"However, since the rose is not registered as 'Alberta Bouquet' the RR1 name should be primary." (Pittao).

This comment by Mr. Pittao is absolute nonsense. Many roses developed by breeders initially had numbers to identify them, then named but not registered. The whole point in giving RR1 a name was to recognize its good quality and make it better known. Who wants a rose identified as RR1?
