Variety denomination: The plant claimed shall be known as ‘SV33-82-49’.

STATEMENT OF ANY FEDERALLY-SPONSORED RESEARCH AND DEVELOPMENT

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

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of grapevine botanically known as Vitis vinifera L. and hereinafter referred to as grapevine named ‘SV 33-82-49’. As used herein, ‘grapevine’ refers to all plant parts including vines, shoots, canes, tendrils, leaves, fruit and roots of ‘SV33-82-49’. Grapevine named ‘SV33-82-49’ is the result of an effort to produce an early ripening, black, seedless table grape with fruit characteristics and productivity superior to currently available black, seedless cultivar ‘Summer Royal’ (unpatented). This new cultivar originated from a cross conducted in May 2012 near McFarland, Calif. between female parent grapevine selection ‘SV17-50-583’ (unpatented) and male parent grapevine selection ‘SV21-66-226’ (U.S. Plant Pat. No. 24,531). Resultant ovules from the cross were harvested 42 days after pollination and cultured on ‘McCown's Woody Plant Medium’. Subsequently, the resultant embryonic plants were cultured in the same medium in the laboratory under twelve hours of light from standard fluorescent lamps at 29° C. The seedlings from this effort were transplanted to the greenhouse in October of 2012 and grown in the greenhouse at 29° C. with 12 hours illumination under high pressure sodium vapor lamps. The seedling population of 327 plants was planted in the field in the spring of 2013 near Delano, Calif. The new grapevine was selected from this seedling population on Aug. 21, 2015. It was then propagated by cuttings and grafted to ‘Freedom’ (unpatented) rootstock in 2016. The resultant vines were planted in a trial near McFarland, Calif. in May of 2016 and were trained to a t-trellis on 2.1 meter by 3 meter spacing. The present invention has been found to retain its distinctive characteristics through two successive asexual propagations.

Grapevine named ‘SV33-82-49’ differs from its female parent grapevine named ‘SV17-50-583’ (unpatented) in that ‘SV33-82-49’ has berries with small, soft seed traces less than 1 mm in length while ‘SV17-50-583’ has partially lignified seed traces about 3 mm in length.

Grapevine named ‘SV33-82-49’ differs from its male parent grapevine named ‘SV21-66-226’ (U.S. Plant Pat. No. 24,531) in that ‘SV33-82-49’ has black berries while ‘SV21-6-226’ produces berries which are green.

Grapevine named ‘SV33-82-49’ most closely resembles commercially available cultivar ‘Autumn Royal’ (unpatented) but differs from it in that grapevine ‘SV33-82-49’ produces clusters of fruit which ripen in mid-July while ‘Autumn Royal’ clusters ripen in late August in the Delano, California area.

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, California:

- a. Berries with black skin.
- b. Very firm berry texture and sweet, neutral flavor;
- c. Berries which are responsive to gibberellic acid and trunk girdling applications.
- d. Abundant, medium-sized bunches which ripen in mid-July in McFarland, California.

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 near McFarland, Calif. in 2024.

DETAILED BOTANICAL DESCRIPTION

The following detailed description sets forth the distinctive characteristics of grapevine named ‘SV33-82-49’. Descriptions of the new invention apply to vines of grapevine named ‘SV33-82-49’ grown on ‘Freedom’ (unpatented) rootstock at a density of 1,537 vines per hectare grown near McFarland, California in August 2023. These vines were in their sixth year of production having been planted in 2016. These descriptions are believed to apply generally to the new variety grown under similar circumstances elsewhere. Variation due to soil and climatic conditions in other locations may be seen.
