Grapevine plant named ‘14-37-111’

Abstract

This new variety ‘14-37-111’ is new and different because of its unusual shape, early ripening, very firm texture and very large berry size. It differs from other early ripening red grapes such as ‘Flame Seedless’ (not patented) in having an ovate berry shape and much larger berry. It differs from other later ripening red, seedless grapes such as ‘Crimson Seedless’ (not patented) due to its greater fruitfulness and much larger berry size following applications of exogenous gibberellic acid and trunk girdling.

Description

Genus and species: Vitis vinifera.

BACKGROUND AND SUMMARY OF THE INVENTION

The new table grapevine ‘14-37-111’ is of Vitis vinifera parentage and resulted from a twenty year breeding program which had as its goal the development of an early-ripening, brightly colored, red, seedless table grape. The female, seed parent was an unnamed and unpatented plant resulting from a series of crosses involving ‘Hunisa’, ‘Flame Seedless’, ‘Emperor’, and ‘Thompson Seedless’. The male parent of the cross is an unnamed and unpatented, seedless grapevine resulting from a series of crosses involving ‘Emperor’, ‘Thompson Seedless’, ‘Muscat of Alexandria’, and ‘Calmeria’. The hybridization resulting in ‘14-37-111’ was made in 1993 near McFarland, Calif. The seedling was selected from a population of 47 seedlings of like parentage in 1996. It was then propagated by cuttings and grafting to variety ‘Freedom’ rootstock. This new variety has been found to retain its distinctive characteristics through successive propagations; and this novelty is firmly fixed.

The new grapevine variety, cultivar ‘14-37-111’ is similar to the seeded cultivar ‘Emperor’, from which it descends, but differs from it by being seedless, with traces that are not noticeable due to their small size and the crisp flesh of the berry. ‘14-37-111’s ripening period is much earlier in the year, ripening approximately 1 week later than cultivar ‘Flame Seedless’ (unpatented) at Delano, Calif. The present variety differs from ‘Flame Seedless’ by having an ovate berry shape and a having a much brighter red berry color and ripening about one week later than ‘Flame Seedless’. It differs from the cultivar ‘Crimson Seedless’ by having a much greater fruitfulness, yielding one or two clusters from spur-pruned vines, being less vigorous in its growth habit, and ripening about three weeks earlier at Delano, Calif.

DETAILED BOTANICAL DESCRIPTION OF THE INVENTION

The following description of grapevine ‘14-37-111’ contains references to color names taken from The Munsell Color Chart for Plant Tissues, published by Munsell Color, New Windsor, New York. Descriptors used herein conform to those set forth by the International Board for Plant Genetic Resources Institute Grape Descriptors (Vitis spp.) of 1983 and/or 1997 which were developed in collaboration with the Office Interantional de la Vigne et du Sin (OIV) and the International Union for the Protection of New Varieties of Plants (UPOV).

Descriptions of the new invention apply to vines of ‘4-37-111’ grown on ‘Freedom’ rootstock at a density of 1,537 vines per hectare grown in Kern County, Calif. in 2001. These vines were in their first year of full production having been planted in 1998. These descriptions are believed to apply generally to the new variety grown under similar circumstances elsewhere:
