Also, if a plant had tried to be converted and was not successful you can run into confusion there because sometimes the plant will have half dip and half tet pollen. These plants are used and pods are set before it completely reverts back to full dip. I have some seedlings that the pod parent is a tet and was planted in the wrong bed with the dips. Well, dip pollen kept being put on it and I have seedlings from this cross. I do know that the plant had tried to be converted and was not succesful and so I must have ended up with one that had some of both pollens still.
I wish I would have realized it at the time and I would have definitely kept that fan when I divided the plant, but I really have no idea which fan it came from.
