafiftythree’ has a similar red berry color as ‘Flame Seedless’ (unpatented), but the berries of the new variety ‘Sugrafiftythree’ have a broad elliptic shape compared to a round shape for ‘Flame Seedless’. The new variety ‘Sugrafiftythree’ has a similar red berry color as ‘Sheegene-12’ (U.S. Plant Pat. No. 20,252), but ripening of the berries of the new variety ‘Sugrafiftythree’ starts about June 29 compared to about August 1 for ‘Sheegene-12’.
The new ‘Sugrafiftythree’ variety has been shown to maintain its distinguishing characteristics through successive asexual propagations by, for example, cuttings and grafting.
Variations of the usual magnitude from the characteristics described herein may occur with changes in any of a variety of factors such as growing conditions, irrigation, fertilization, pruning, management and climatic variation.
BRIEF DESCRIPTION OF THE DRAWING
The accompanying color photographic illustration shows typical specimens of the foliage and fruit of the present new grape variety ‘Sugrafiftythree’. The illustration shows the upper and lower surfaces of the leaves and exterior and sectional views of the fruit. The photographic illustration was taken shortly after the fruit was picked and the colors are as nearly true as is reasonably possible in a color representation of this type.
 DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
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 The R.H.S. Colour Chart, published by The Royal Horticultural Society, London, England, 1986.
Many of the descriptive values in this specification are based on and conform to those set forth by the International Board for Plant Genetic Resources Institute Grape Descriptors (Vitis spp.) of 1983 and/or 1997, 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).
