If i cs ww (partial) and use polens on other plant, would this be a x-breeding?
yes(unless the other plant is a clone of the reversed plant, then they're genetically identical and it's selfing). except for the sex chromosome, it works exactly the same as using a male plant.
If yes, do you recommend this?
depends on what your goal is.
Or can i use polens on original plant, if yes, what about the time line?
I don't really know about CS, I've only used STS. with STS you have to count on about 2 week delay for the reversed plant, since it will be ' frozen' for a while after you apply sts, and then after a while(1-2 weeks) it'll start growing again. the rest is similar to a regular male. if you want maximum amount of seeds, introduce the male/reversed female around week 3-4 of flower of the mother.
you can either take clones and reverse one to pollinate another to self, or treat part of the branches of one plant/use a low dose so there are only a few male flowers, so it's all on one plant. both work, I think using clones would give slightly better seeds(I noticed on partially reversed plants the seeds mature less and stay smaller, but that's mostly within the same buds, if you treat one branch and have another untreated branch it should work better, and they still mature enough to be viable seeds).
I mean since its an autoflower, things are a bit under sands of time. What if i let the plant do its thing and pollinate the whole flowering chamber?
yes you could do that, but you would have loads of seeds, probably way more than you need.
Are those pollinated plants still smokable?
yes, the same as any seeded plant. to be sure I wouldn't smoke the CS-treated plants, but plants pollinated with the reversed pollen that didn't get treated with CS themselves are fine. but like any seeded plant, it'll have lower yield and you have to remove seeds before smoking.
The tent is infected after that? Or too hard to clean up?
I can't say much about that, don't have an indoorspace, I just grow outdoors and sometimes in my windowsill(for pregrowing in spring or for seeds). but I wouldn't worry that much about it, I guess if you wipe all the walls and floors down with a cloth with some water with all-purpose cleaner irt should be fine, or spray everything down with some water.
Should i keep breedinig on new generations and are these seeds identical to their origin?
depends on what you want to achieve. but no, don't count on them being identical.
even if the mother and father are identical genetically, you'll still get differences in the offspring, as long as the parent isn't completely homozygous. so a heavily inbred line will have offspring from selfed seeds that is very similar to the parent, but if it's not already stabilized, you'll still see a lot of variation in the plants coming from selfed seeds.
but each generation of selfing(+selection for the plants you like most) you'll get more homozygosity, and so each generation becomes more stable if you keep selfing(in plant breeding there's a rule of thu,b you need about 6-8 generations of selfing to stabilize a line)
Or any mutations are expected? (On same plant, or x-cross)
this is a bit of a though question, I have 2 answers depending on how I interpret the question.
ignoring weed-terminology and going by definoitions from biology, I would say no: mutations occur constantly, but it's not really something you'll see a lot of, and the rate of mutation is constant, so you won't get more or less mutations due to how you make the seeds, unless you use mutagens like colchicine.
however, I think I know what you mean, and it's not that. the thing is, mutations happen constantly, but they usually stay invisible. when people talk about 'mutants' with weed, it's not like that mutation only just happened, it was there all along, it just didn't show.
and in that case, yes, it's likely you'll see more 'mutants' if you keep selfing seeds.
the thing is, usually mutations are not good. usually, something gets broken('loss of function' in biology terms). however, since there are 2 of every gene, usually that 2nd 'healthy/normal' gene is enough so you won't see anything wrong. and since there is nothing wrong, there is also no selection against the mutation, so it stays and gets passed on.
but by selfing you'll get more homozygotes, also for those mutated genes. and that's when you start seeing 'mutants'. but it's not new mutations, it's existing mutations showing, it's inbreeding depression.
however, you can't do stabilizing without inbreeding, so it's a trade-off. you can focus on preventing inbreeding depression at all costs, but then you'll never stabilize anything, or you can stabilize to the extreme but then you'll have a mutant inbred redneck-plant.
