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 plants about 5 years old grown near McFarland, Calif. in 2020 and 2021.

(2) FIG. 1 Fruit clusters on seedling vine at time of selection.

(3) FIG. 2 Vine and clusters treated with exogenous gibberellic acid and trunk girdling.

(4) FIG. 3 Natural fruit cluster (left), fruit cluster treated with gibberellic acid (right), shoots, leaves and tendrils.

DETAILED BOTANICAL DESCRIPTION

(5) The following detailed description sets forth the distinctive characteristics of grapevine named ‘SV33-101-337’. Descriptions of the new invention apply to vines of ‘SV33-101-337’ grown on ‘Freedom’ (unpatented) rootstock at a density of 1,537 vines per hectare grown near McFarland, Calif. in 2021. These vines were in their fifth year of full 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.
