Will the young plants of any particular cultivar be that particular cultivar if the parent plant is self pollinated ? Has anyone here tried this ? What were the results ?
No, not necessarily. While under the cultivar definition of matching appearance, some
might be able to be included as a cultivar, but most would display a variety of traits that would not match the cultivar description.
Since, I believe, that common practice prior to registering a cultivar is to propagate it (presumably by vegetative methods, or else it wouldn't make any sense) and distribute some to various growers in various locations to see if the exceptional traits continue under other conditions, so having a non-vegetative-ly propagated cultivar would render this practice unnecessary; since whatever trait the original grower thought was exceptional could be based on something that is conditional and that could be reproduced by another plant elsewhere. I suppose (and this might be a reach) but if this practice of non-vegetative-ly reproduced cultivars is common practice and continues, couldn't someone just describe a plant that doesn't really exist and then seek it out later?
Personally, I think the whole cultivar issue (especially with regard to
Dionaea) is ludicrous. In my opinion, no plant should bear the cultivar name and status unless it is a direct vegetative propagation from the originally described plant. With
Dionaea cultivars that are described mostly (if not all) on exceptionally large trap size one can see how problematic the lackluster description can be when trap size is so variable to begin with.
That is exactly why I never got into the whole
Dionaea 'B-52',
Dionaea 'Big Mouth', and
Dionaea 'Big Mama Jama', etc. etc. (ad nauseum) collection debacle. There really no legitimate way to prove any of the (sized based)
Dionaea cultivars, outside of a few notable, well described exceptions or you got a vegetative-ly reproduced plant from the cultivar describer.
The only clone I can think of that's the exception is Dionaea 'Red Burgundy'.
The only other described description I can think of is
Sarracenia 'Hurricane Creek White'. Any plant from this population or reproduced from
Sarracenia leucophylla from the population
and display the characteristics is considered to be a cultivar of that name; specifically stated:
In order to maintain this cultivar’s unique hardiness, color, and size characters, do not attach the cultivar name to any seedlings that do not show the large white pitchers of this Sarracenia leucophylla cultivar.
xvart.
edit: I recall having a few rants about
Dionaea cultivars in the past, so I went back to search for them and found a couple good threads surrounding this topic:
Where in the bog is the "B-52"
