Abstract

A new and distinct variety of grapevine plant named ‘SV30-13-10’ particularly characterized by its ellipsoidal to ovate shaped, seedless, red skinned berries which are medium-large, sweet, with a fruity Vitis labrusca flavor and which have tender texture. Productivity is high, with spur pruning only needed for a full crop.

Variety denomination: The plant claimed shall be known as ‘SV30-13-10’.

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 ‘SV30-13-10’. As used herein, ‘grapevine’ refers to all plant parts including, vines, canes, tendrils, leaves, fruit and roots of ‘SV30-13-10’. Grapevine named ‘SV30-13-10’ is the result of an effort to produce a red, seedless table grape with fruit characteristics superior to currently available red skinned grape cultivar ‘Scarlet Royal’ (U.S. Plant Pat. No. 16,229). This new cultivar originated from a cross conducted in May 2009 near McFarland, Calif. between grapevine plant selection ‘SV16-72-83’ (unpatented) and pollen parent ‘SV21-66-158’ (U.S. Plant Pat. No. 24,510). Resultant ovules from the cross were harvested 42 days after pollination and cultured on ‘McCown's Woody Plant Medium’ at a temperature of 22° C. for twelve weeks. Subsequently, the resultant embryonic plants were cultured in the same medium in the laboratory under twelve hours of light from standard fluorescent lamps at 26.4° C. The seedlings from this effort were transplanted to the greenhouse in October of 2010 and grown in the greenhouse at 26.4° C. with 12 hours' illumination under high pressure sodium vapor lamps. The seedling population of 315 plants was planted in the field in the spring of 2010 near Delano, Calif. The new grapevine was selected from this seedling population on Jul. 11, 2012. It was then propagated by cuttings and bench grafted to ‘Freedom’ (unpatented) rootstock in 2013. The present invention has been found to retain its distinctive characteristics through two successive asexual propagations.

Grapevine named ‘SV30-13-10’ differs from the female parent grapevine ‘SV16-72-83’ (unpatented) in that grapevine named ‘SV30-13-10’ has ovate shaped, dark red to black skinned, seedless berries, whereas ‘SV16-72-83’ (unpatented) has ovate shaped, black skinned berries with partially lignified seed traces and some epidermal reticulation.

Grapevine named ‘SV30-13-10’ differs from its male parent ‘SV21-66-158’ (U.S. Plant Pat. No. 24,510) in that grapevine named ‘SV30-13-10’ has dark red to black skinned berries while ‘SV21-66-158’ (U.S. Plant Pat. No. 24,510) has green skinned berries.

Grapevine named ‘SV30-13-10’ differs from the commercial cultivar ‘Scarlet Royal’ (U.S. Plant Pat. No. 16,229) in that grapevine named ‘SV30-13-10’ produces berries with no astringent flavour whereas ‘Scarlet Royal’ (U.S. Plant Pat. No. 16,229) produces berries at full ripeness which are astringent. Additionally, grapevine named ‘SV30-13-10’ produces berries which are very glossy/shiny due to absence of translucent, waxy bloom.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishing characteristics of the ripe fruit of this new variety when grown under normal horticultural practices near McFarland, Calif. Some of the characteristics may vary depending upon changes in crop load and change of location of cultivation.

- 1. Dark red to black skinned fruit;
- 2. Very firm berry texture;
- 3. Large, ovate shaped berries with mild, sweet flavor; and
- 4. Berries which lack the typical translucent layer of wax found on grapes at maturity and which are very shiny in appearance.

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 in 2012 on the seedling vine and in 2018 from a plant about 5 years-old, grown in a field near McFarland, Calif.

DETAILED BOTANICAL DESCRIPTION

The following detailed description sets forth the distinctive characteristics of grapevine named ‘SV30-13-10’. Descriptions of the new invention apply to vines of grapevine named ‘SV30-13-10’ grown on ‘Freedom’ (unpatented) rootstock at a density of 1,537 vines per hectare grown near McFarland, Calif. in 2018. These vines were in their fourth year of full production, having been planted in 2013. These descriptions are believed to apply generally to the new variety grown under similar circumstances elsewhere. References to color correspond to The Royal Horticultural Society's Colour Chart, The Royal Horticultural Society, London, United Kingdom. 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 Interantional de la Vigne et du Vin (OIV) and the International Union for the Protection of New Varieties of Plants (UPOV) and published in Descriptors for Grapevine (Vitis spp.) (Anonymous, International Plant Genetic Resources Institute, 1997, ISBN 92-9043-352-3).
