Hey stinky... What do you consider a TRUE F1. I have been think about it alot and its kind of hard to put my finger on what is true F1. I mean if you cross to plants that are of the same family, IBL, then the plant is homozygous right? Its when you take that IBL and cross it with another plant that is different family that the offspring will be heterozygous. (is this correct?) Thus making it a F1 hybrid. So if you take a F1 and cross it with another F1 hybrid, do you get another F1. i.e: somaG13 x 4way = ? Is this a F1 hybrid that would be recognized like this. somaG13/4way? or would it be a F2 since the strains were both F1s and already heterozygous? I thought that to be a true F1 hybrid that you would have to cross two IBLs, or homozygous strains. And can a F1 that is now heterozygous ever be inbred enough to be considered a homozygous IBL again? I was told by some one that NL was a F1 but has since been inbred so many times that it is a stable breeding strain. Am I even on the right track here, or am i way off. thanks!
