Seedless table grapevine named ‘Itumtwelve’

A new distinct variety of Vitis vinifera (Table grape) named ‘Itumtwelve’ forms distinctive seedless fruit with a black berry skin and a narrow ellipsoid berry shape. Fruit has a neutral flavor and a very firm flesh that together with a medium thickness of skin makes it crunchy at the first bite. Being a mid-season variety, the fruit commonly is ready for harvesting from August to mid-October in Murcia, Spain, and displays good eating qualities as a table grape. The fruit meatiness and firmness renders the fruit amenable for handling, shipping, and storage.
