From Prim and Proper X Tetraploid Aril. An interesting set of experiments resulted from an upended tray of tetraploid aril pollen. I never have enough for all of the crosses I want to make, so when the contents of several cups were mixed I just used it up on 1/4-breds and 3/4-breds to test compatibility. So I don't know the pollen parent, but I do know that it was a tetraploid aril. This one will not be registered, but the knowledge obtained from this cross proved extremely valuable.
