well thats my point of view, the difference between a crosser and a breeder is innovation,
I agree with your premise
and by crossing 2 already established strains you dont breed something new, you just recombine
I am not so sure about your conclusion, though.
If you have ever crossed anything, even to f2 or f3, I am sure you will have been amazed by the variety that the throwbacks can generate. I have found plants that were totally different to their parents in just about
every respect, sometimes with amazing properties of their own!
We have to remember that our plain old market-bought cannabis seeds have some amazing recessive phenos in them these days, just waiting to be discovered. Once they
are discovered it's pretty damn hard work do draw these new-found traits out and stabilise them -- but probably worth it. You would need serious facilities though, as you'll have to throw out a LOT of stuff.
Not as fun as travelling round the world looking for "new" stuff, but just as valuable, perhaps even more so.
But we are a lazy lot, aren't we, and want everything super-duper ready at the press of a button. And as I already said, the illegal status doesn't help at all...
