Yep I was aware of the meaning behind the generations and I think Rachel once posted that she considers them the same way you listed it. My question was more to the point of does it really matter what F# they are? Is there an expectation of breeding results, hardiness, loss of quality as the generations continue? I know through selective breeding traits can be defined and eventually breed true in successive generations, but does it really matter in general terms? Or are we just looking at the possibility of unique characteristics which possibly can be bred into a new line and understanding the lineage it took to get there?
