 Marechal Foch (Kuhlmann 188-2), De Chaunac (Seibel 9549), Baco noir, and Leon Millot are some of the successful hybrids introduced by de Chaunac.While vitis vinifera varieties have ultimately supplanted the majority of French hybrid plantings in eastern North America, hundreds of hectares remain in production, some even used to produce "cult wines" from old vine plantings.The De Chaunac (Seibel 9549) grape variety, still grown in some northeastern wine regions, was named after Adhemar de Chaunac.
