The designation 234 B represents breeding material, not a variety or hybrid for commercial cultivation. The line is used in pairs with a corresponding sterile line to create sunflower hybrids.
This material is used in scientific research related to oilseed breeding, including work on evaluating combining ability and studying heat tolerance and genetic purity.
2 jurisdictions
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.
Records are sourced from official registry publications. Data sources and legal status
The directory replicates the primary source. If an entry differs from the official publication, please specify the discrepancy and provide a link if possible. Corrections are added to the moderation queue.
