Reliable data on origin, parental forms, maturity group, disease resistance, and detailed product quality characteristics are absent in open sources.

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.
