Abstract

A new and distinct grapevine variety characterized by producing large, uniform, clusters with large oval berries. The berries have a medium sugar content and neutral flavor. The berries are larger than the comparable variety Crimson seedless and the red color of the berries develops more uniformly, leading to a shorter harvest window.

Description

Latin name of the genus and species claimed: Vitis vinifera.
Variety denomination: ‘SUGRATHIRTYEIGHT’.
BACKGROUND AND SUMMARY OF THE INVENTION
This invention relates to the discovery and asexual propagation of a new and distinct variety of grapevine, ‘Sugrathirtyeight’, as herein described and illustrated. The new variety was first hybridized by Michael Striem in Wasco, Kern County, Calif., the variety being originated by controlled hybridization.
The new variety ‘Sugrathirtyeight’ is characterized by producing oval berries with uniform red colored berry skin. The berries of ‘Sugrathirtyeight’ have medium sugar content and a neutral flavor.
The seed parent is the varietal selection ‘98127-111-153’ (unpatented) and the pollen parent is the varietal selection ‘94190-162-345’ (unpatented). The parent varieties were first crossed in May 2004 by Michael Striem. The date of first sowing was March 2005, and the date of first flowering was May 2006.
The new variety ‘Sugrathirtyeight’ was first asexually propagated in January 2007, in Wasco, Kern County, Calif., by Michael Striem using hardwood cuttings.
The new variety ‘Sugrathirtyeight’ differs from its seed parent ‘98127-111-153’(unpatented) in that it has red berries rather than green berries.
The new variety ‘Sugrathirtyeight’ resembles its pollen parent ‘94190-162-345’ (unpatented) in that both have red berries, but differs from its pollen parent in that harvest starts earlier for the new variety, usually about August 10 in California's San Joaquin Valley, compared to October 1st for the pollen parent, ‘94190-162-345.’
Harvest of the new variety starts about the same time as for the red grape cultivar ‘Crimson Seedless’ (unpatented), but the red color of the new variety develops more uniformly so that the harvest window can be shorter than ‘Crimson Seedless’ (20 days for the new variety vs 60 days for ‘Crimson Seedless’ in California's San Joaquin Valley). The new variety also has an oval berry shape compared to elongated for ‘Crimson Seedless’ and the berry diameter is larger than ‘Crimson Seedless’ at 23 mm for the new variety vs 18 mm for ‘Crimson Seedless’.
The new ‘Sugrathirtyeight’ variety has been shown to maintain its distinguishing characteristics through successive asexual propagations by, for example, cuttings.
Variations of the usual magnitude from the characteristics described herein may occur with changes in growing conditions, irrigation, fertilization, pruning, management and with climatic variation.
BRIEF DESCRIPTION OF THE DRAWINGS
The accompanying drawing in FIG. 1 illustrates in full color a typical cluster of berries, a young shoot, and a mature leaf blade of the new grapevine. 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.
Many of the description 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).
The descriptive matter which follows pertains to ‘Sugrathirtyeight’ plants grown in the vicinity of Wasco, Kern County, Calif., during 2010, and is believed to apply to plants of the variety grown under similar conditions of soil and climate elsewhere.
