Green indicates countries where the variety is listed in the national catalogue and its seeds are authorized for sale. Expired registrations are marked separately: the variety was previously admitted, but sale is no longer permitted.
A single variety may be registered in different countries under different names. All records are consolidated into one profile based on the breeder's code—an internal number that is identical for the variety across all registries.
The primary name shown is the one under which the variety is registered in the largest number of jurisdictions. Search finds the variety by any of its names.
The right is granted for a limited term: propagation of the variety requires a license from the rights holder.
