STATEMENT OF ANY FEDERALLY-SPONSORED RESEARCH AND DEVELOPMENT

The present invention is not subject of Federally-sponsored research or development.

BACKGROUND OF THE INVENTION

The present invention comprises a new and distinct cultivar of grapevine botanically known as Vitis vinifera and hereinafter referred to as grapevine named ‘SV30-27-602’. As used herein, ‘grapevine’ refers to all plant parts including vines, canes, tendrils, leaves, fruit and roots of ‘SV30-27-602’. Grapevine named ‘SV30-27-602’ is the result of an effort to produce a late ripening red, seedless table grape with fruit characteristics superior to currently available cultivar ‘Scarlet Royal’ (U.S. Plant Pat. No. 16,229). This cultivar resulted from a cross made in April 2009 between female grapevine named ‘SV16-76-232’ (unpatented) and male grapevine plant named ‘SV21-66-226’ (U.S. Plant Pat. No. 24,531). Resultant seeds were harvested in October 2009 and were stratified under refrigeration at 2 degrees Celsius. The seeds were planted in soil in the greenhouse in January 2010 and resultant seedlings were grown in the greenhouse until April 2010. The seedlings were transplanted to a field north of Delano, Calif. in that same month and were trained to a trellis that same year. Fruit of the seedling were observed on Aug. 9, 2013 at which time the selection for trialling was made. Woody cuttings were harvested in December of 2013 and buds of grapevine named ‘SV30-27-602’ were bench grafted to ‘Freedom’ (unpatented) rootstock. The resultant plants were planted in a trial location near McFarland, Calif. in May of 2014 and were trained to a t-trellis on 7 foot by 10 foot spacing. The present invention has been found to retain its distinctive characteristics through three successive asexual propagations.

Grapevine named ‘SV30-27-602’ differs from its female parent, grapevine named ‘SV16-76-232’ (unpatented), in that ‘SV30-27-602’ is stenospermocarpic with small seed traces while ‘SV16-76-232’ has fully developed, functional seeds.

Grapevine named ‘SV30-27-602’ differs from its male parent, ‘SV21-66-226’ (U.S. Plant Pat. No. 24,531), in that ‘SV30-27-602’ produces red skinned ellipsoidal grapes while ‘SV21-66-226’ produces green skinned grapes.

Grapevine named ‘SV30-27-602’ most closely resembles ‘Scarlet Royal’ (U.S. Plant Pat. No. 16,229) but it may be distinguished from ‘Scarlet Royal’ because ‘SV30-27-60’ produces berries with a much brighter red color than the dark red berries produced by ‘Scarlet Royal’. Additionally, grapevine named ‘SV30-27-602’ produces berries with distinct muscat flavor and no astringency while ‘Scarlet Royal’ (U.S. Plant Pat. No. 16,229) berries develop astringency at full ripeness.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishing characteristics of this new cultivar when grown under normal horticultural practices near McFarland, Calif.:

- 1. Red skinned berries;
- 2. Firm berry texture; and
- 3. Large, ellipsoidal shaped berries with muscat flavor.

BRIEF DESCRIPTION OF THE DRAWINGS

This new grapevine is illustrated by the accompanying photographs which show fruit clusters, leaves, canes and tendrils. The colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photographs were taken from plants about 5 years old, grown in a field near McFarland, Calif. in 2019.

DETAILED BOTANICAL DESCRIPTION

The following detailed description sets forth the distinctive characteristics of grapevine named ‘SV30-27-602’. Descriptions of the new invention apply to vines of grapevine named ‘SV30-27-602’ grown on ‘Freedom’ (unpatented) rootstock at a density of 1,537 vines per hectare grown near McFarland, Calif. in 2019. These vines were in their fourth year of full production having been planted in 2014. These descriptions are believed to apply generally to the new variety grown under similar circumstances elsewhere. Color references are primarily to The Royal Horticultural Society's Colour Chart, The Royal Horticultural Society, London, United Kingdom (copyright 2001). Descriptors used herein conform to those set forth by the International Board for Plant Genetic Resources Institute Grape Descriptors (Vitis spp.) of 1983 and/or 1997 which were developed in collaboration with the Office International de la Vigne et du Vin (OIV) and the International Union for the Protection of New Varieties (UPOV) and published in Descriptors for Grapevine (Vitis spp.) (Anonymous, International Plant Genetic Resources Institute, 1997, ISBN 92-9043-352-3).
