ZenMan, I read this entire thread and am astounded by your knowledge. I just this minute joined this forum. I had been googling about how to breed zinnias and landed here. I am considering buying commercially grown seed of the color and flower type that I like and cull hard for the next generation seed. I would like to do this for several generations, and just look for improvements and the occasional mutant. May try my hand at cross breeding later on down the road. I live in zone 9 so can squeeze out two outside-grown generations a year easily. Thanks for sharing your Zin Wisdom.
