Australis said:I, too, am interested in this discussion and would like to know if such interdivisional crosses are easier at the 4N level. I am not aware of any tetraploid OA hybrids....
Nor am I, but then I'm barely aware of OA hybrids existing given they aren't common. Its why I used it as the example, given how different they are with germination seems like a good example to see if anyone knows if the germination at tetraploid level is possible at the 4N.
Largely just curious given other polyploid crossings in other plants becoming more viable to achieve fertility and germination in their wider crosses...just seems odd that it hasn't been explored with liliums, someone surely knows something.
