Abstract

A new and distinct grapevine variety denominated ‘INIA-G3’. The new grapevine is characterized by producing muscat flavored berries, that are ovoid, red, with firm texture, small seed traces and midseason ripening. The clusters are abundant in the vine, large in size and naturally loose, with good keeping and shipping quality.

Description

Latin name: Vitis vinifera L.
Varietal denomination: ‘INIA-G3’.
BACKGROUND
The present invention relates to the discovery and asexual propagation of a new variety of grapevine, Vitis vinifera L. denominated ‘INIA-G3’. This new cultivar resulted from controlled hybridization between ‘Moscatel Rosado’ (♀, unpatented) and ‘Emperatriz’ (♂, U.S. Plant Pat. No. 5,833) performed at latitude 33°35°58′02″S 72°18′56″O, corroborated by molecular markers techniques. The maternal parent ‘Moscatel Rosado’ was emasculated and hand pollinated with pollen from ‘Emperatriz’. Plants were produced from maternal parent ‘Moscatel Rosado’ seeds. Specifically, the seeds were germinated and planted in Cauquenes, Chile. The new variety ‘INIA-G3’ was selected and asexually propagated from dormant cuttings in Cauquenes, Chile. In 2006, ‘INIA-G3’ was introduced to latitude 33°34′18″S, 70°37′46″W for its agronomical characterization.
SUMMARY
‘INIA-G3’ produces firm, ovoid, red berries with muscat flavor. Berries are small-medium in size reaching about 3.8 gr. Berry size can be moderately increased with application of gibberellic acid. Berries are mostly seedless, but in occasions could develop rudimentary soft seed traces of medium size. The clusters are abundant in the vine, large in size, conical and loose in density. After cluster pruning for exportation, they usually reach 550 g. The fruit has an export market potential for having good keeping and shipping quality. Vines are vigorous and strong. Because its high bud fruitfulness at the basal buds, spur pruning may be used.
‘INIA-G3’ is most similar to ‘Moscatel seedless’ (unpatented). ‘INIA-G3’ differs from this variety by having berries with firmer pulp. It also differs by having bigger and looser clusters. ‘INIA-G3’ is different from its maternal parent ‘Moscatel Rosado’ by having rudimentary seeds instead of complete seeds. INIA-G3 differs from its paternal parent ‘Emperatriz’ by berry clusters as INIA-G3 clusters are more abundant and less variable in berry size. The new variety also has a better shipping and storage quality. ‘INIA-G3’ could also be compared with ‘Crimson Seedless’ (unpatented), but differs by having smaller berries and muscat flavor.
The new ‘INIA-G3’ variety has shown to maintain its distinguishing characteristics through successive asexual propagation by, for example, cuttings.
