This new section has been started to help educate the public. There is alot of information that needs to go here, but this is a start.
Group = merely means a bunch of plants that sort of look similar to each other.
Strains or Seed Strains = Plants that are propagated from seed that carry some implications of genetic relatedness. They are not genetically identical,
neither to each other nor to either of their parents. Over many, many
generations of inbreeding and back-breeding, plants of a strain can become
more and more similar to each other. Still they are probably never going
to become identical in all respects.
Clones = Plants that were all propagated vegetatively from one single original mother plant. All members of a clone are genetically identical (save for any occasional somatic mutations).
An important NOTE from the President of NACS:
As far as I'm concerned, it is very important that we maintain the
distinctions between clones, seed-propagated strains, and the new
"Groups." We do no service to the public and we undercut each other's
breeding efforts when we muddy the waters between these three concepts. If
someone sells seeds labelled 'Vico Yellow' you know that -- at best! --
they are selling seeds that are actually ['Vico Yellow' X
unknown]. Everyone in the broad Clivia community needs to understand that
neither ['Vico Yellow' X unknown] nor ['Vico Yellow' X self] will produce
plants that are genetically identical to 'Vico Yellow'. To offer plants or
seeds claiming otherwise is not accurate.
