I found this rule about using a prefix or suffix: From the AHS naming rules
"11. The names of cultivars that have won the AHS Stout Medal may not be used with any prefix or suffix
to create a new name subsequent to the cultivar having won the award."
Edited to add: There are other rules that might apply in different cases: So here are the rules.
