USPP33357P2 - Seedless table grape (grapevine) named ‘Itumseventeen’ - Google Patents

Abstract

A new and distinct variety of grapevine named of ‘Itumseventeen’ is herein disclosed. ‘Itumseventeen’ abundantly forms medium sized light green to yellow colored berries with an attractive broad ellipsoid berry shape, a Muscat flavor and a firm berry texture. Being mid-season variety, the fruit commonly is ready for harvesting in from July to early September in Blanca, Murcia, Spain. ‘Itumseventeen’ displays good eating qualities as a table grape, the fruit meatiness and firmness render the fruit amenable for handling, shipping, and storage.

Description

Latin name of the genus and species: Vitis vinifera.

Variety denomination: ‘ITUMSEVENTEEN’.

BACKGROUND OF THE INVENTION

A breeding program was initiated during 2003 at a research nursery in Blanca, Murcia, Spain. During the development of this breeding program, a new variety of Vitis vinifera was created by deliberate cross breeding of two parent plants by emasculation of the pollen bearing organ of the female and introducing pollen from another male origin. The female parent of the new variety is ‘ITUM-150-242’, an unpatented proprietary selection. The male parent (i.e. the pollen parent) of the new variety is ‘Superior’, unpatented.

‘Itumseventeen’ was identified as a potentially interesting selection during 2014 at the same location in Murcia, Spain. After identifying the new variety as a potentially interesting selection, first propagation of ‘Itumseventeen’ by vegetative cuttings was undertaken during 2015, at the research nursery in Murcia, Spain. Controlled testing and propagation of the new variety continued, to assess stability of the unique characteristics of this variety. Subsequently, several generations have been reproduced and have shown that the unique features of this cultivar are stable and reproduced true to type No commercial sales occurred before the filing of the US plant patent application.

SUMMARY OF THE INVENTION

The cultivar ‘Itumseventeen’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype. The new variety ‘Itumseventeen’ is a yellow to light green seedless table grape with medium production and a high fertility index “1, 6”. In addition to the before mentioned characteristics, the following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Itumseventeen’. These characteristics in combination distinguish ‘Itumseventeen’ as a new and distinct Vitis cultivar:

• • 1. Medium sized individual fruit with yellow to light green skin coloration; formed in medium-to-large clusters.
  • 2. An attractive broad ellipsoid berry shape.
  • 3. A mid-season season variety, commonly bears fruit for harvesting from July until early September in the region of Murcia, Spain.
  • 4. Firm berry texture.
  • 5. Seedless.
  • 6. Resistance to cracking.
  • 7. Fruit has been found to be suitable for handling and shipping.
  • 8. Observed tolerance of water shortage.
  • 9. Observed tolerance for temperatures up to 41° C.
  • 10. Muscat flavor profile.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographic illustrations show typical samples of vegetative growth of a 5 year old specimen of the new variety, in color as nearly true as it is reasonably possible to make in a color illustration of this character. Plants were grown in Murcia, Spain. Colors in the photograph may differ from the color values cited in the detailed botanical description below, which accurately describes the colors of the new Grapevine.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart 2015 except where general terms of ordinary dictionary significance are used. Some descriptors, when useful have been incorporated from UPOV Grape Descriptor Guidelines. The description is based on the observation of plants growing on ‘1103 Paulsen’ (not patented) rootstock in clay stony soil conditions in the fields near Blanca, Murcia, Spain. The age of plant described is of 5 years, with an average height of 200 cm, a high canopy density, a 300 cm plant spread, a one-year growth rate to reach two meters high and 20 to 30 days to initiate roots at approx. 20° C. At observation location temperature ranged between 15° C. to 35° C. during the day, and between 5° C. to 20° C. during the night.
