Latin name of the genus and species: Vitis vinifera.
Variety denomination: ‘ITUMNINE’.
BACKGROUND OF THE INVENTION
A breeding program was initiated during 2003 at a research nursery 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 a different male variety. The female parent of the new variety is ‘Autumn Royal’, U.S. Plant Pat. No. 2,906. The male parent (i.e. the pollen parent) of the new variety is ‘Princess’, unpatented.
‘Itumnine’ was identified as a potentially interesting selection during 2008 at the same location in Murcia, Spain. After identifying the new variety as a potentially interesting selection, first propagation of ‘ITUMNINE’ by vegetative cuttings was undertaken during 2009, at the research nursery in Murcia, Spain. Controlled testing and propagation of this 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 publications have been issued on the plant breeding invention. Date of first sale was Aug. 27, 2019, occurring in Europe. This sale was made directly by the inventor or one who obtained the claimed invention directly or indirectly from the inventor. This sale and all public disclosures made between Aug. 27, 2019 and the fifing of this application fall within the exception allowed under 102(b)(1).
SUMMARY OF THE INVENTION
The cultivar ‘ITUMNINE’ 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 ‘Itumnine’ is dark red-violet seedless table grape with medium production and a medium fertility index “1, 1”. In addition to the before mentioned characteristics, the following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Itumnine’. These characteristics in combination distinguish ‘Itumnine’ as a new and distinct Vitis cultivar:
-
- 1. Unique dark red-violet skin coloration.
- 2. Medium to large clusters.
- 3. A late season variety, commonly bears fruit for harvesting from September to October in the region of Murcia, Spain.
- 4. Moderately firm berry texture, crunchy to bite on.
- 5. Absence of seeds.
- 6. Cylindrical berry shape
- 7. interesting flavor: neutral with a semi-acid twist.
- 8. Fruit has been found to be suitable for handling and shipping.
- 9. Observed tolerance of water shortage.
- 10. Observed tolerance for temperatures up to 41° C.
- 11. Neutral flavor profile.
- 12. Resistance to cracking.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying photographic illustrations show typical samples of vegetative growth of 10 year old specimens 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.
FIG. 1 illustrates a fruit cluster of ‘Itumnine’.
FIG. 2 shows a close up view of the trunk of ‘Itumnine’.
FIG. 3 illustrates in close up perspective typical foliage of the new variety, both front and back of the leaf.
FIG. 4 illustrates the plant canopy of ‘Itumnine’, including fruits, branches and foliage.
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 teen incorporated from UPOV Grape Descriptor Guidelines. The description is based on the observation of plants growing on ‘1103 Paulsen’ (unpatented) rootstock in clay stony soil conditions in the fields near Blanca, Murcia, Spain. The age of plant described is of 10 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.
