When I started messing with pollen in the early 90s I new nothing about where to locate the parentage and really never gave it a thought. I crossed what I JUST KNEW was going to produce pretty flowers, had a lot of barkers in those days and to be honest not much has changed today. I am more concerned about the flower being pretty and having some dormancy when I buy one to use. I pay more attention to my dip crosses than the tets. What few flowers I bought to hybridize with this year are dips from the north. I will do more dips this year than I normally do, I have better sucess with the dip UFs.
With the progress made in dips the last few years it would be almost impossible to tell them from the tets without checking the pollen.
