Abstract

‘BLOMG05’ is a new and distinct grapevine variety characterized by producing medium sized broadly ellipsoid red berries having very crisp texture with a with a strong fruity flavor combining characteristics of muscat and labrusca which ripens in mid-season. Berries are borne on medium size clusters which are loose and do not need gibberellin applications to thin clusters. Gibberellin is required to increase berry size.

Description

Latin name of the genus and species: Vitis vinifera interspecies hybrid.

Variety denomination: ‘BLOMG05’.

BACKGROUND

Described herein is a new and distinct grapevine plant that originated from a hand pollinated cross of ‘IFG Nineteen’ (U.S. Plant Pat. No. 26,121) and 06156-071-205 (an unpatented, unreleased numbered selection) hybridized in May 2014. The abortive seed traces were subsequently embryo cultured, and the resulting 72 seedlings were planted in the field in April 2015. The present variety of grapevine was selected as a single plant in August 2017 and was asexually propagated by hardwood cuttings grafted on Freedom (unpatented virus free rootstock) in December 2017, near Delano, Kern County, California. These resulting propagules were planted during April 2018 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 ‘BLOMG05’ is characterized by producing medium sized broadly ellipsoid red berries having very crisp texture with a strong fruity flavor combining characteristics of muscat and labrusca. Fruit normally ripens mid-season similar in timing to 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. ‘BLOMG05’ stores well. Stems remain green and berries retain their crisp texture and strong flavor for up to eight weeks in cold storage. To the inventor's knowledge, the known variety to which the new grapevine variety is most similar is ‘IFG Nineteen’. ‘BLOMG05’ differs from ‘IFG Nineteen’ by having much crisper berry texture, better color development, and less berry shatter pre-harvest and post-harvest.

‘BLOMG05’ differs from its maternal parent, ‘IFG Nineteen’ by producing much crisper textured berries, and by producing more intense red pigmentation than ‘IFG Nineteen’. Clusters of ‘BLOMG05’ are shorter and smaller than ‘IFG Nineteen’. It differs from its pollen parent, 06156-071-205 (not patented) by ripening about three to four weeks later, by having smaller natural berry size with no distinct flavor, and by having white berries.

BRIEF DESCRIPTION OF THE DRAWINGS OR PHOTOGRAPHS

The colored photographs illustrate the overall appearance of the ‘BLOMG05’ plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description that accurately describe the colors of the plant described herein. These figures are exemplary and will vary depending on the plant and distinguishing characteristics.

FIG. 1 illustrates ‘BLOMG05’. The photograph was taken outdoors with indirect lighting. The left side of the drawing has a mature leaf. A mature fruit cluster is represented in the center of the drawing along with a typical berry in cross section. A young shoot tip can be seen on the right side of the drawing.
