Interpretive Summary: Concord grapes have a unique, desirable flavor but they are seeded and have soft flesh with slip skin texture which is undesirable for the consumer. Thompson Seedless was hybridized with Concord to produce Thomcord, a blue-black, seedless grape with the desired Concord flavor. Thomcord is suitable for production in the hot, dry growing conditions of the San Joaquin Valley and its fruit has been accepted in farmers markets as well by commercial retailers.

Technical Abstract: Thomcord (Vitis vinifera L. x V. labrusca L.) is a midseason, blue-black seedless table grape that is suitable for farmer’s markets and shipping to domestic markets. It has the aromatic flavor reminiscent of Concord with firmer flesh and skin that adheres to the flesh. It is more suitable to the hot, dry growing conditions found in the San Joaquin Valley than Concord.
