If a breeder truly wanted to stabilize a strain they could pop a few hundred s1s and select a mother as close to the original as possible and than back cross. Those back crosses would be great stock but nothing wilm be as close to original mom than an S1 or F1 cross.
The reason breeders back cross is trying to get close to a mom when they only had F1 seeds to work with from the beginning and a Male used that wasnt close to the target strain.
F1S and S1s are always gonna be the best crosses IMO because trying to select generations only gets further away unless the breeder is looking for something different.
That is wrong thinking. Look at gg4 s1. Full of chemsis and dub leaners. Very few gg4 s1 resemble the cut. You have to get lucky or run through massive numbers. When you backcross or self, plants get less heterozygous each generation. This leads to trait segregation particulary in the trendy poly hybrids of today.
Pop a bunch of gg4 s1 versus my gorilla bubble bx4. You will find a much higher frequency of gg4 leaners in the bx4. In gg4 s1 you see mainly segregation of the glue traits and that leads to all those phenos that look like gg4 ancestors. Chemsis the dub etc.
Selfing only gets you a high frequency of plants that look like the mom if she was mostly homozygous to begin with. With a poly hybrid s1 will not deliver a high frequency that resemble the mom exactly at all.
Further generations only get further from the original mom with poor selection. A skill that is not relied on largely by todays "chuckers".
