If it is a true unknown then they would either have to check the pollen or pollinate it with the tet and dip pollen and see which one sets. A lot of times when a daylily is listed with unknown parents it's not really an unknown as far as ploidy. It could have been a seedling that got the tag lost and they are unsure of the cross or a seed pod they forgot to mark when harvesting or tags got mixed up with another close by. I only work with tets so if I had an unknown parentage then I know it's a tet. My friend only does dips so any of her unknowns would be dips. And we keep them in separate beds so there is no way of getting them mixed up and the seedlings are separate as well.
