That is an excellent question
@TomThumb -- please let me know if you find anything out.
I haven’t done an in-depth search, but I’ve casually looked on the internet for answers to daylily hybridizing questions like that. Bits of good info here and there but a bit surprising that I have not found more...
I wonder if that’s because there really isn’t a whole lot that can be said with any high level of certainty. The genetics of tetraploid daylilies is so complex that it produces a very wide range of results making it difficult to determine patterns or rules.
I recently found another possible reason why it can be difficult to see patterns or rules.
I like to use photo editing software to overlay photos of daylily blooms. I don’t expect that to be a highly accurate predictor of what seedlings will look like, but on the other hand it is certainly possible that some of the seedlings of some crosses will be a blending of the blooms of the parents—and this gives me an idea of what that would look like.
I tried that with a bloom that has fairly prominent red veining. When overlaid on a gold-colored bloom the veining remained quite visible, but when overlaid on a beige bloom the veining almost disappeared!
You can imagine what one would think if this actually occurred in real life. Even if veining was highly dominant and was actually present on almost all the seedlings, you wouldn’t see it on many seedlings that had the right color to mask it...
