My explanation of the process is the way I understand it in the simplest of terms, however, may not be completely representative. That would be an excellent question for Beth Lamb, she also does a lot of work for ag companies getting viruses out of commercial crops and is in FL. If you google her, I think you could find contact info. I know Dave Off has her info as both he, Art Chadwick and Keith Davis have sent her historic plants. Keith is the most scientific of the 3 having been on UNC's hort staff, and would be happy to talk to you. He does not sell plants, but has a website with contact info and would not mind the contact at all. https://keithdavisorchids.com/index-orchids.htmDoesn't the invitro process of many repeated cloning phases for virus removal have high risk of genetic mutation?
If so then there becomes a risk that the cleaned clone may not actually be a division of the original prized plant. Mutated clones can look identical but actually pass on different genetics when used it producing new hybrids.
