The pair used the same two varieties to create the white wine grape Seyval blanc, making the two siblings rather than color mutations of one or the other.
[1] Seyval noir was created by French grape breeders Bertille Seyve and Victor Villard at their Saint-Vallier vineyard and nursery in the Isère department of eastern France.
This parentage makes Seyval noir a complex hybrid, meaning that within its pedigree are genes from several Vitis species.
[2][3] Seyval noir is moderately winter-hardy vine which is able to survive the cold winters and late springs of Quebec.
[1] As a relatively recently created hybrid, Seyval noir does not have many synonyms with only the breeding code Seyve-Villard 5247 generally recognized.
