Out of all the poly daylilys you have bred with, which one has been the best at throwing polys in a F1 cross to a non poly lily?
I realize that in general you need to cross poly to poly to get poly offspring, but curious if any success has been had in a outcrossing.
Also, out of your breeders which polys when crossed with other polys produce the most poly offspring?

I am not a poly breeder, however you can get some information about your questions by using the American Hemerocallis Society website pages for daylily registrations - http://daylilydatabase.org/ if you click on the Advanced Search - http://daylilydatabase.org/?ad...
Part way down the screen page there is a check box for the Flower Form - polymerous. By checking that box and clicking on the search button (or press the enter key after checking the box) a list of all daylilies registered as polymerous will be shown.

You would need to do your own tabulations and comparisons (from the parentage information - for those records where it is present) and the information in the database is not a random sample but it is a start.
