Abstract

‘GENSEL 3’ is a new and distinct grapevine plant with novel characteristics that include good fertility and excellent fruity labrusca flavor. The berries produced by ‘GENSEL 3’ are reddish black and seedless with a crisp texture and no detectable seed traces. The berries produced by ‘GENSEL 3’ are large, weighing 9 g/berry on average, and harvested at the beginning of August until the end of September in Murcia Region (Spain).

Description

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

Cultivar denomination: ‘GENSEL 3’.

BACKGROUND OF THE INVENTION

The present invention relates to a new distinct variety of seedless grapevine named ‘GENSEL 3’. The new variety originated from a hybridization performed in Murcia, Spain during 2015 between ‘550P-2010’ (not patented), as the pollen parent, and ‘9-704’ (U.S. Plant Pat. No. 23,125), as the seed parent. Abortive seed traces were embryo cultured and the resulting plant was planted in an evaluation block during 2016. The first evaluation of the fruit produced by ‘GENSEL 3’ was performed during 2017. ‘GENSEL 3’ was first asexually propagated by field grafting dormant hardwood scions to 1103 Paulsen Rootstock (not patented) in 2018 in Murcia, Spain. Fruit from the resulting four grafted ‘GENSEL 3’ vines was first harvested in 2019. All characteristics and distinctions remain true to form and are established and transmitted through succeeding propagations.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishing characteristics of ‘GENSEL 3’. ‘GENSEL 3’ produces naturally large (9 g/berry) seedless reddish black (5 RP3/2) berries having a broad ellipsoid shape with an excellent fruity labrusca flavor, that are harvested from mid-August to mid-September, in Murcia-Spain.

‘GENSEL 3’ is believed to be most similar to ‘Kyoho’ (unpatented). Nonetheless, the new cultivar can be distinguished from ‘Kyoho’ based at least upon harvest period, seedlessness, berry texture and cluster compactness. ‘GENSEL 3’ matures from mid-August to mid-September whereas ‘Kyoho’ matures in August. The berries produced by ‘GENSEL 3’ are seedless whilst the berries produced by ‘Kyoho’ have seeds. ‘GENSEL 3’ produces berries with a very firm texture whilst the ‘Kyoho’ berries are soft. The new variety, ‘GENSEL 3’, has tight bunches whereas the bunches of ‘Kyoho’ have a loose compactness.

‘GENSEL 3’ can be distinguished from its male parent, ‘550P-2010’, in that the new cultivar is harvested from mid-August to mid-September whilst the harvest time of ‘550P-2010’ is in end of July. ‘GENSEL 3’ clusters are heavier than ‘550P-2010’ clusters (average 550 g v. 300 g). The berries of ‘GENSEL 3’ are larger than the berries of ‘550P-2010’ (average 23.4 mm v. 15 mm). The berries of ‘GENSEL 3’ have a very firm texture whereas the berries of ‘550P-2010’ are soft.

‘GENSEL 3’ can be distinguished from its female parent, ‘9-704’, in that the berries of ‘GENSEL 3’ have a broad ellipsoid shape whereas the berries of ‘9-704’ have an oval shape. The berries of ‘GENSEL 3’ have an excellent fruity labrusca flavor while the berries of ‘9-704’ have a neutral flavor. The bunches of ‘GENSEL 3’ are tight whilst the bunches of ‘9-704’ have a medium compactness. The harvest time of ‘GENSEL 3’ is from mid-August to mid-September whilst the harvest time of ‘9-704’ is in early October. The new variety, ‘GENSEL 3’, has a lower fertility rate than ‘9-704’ (1.2 v. 1.4).
