Grapevine named SV35-182-214

Abstract

A new and distinct variety of grapevine plant named ‘SV35-182-214’ particularly characterized by medium sized clusters of green skinned berries which are large, crisp, and sweet with muscat flavor. The vines are very responsive to exogenous gibberellic acid application and trunk girdling which induces a size increase of the berries more than double the natural size. Vines are fruitful when spur pruned to two buds per cane with new shoots producing one or two clusters per shoot.

Claims

1. A new and distinct variety of grapevine plant named ‘SV35-182-214’, 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 the original seedling vine in 2017. The remainder of the photographs were taken from a vine grafted to ‘Freedom’ (unpatented) rootstock in 2020 and 2021.

(2) FIG. 1 Fruit cluster on the seedling vine taken in July 2017.

(3) FIG. 2 Fruit cluster from vine which was treated with gibberellic acid and trunk girdling taken in 2021.

(4) FIG. 3 Cane, leaves, tendrils and shoot tip from vine treated with gibberellic acid and trunk girdling. Natural fruit cluster at left and fruit cluster from vine treated with gibberellic acid and trunk girdling, right, taken in 2021.

(5) FIG. 4. Fruit clusters on vine treated with gibberellic acid and trunk girdling, taken on the day of harvest, Aug. 18, 2021.

DETAILED BOTANICAL DESCRIPTION

(6) The following detailed description sets forth the distinctive characteristics of grapevine named ‘SV35-182-214’. Descriptions of the new invention apply to vines of grapevine named ‘SV35-182-214’ grown on ‘Freedom’ (unpatented) rootstock at a density of 1,537 vines per hectare grown near McFarland, Calif. in 2020 and 2021. These vines were observed two years following planting and in the following year, having been planted in 2018. These descriptions are believed to apply generally to the new cultivar grown under similar circumstances elsewhere.
