I am looking for introduced tetraploids that have been successfully self-pollinated (the seedlings from the self-pollinations raised to flowering). Any one know of any?

Maurice, I'm not sure I understood well, but I was just looking at this:
Daylily (Hemerocallis 'Bonibrae Stairway to Heaven')

Is it something like this you were looking for?

@cybersix Yes, it is. Thank you. Sadly I think it is too new and therefore it is too expensive to use for my experimental tests.

I would say so, $150 for a single fan!

Maurice, Rich Howard does some self crosses. I don't know if he has grown any out and would have seedlings you might be able to use. Could be worth a try to ask him.

@char Thank you. I have sent off an email.

You're welcome!

I won an auction from him for seeds a few years ago. It was Dragonfly Dawn x Dragonfly Dawn. Out of the 4 seeds that germinated and grew, only one seedling still exists and it is struggling. The others perished after 2 -3 years. Not sure why. I just know they were not strong plants. Or at least could not handle the conditions in my climate and garden. I often wondered if there was something in the genetics of a self-cross of that cultivar that made it "weaker".

Good luck, Maurice! I am sure he will have some to possibly sell to you.

I have 3 pods on Forbidden Fantasy that are X Forbidden Fantasy. I ran out of other blooms to cross them with so I said what the heck. I also have 1 pod on Forestlake Ragamuffin that is X Forestlake Ragamuffin same thing happened. I will grow them out just to see what they look like but I don't have any that are already growing that are self-pollinated

That's interesting since I can't get BONIBRAE MISS DIRECTION to set for the life of me.

Next time try it x's it's self

I did not that long ago. I'll have to see if it stuck!

Hybridizer's description for Bonibrae Miss Direction

"This complex-eyed burgundy-red narrow form can have anywhere from one arrow up to 3 on most days. These flowers which have a nice white-gold edge above a large green throat beg to be noticed! pollen fertile, pods are possible in the right conditions."

....same idea as 'inbreeding' in pets or humans that marry and have kids with people that are too closely related to them...the lack of diversity of genetics means that a negative recessive trait has a higher likelihood of ending up in both alleles if the two parents are closely related.

I do have a few pollinations this year that are self-pollinated flowers. I also have a few where I pollinated them with something else, but made a note that there was already its own pollen on the stigma and self-pollination, though accidental, may have occurred. It'll be interesting to see what becomes of those. One of my intentional self-crosses was a diploid, but I think I also did 2-3 tetraploid self-crosses, too.

DND - You know, I may have spoke prematurely about DD x DD. I don't actually have Dragonfly Dawn (the parent). It could be that it is one of those cultivars that just does not do well in my climate, which could explain why the children didn't do well either. The blooms were beautiful and I did make some crosses using them as parents. And I also have some crosses of the children with each other. But I thought the same thing as you about inbreeding. I was told by someone here on the forum that that is not an issue with tets.

Now I also need someone to clarify for me about dips. I thought they wouldn't produce seeds if self-pollinated? And I know it is very, very rare for seeds to be produced from a tet x dip (nearly impossible), correct?

One would think that after a century most cultivars are inbreed and similar genetically.

Becky, there are dips that will produce seeds from self-pollination, Hemerocallis lilioasphodelus (syn. flava) and 'Stella de Oro' come to mind.

Sue - Do most of the more current dips produce seeds if self-pollinated?

I don't think so but that's a question for Maurice @admmad

beckygardener said:Do most of the more current dips produce seeds if self-pollinated?

The answer is not known but I expect that most current diploids will not produce seeds if self-pollinated.
