Hybrid naming convention for mutated mericlonesss

[Subrosa]

I have a plant labeled as Blc Hawaiian Passion 'Lakeview Pink Lip' mutation. I don't know the convention, but direct and to the point definitely works at imparting the required info.

[SouthPark]

Subrosa..... is Blc. Hawaiian Passion 'Lakeview Pink Lip' the original plant? And there is a mutation of it?

The definition of "cultivar" from International Code of Nomenclature for Cultivated Plants:

A cultivar, as a taxon, is an assemblage of plants that
(a) has been selected for a particular character or combination of characters, and
(b) remains distinct, uniform, and stable in these characters when propagated by appropriate means…

So, if a permanent difference in appearance** arises in an existing cultivar it no longer conforms to "a particular character or combination of characters" or to "uniform, and stable in these characters". It is no longer the same cultivar as originally defined. The former cultivar name should not be used. It should be given a new cultivar name, or revert to using only the grex name as for a seedling.

Of course, it is not inappropriate to describe it as coming from 'Example Cultivar Name' but it is not 'Example Cultivar Name'. The new name could include the former name as in 'Example Cultivar Name Splash', or any other acceptable cultivar name could be given. It is not appropriate to use "var." to describe any plant known only in cultivation or that hasn't been formally described and published.

**Technically, it shouldn't be called a mutation unless it is known to be inheritable.

Great post PMM. Thanks very much for that! It does clear things up a lot.

PMM ...... I don't know a great deal about how DNA works. I need to read a bit into this biology area sometime soon!

Do you happen to know if a mutated hybrid (from some arbitrary grex) is hypothetically equivalent to a natural sibling from that grex? That is --- if mericlone of 'Sweet Afton' is mutated, and the features of the mutation are stable, then could the mutated plant be considered as a member of the grex, as if it were a sibling?

The Rlc. Memoria Helen Brown 'Sweet Afton Splash' (mutated from 'Sweet Afton') became (*I think*) perloric from the mutation (which relates to the person adding the splash descriptor) - appears to have stable features.

The changed hybrid (whether truly a heritable mutant or not) is definitely a member of the grex in terms of sharing the grex name. The change(s) most likely could have happened just as easily in a seed or young seedling of the original pod, and in that way it is indistinguishable from a sibling from the original pod.

Thanks very much for sharing that knowledge PMM. This really helps a lot. A tremendous lot actually. Really appreciated.

Hi Arron! --- After processing all the information gathered so far, I'm going to temporarily tag the plant as:

Rlc. Memoria Helen Brown 'Sweet Afton m. Splash' which retains some immediate information about its origins. A departure from convention with everything placed between the single quotes - but I think I'll go with this. The m. will just mean 'mutation'.

If it turns out that the above labeling isn't satisfactory, I can always fall back to just Rlc. Memoria Helen Brown 'Sweet Afton Splash'.

I'm just going to point out that Rlc George King has two varieties that are commonly available, 'Serendipity' and 'Southern Cross', with 'Southern Cross' being a mutation that occurred in the cloning of 'Serendipity'. They have each received an Award of Merit from the AOS, and thus their names are always rendered Rlc George King 'Serendipity AM/AOS and Rlc George King 'Southern Cross' AM/AOS and are considered two distinct clones of George King with two separate names. i don't know if that helps, but there it is.

[SouthPark]

That does help JScott. It's definitely nice to know what has been done with that kind of situation. Nice to know about those options.
