Seedless table grape (grapevine) named ‘Itumseven’

-

A new and distinct variety of grapevine named ‘Itumseven’ as herein disclosed. ‘Itumseven’ forms medium sized bright medium red colored berries with an attractive narrow ellipsoid berry shape, a neutral flavor and a firm berry texture. Being mid-season variety, the fruit commonly is ready for harvesting in from August to late September in Murcia, Spain. ‘Itumseven’ 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: ‘ITUMSEVEN’.

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 an unpatented proprietary selection referred to as ‘ITUM 97-27-31’. The male parent of the new variety is ‘Princess’, unpatented.

‘Itumseven’ was identified as a potentially interesting selection during 2005 at the same location in Murcia, Spain. After identifying the new variety as a potentially interesting selection, first propagation of ‘Itumseven’ by vegetative cuttings was undertaken during 2006, at the same research nursery in Murcia, Spain. Controlled testing and propagation of the new variety continued over several years 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. The first commercial sale of this new cultivar occurred Jan. 12, 2022. Plant material for this sale was obtained directly or indirectly from the inventor and occurred less than 1 year before filing of the US plant patent application. This disclosure meets the requirement for exception under 35 USC 102(b).

SUMMARY OF THE INVENTION

The cultivar ‘Itumseven’ 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 ‘Itumseven’ is bright medium red table grape with medium production with an average fertility index of 0.8. The forgoing and other distinguishing characteristics come true to form and are established and transmitted through succeeding propagations. These characteristics in combination distinguish ‘Itumseven’ as a new and distinct Vitis cultivar:

    • 1. Medium sized, individual berries with bright medium red skin coloration formed in large clusters.
    • 2. Attractive narrow ellipsoid berry shape.
    • 3. Typically bears fruit for harvesting from August until late September in the region of Murcia, Spain.
    • 4. Firm and crunchy berry texture.
    • 5. Seedless fruit.
    • 6. Fruit has been found to be suitable for handling and shipping.
    • 7. Observed tolerance for drought.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographic illustrations show typical samples of vegetative growth and fruit on 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 12 years old, 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.
