Abstract

‘BLOMG01’ is a new and distinct grapevine plant with novel characteristics that include good fertility and excellent fruity labrusca-toffee like flavor. The berries produced by ‘BLOMG01’ are yellowish green and seeded, with a very firm and crunchy texture. The berries produced by ‘BLOMG01’ are large, weighing 6.5 g/berry on average, and harvested in early July in Murcia Region (Spain).

Description

Latin name of the genus and species: Vitis vinifera.

Variety denomination: ‘BLOMG01’.

BACKGROUND

Described herein is a new distinct variety of grapevine named ‘BLOMG01’. The variety originated from a hybridization performed in Murcia, Spain during 2017 between ‘Princess’ (unpatented), as the pollen parent, and ‘New York Muscat’ (unpatented), as the seed parent. Abortive seed traces were embryo cultured and the resulting plant was planted in an evaluation block during 2018. The first evaluation of the fruit produced by ‘BLOMG01’ was performed during 2019. ‘BLOMG01’ was first asexually propagated by field grafting dormant hardwood scions to rootstock in 2020 in Murcia, Spain. Fruit from the resulting four grafted ‘BLOMG01’ vines was first harvested in 2021. All characteristics and distinctions remain true to form and are established and transmitted through succeeding propagations.

SUMMARY

The following are the most outstanding and distinguishing characteristics of ‘BLOMG01’. ‘BLOMG01’ produces naturally large (6.5 g/berry), seeded, yellow green (2.5 GY 7/8) berries having a broad ellipsoid shape with an excellent unique fruity labrusca-toffee like flavor, very firm texture, and a high fertility index (1.3), that are harvested in early July, in Murcia, Spain.

‘BLOMG01’ is believed to be most similar to ‘IFG Seven’ (U.S. Plant Pat. No. 23,399). Nonetheless, the new cultivar can be distinguished from ‘IFG Seven’ based at least upon harvest period, berry shape, berry size and fertility index. ‘BLOMG01’ matures in early July while ‘IFG Seven’ matures in August-September. The berries produced by ‘BLOMG01’ have a broad ellipsoid shape while the berries produced by ‘IFG Seven’ have an elliptic-obtuse ovate shape, and the berries of ‘BLOMG01’ are smaller than the berries of ‘IFG Seven’ (6.5 g v. 9.7 g). ‘BLOMG01’ has a higher fertility index than ‘IFG Seven’ (1.3 v. 0.9-1.0).

‘BLOMG01’ can be distinguished from its male parent, ‘Princess’ (unpatented), in that the new cultivar has a harvesting time in early July, whereas ‘Princess’ has a harvest time in August-September. The berries of ‘BLOMG01’ have a labrusca-toffee like flavor while the berries of ‘Princess’ have a light muscat flavor. ‘BLOMG01’ has a higher fertility index than ‘Princess’ (1.3 v. 1.0).

‘BLOMG01’ can be distinguished from its female parent, ‘New York Muscat’ (unpatented), in that the new cultivar, ‘BLOMG01’, produces white (2.5GY7/8) colored grapes while ‘New York Muscat’ produces violet grapes. The berries of ‘BLOMG01’ have a firm texture whereas the berries of ‘New York Muscat’ have a soft texture. The berries of ‘BLOMG01’ have a labrusca-toffee like flavor while the berries of ‘New York Muscat’ have muscat flavor.
