Grapevine named ‘SV27-104-114’

Abstract

A new and distinct variety of grapevine named SV27-104-114 particularly characterized by its unusual, cylindrical shaped berries, medium firm texture, and very large, sweet berries. Additionally, berries of the new cultivar are very responsive to applications of exogenous gibberellic acid and trunk girdling, almost doubling in size in comparison to untreated fruit.

Claims

1. A new and distinct variety of grapevine named SV27-104-114, and parts thereof, substantially as illustrated and described herein.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) 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 a plant about 6 years-old, grown in a field near McFarland, Calif. in 2016.

(2) FIG. 1 Fruit cluster on the vine.

(3) FIG. 2 Fruit and leaves from naturally growing vines and cluster of fruit from a vine to which exogenous gibberellic acid was applied along with trunk girdling.

DETAILED BOTANICAL DESCRIPTION

(4) The following detailed description sets forth the distinctive characteristics of grapevine named SV27-104-114. Descriptions of the new invention apply to vines of grapevine named SV27-104-114 grown on Freedom rootstock at a density of 1,281 vines per hectare grown near McFarland, Calif. in 2017. These vines were in their sixth year of full production having been planted in 2011. 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.
