Abstract

A new and distinct grapevine variety is characterized in that it produces a large sized, green, oval berry with a large bunch size. The berries of ‘Sugrafortytwo’ are firm, very juicy, have high sugar content and a fruity flavor. Ripening of the new variety takes place about 1 month earlier than the comparable variety ‘Sugrathirtyfive’ (U.S. Plant Pat. No. 20,491) but the berry has similar shape and appearance. The new variety has an oval berry shape compared to the elongated shape for the comparable variety Thompson (unpatented), with similar ripening.

Description

Latin name of the genus and species claimed: Vitis vinifera.
Variety denomination: ‘SUGRAFORTYTWO’.
BACKGROUND AND SUMMARY OF THE INVENTION
This invention relates to the discovery and asexual propagation of a new and distinct variety of grapevine, ‘Sugrafortytwo’, as herein described and illustrated. The new variety was first hybridized in May 2004 by Michael J. Striem and evaluated in September 2008 by Michael J. Striem and from September 2009 through 2011 by Terry A. Bacon in Wasco, Kern County, Calif. The variety was originated by controlled hybridization.
The new variety ‘Sugrafortytwo’ is characterized by the production of a large sized, green, oval berry with a large bunch size. The berries of ‘Sugrafortytwo’ are firm, very juicy, have high sugar content and a fruity flavor.
The seed parent is the varietal selection ‘97148-027-365’ (unpatented) and the pollen parent is the varietal selection ‘Sugrathirtyone’ (U.S. Plant Pat. No. 19,065). The parent varieties were first crossed in May 2004 by Michael J. Striem. The date of first sowing was March 2005, and the date of first flowering was May 2006.
The new variety ‘Sugrafortytwo’ was first asexually propagated in December 2008 in Wasco, Kern County, Calif., by Michael J. Striem using hardwood cuttings.
The new variety ‘Sugrafortytwo’ differs its seed parent ‘97148-027-365’ (unpatented) in that the new variety ripens about 1 month earlier in the season, and the berry is oval compared to the elongated berry shape of the parent ‘97148-027-365’ (unpatented).
The new variety ‘Sugrafortytwo’ differs from its pollen parent ‘Sugrathirtyone’ (U.S. Plant Pat. No. 19,065) in that the new variety ripens about 1 month earlier in the season.
The new variety ‘Sugrafortytwo’ resembles ‘Thompson’ (unpatented) in that it ripens about the same time. The new variety ‘Sugrafortytwo’ differs from ‘Thompson’ in that the new variety has an oval berry shape compared to an elongated berry shape for ‘Thompson’. The new variety ‘Sugrafortytwo’ resembles ‘Sugrathirtyfive’ (U.S. Plant Pat. No. 20,491) in having the same berry shape and appearance. The new variety ‘Sugrafortytwo’ differs from ‘Sugrathirtyfive’ (U.S. Plant Pat. No. 20,491) in that it ripens about 1 month earlier in the season.
The new ‘Sugrafortytwo’ 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 any of a variety of factors such as growing conditions, irrigation, fertilization, pruning, management and with 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 ‘Sugrafortytwo’.
The illustration shows the upper and lower surface of the leaves and exterior and sectional view 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 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 ‘Sugrafortytwo’ plants grown in the vicinity of Wasco, Kern County, Calif. during 2011, and is believed to apply to plants of the variety grown under similar conditions of soil and climate elsewhere.
