Grapevine plant named ‘GENSEL 2’

Abstract

‘GENSEL 2’ is a new and distinct grapevine plant with novel characteristics that include good fertility and naturally loose bunches, nice and well-structured. The berries produced by ‘GENSEL 2’ are red and seedless with a very crisp texture and neutral flavor and no detectable seed traces. The berries produced by ‘GENSEL 2’ are very large, weighing 11-12 g/berry on average, and harvested in early September in Murcia Region (Spain).

Description

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

Cultivar denomination: ‘GENSEL 2’.

BACKGROUND OF THE INVENTION

The present invention relates to a new distinct variety of seedless grapevine named ‘GENSEL 2’. The new variety originated from a hybridization performed in Murcia, Spain during 2015 between ‘05-611-169’ (U.S. Plant Pat. No. 33,449), 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 2’ was performed during 2017. ‘GENSEL 2’ 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 2’ 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 2’. ‘GENSEL 2’ produces very large, red (5 R3/4), seedless berries with a very crisp texture that are harvested in early September, in Murcia-Spain and weight on average 11-12 g/berry.

‘GENSEL 2’ is believed to be most similar to ‘Sheegene 3’ (U.S. Plant Pat. No. 21,316 P3) but differs in maturity. Specifically, ‘GENSEL 2’ matures in early September whereas ‘Sheegene 3’ matures in early August. The berries produced by ‘GENSEL 2’ have a globose shape while the berries produced by ‘Sheegene 3’ have an ovate shape. ‘GENSEL 2’ produces berries with a very firm texture with resistance to cracking whilst the ‘Sheegene 3’ berries are firm and less resistant to cracking. The new variety, ‘GENSEL 2’, has a lower fertility rate than ‘Sheegene 3’ (1.1 v. 1.3).

‘GENSEL 2’ can be distinguished from its male parent, ‘05-611-169’, in that the new cultivar produces red-coloured (5R3/4) grapes while ‘05-611-169’ produces white grapes. ‘GENSEL 2’ clusters are less heavy than ‘05-611-169’ clusters (average 600 g v. 750 g). The bunches of ‘GENSEL 2’ are loose whilst the bunches of ‘05-611-169’ have a medium compactness. The berries of ‘GENSEL 2’ have globose shape while the berries of ‘05-611-169’ are obovoid.

‘GENSEL 2’ can be distinguished from its female parent, ‘9-704’, in that the berries of ‘GENSEL 2’ have a globose shape whereas the berries of ‘9-704’ have an oval shape. The bunches of ‘GENSEL 2’ are loose whilst the bunches of ‘9-704’ have a medium compactness. The harvest time of ‘GENSEL 2’ is in early September whilst the harvest time of ‘9-704’ is in early October. The new variety, ‘GENSEL 2’, has a lower fertility rate than ‘9-704’ (1.1 v. 1.4).
