Re: Re: breeding 6 fall irises

   I know exactly what you're talking about. F2 x F1 in my birds has produced
amazing results. I can see the striking similarities with irises and going
back to the flat pod parent just as I have gone back to the maternal fowl line
with the F2s.

   So it would be something like this...

Six Pack x Batik = F1
Six Pack x F1 = F2

F2 x F1
... With each filial cross involving multiple
crosses between its members.

Thanks!
