USPP37036P2 - Grapevine plant named ‘BLOMG06’ - Google Patents

Abstract

Described herein is a new distinct variety of grapevine plant named ‘BLOMG06’. ‘BLOMG06’ is characterized by producing medium sized narrow ellipsoid red berries having very crisp texture with a with a sweet neutral flavor that ripens in late season. Berries are borne on medium size clusters which are loose and do not require gibberellin applications to thin clusters. Gibberellin is required to increase berry size.

Description

Latin name of the genus and species claimed: Vitis vinifera.

Variety denomination: ‘BLOMG06’.

BACKGROUND OF THE INVENTION

Described herein is a new distinct variety of grapevine plant name described ‘BLOMG06’. The ‘BLOMG06’ variety originated from a hand pollinated cross of ‘06143-076-002’ (an unpatented, unreleased numbered selection) and ‘IFG Twenty-four’ (U.S. Plant Pat. No. 28,956) hybridized in May 2013. The abortive seed traces were subsequently embryo cultured, and the resulting 243 seedlings were planted in the field in April 2014. The present variety of grapevine was selected as a single plant in September 2016 and was asexually propagated by hardwood cuttings in December 2016, grafting on ‘Freedom’ (unpatented virus free rootstock), near Delano, Kern County, California. These resulting propagules were planted during April 2017 near Delano, Kern County, California and were found to reproduce true-to-type through at least two generations of asexual propagation.

SUMMARY

The new grapevine plant ‘BLOMG06’ is characterized by producing medium sized narrow ellipsoid red berries having very crisp texture with a sweet neutral flavor. Fruit normally ripens late-season approximately 4-weeks after ‘Thompson Seedless’ (not patented) in California. Berries are borne on medium size clusters which are loose and do not require gibberellin applications to thin clusters. Gibberellin is required to increase berry size. ‘BLOMG06’ stores well. Stems remain green and berries retain their crisp texture and strong flavor for up to eight weeks in cold storage.

‘BLOMG06’ is most similar to ‘Sheegene 20’ (U.S. Plant Pat. No. 23, 125). ‘BLOMG06’ differs from ‘Sheegene 20’ by the natural berry weight, the berry firmness, and the thickness of the skin. ‘BLOMG06’ produces natural berries about 8 g, where ‘Sheegene 20’ produces natural berries about 11.36 g. The texture of the berries of ‘BLOMG06’ is very firm, while the texture of the berries of ‘Sheegene 20’ is firm. The berries of ‘BLOMG06’ have a thin skin (0.7 mm) where the berries of ‘Sheegene 20’ have a medium skin thickness (.

‘BLOMG06’ differs from its maternal parent, ‘IFG Twenty-four’ by maturing several weeks earlier in the growing season, and by having less berry shatter pre-harvest and post-harvest than ‘IFG Twenty-four’. Clusters of ‘BLOMG06’ are smaller than ‘IFG Twenty-four’.

‘BLOMG06’ differs from its seed parent ‘06143-076-002’, by ripening about three to four weeks later, and by having red berries instead of white berries.
