'Blanc du Bois' has been recognized as a premium wine grape cultivar in Florida. However, it is highly susceptible to the fungal disease anthracnose. Although it is tolerant to Pierce's disease (PD), symptoms ranging from mild to severe were found under certain circumstances, particularly under stress conditions. Extensive care and a carefully managed fungicide spray program are necessary to ensure a good crop. To test the feasibility of using muscadine as a rootstock for cv. Blanc du Bois, we successfully grafted 'Blanc du Bois' on to muscadine by using a chip budding technique. Grafted and non-grafted 'Blanc du Bois' wines were evaluated for 3 years. Muscadine rootstock had no significant effects on berry size and total acid, while soluble solid content was slightly higher in the grafted vines. Muscadine rootstock limited the development of PD and anthracnose. The preliminary results demonstrated that muscadine rootstock could be beneficial to the production of 'Blanc du Bois' although technical difficulty of using muscadine as rootstocks has to be overcome.
