@SunriseSide Two of the triploid seedlings were registered with the AHS.

VT Spirit (Pinkham-Li-Conev, 2010)

Most of the triploid seedlings were discarded. I managed to get two (or it might have been three) and those were the only ones still being grown. They might have included the two that were registered (I would need to check my field maps for their names).
No other research on triploid daylilies has been published by the research group and as far as I know the daylily hybridizer who was involved with the research has not produced or registered any other triploid daylilies.
