Grapevine plant named ‘SV22-88e-124’

Abstract

A new and distinct variety of grapevine plant named SV22-88e-124 particularly characterized by its amber colored berries with sweet, aromatic flavor similar to spun sugar. Additionally, berries of the new cultivar are very responsive to applications of exogenous gibberellic acid, producing looser clusters with larger berries compared to untreated clusters.

Claims

1. A new and distinct variety of grapevine plant named SV22-88e-124, 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 5 years-old, grown in a field near McFarland, Calif. in 2016.

(2) FIG. 1 Leaves and stems with natural fruit cluster on the left and fruit cluster from vine to which exogenous gibberellic acid was applied.

(3) FIG. 2 Fruit on vine to which exogenous gibberellic acid was applied with vine girdling.

DETAILED BOTANICAL DESCRIPTION

(4) The following detailed description sets forth the distinctive characteristics of SV22-88e-124. Descriptions of the new invention apply to vines of SV22-88e-124 grown on Freedom rootstock at a density of 1,537 vines per hectare grown near McFarland, Calif. in 2017. These vines were in their fifth year of full production having been planted in 2012. These descriptions are believed to apply generally to the new variety grown under similar circumstances elsewhere. Variance from some of these traits may be expected depending upon cultural practices including fruit load as well season to season temperature variation.
