i dont think they are talking about the rights to name or anything... i think they mean things like do you know if it is prone to hermie? is it stable or does it have some undesirable genetics that creep up every so many, or any number of reasons that its genes dont deserve to be propagated and spread. it actually hurts the industry and the art.
its like you CAN breed your mean ugly sickly dog to a wolf... but why would you? you know nothing about your plants genes, its tendencies to get disease or mold, its chance of foxtailing or any number of things... so why breed it? grow it a few times, see if it is even something you want to breed.
big is the only adjective you use to describe the male... is it good smoke? are its genes worth passing along? is there a trait in that strain you are wanting to pass to the other strain?
getting seeds so you dont have to buy them is a good thing, but you might want to do a bit more investigating to get a good strain worth your effort.
