Try Dip pollen on some blooms and tet pollen on some blooms, if you get seeds from one or the other you will know what you have then, and if it is fertile or not. Going the other way try some pollen on dips and some on tets.

Pollinate in the morning before it gets too hot.

So a Dip has to be pollinated with Dip pollen for a seed pod to form and same for Tet's?

Not all daylilies are fertile. Some are pollen fertile only, and others are pod fertile only. Some are just plain not fertile either way. You just have to find out by trial and error, if you do not know the name of the cultivar.

Hi Sharon,
First, take pollen from the unknown plant (X), and pollinate the same flower. Self pollination. Mark the flower and several days later, if a pod forms, the plant is probably both pod and pollen fertile.
If you have other plants that you know are diploid and tetraploid, take pollen from plant X and pollinate several of the dips and tets. Be sure to mark the flowers. Then as this plant X blooms, each day pollinate flowers with dip pollen and tet pollen. Tets are as a rule, not as fertile as dips, so pollinate around 3 tets for every 1 dip. After you have done at least 4 tets, observe any pods that form.
Both dips and tets will usually set pods on each other initially, but after 2 or 3 weeks, the pod will dry up and fall off. Occasionally the pod will ripen but when you open it, the seeds are soft and squish easily. These are non-viable seeds and in this case mean that the plant was pollinated with pollen of the wrong ploidy.
It is best to do the pollination early in the morning, as soon as the pollen turns fluffy. You should try several pollinations because not every pollination will result in a pod, even when the ploidy is the same for both flowers. After 5-6 weeks, pods with hard, black, shiny seeds will indicate the correct ploidy of plant X.
Okay?

Thanks guys, I think I have it. Of course, now I will have to wait till next year to try it out. I have a few reblooms right now , but not enough to try this with.
