Abstract
A new and distinct variety of diploid grapevine is provided which abundantly forms late-ripening large bunches of sweet firm crisp substantially elliptic-to-obovate large berries which develop a green to yellow-golden coloration at maturity and provide the capability for long-term storage. The plant is particularly well suited for the production of table grapes. The fruit also can be used as a dried vine fruit or for the making of wine.
