There’s a fairly recent thread/tutorial that some dude did earlier this year.

Mother strains will generally overpower the introduced strain in most cases, that’s where strain stability comes into play! The throwback strain is what I tend to try stabilise if possible and have more of an equal mix. Some throwback strains can lead to a straight strain tho as not all throwbacks contain the mixed genetics.
This is just from my own personal experiments over my growing time, different growing methods may have different results compared to mine.

I'm in soil, I am doing feminising with the silver water on a feminised sour diesel at the moment the pollen sacks have started to appear and I'm using 55ppm ordered a bottle on line 500ml $30,i spray once a day,seems to do the trick, I soon will be getting gold leaf pollen and crossing skywalker og, but saves me having to worry about buying more of the same seeds online by making more of what I have, I have not tried autos yet

With crossing your plants it's really just pot luck unless you know everything about the strains

Can be hundreds of phenotypes when you cross some
Can throw just a few with some others

I'd just cross em then grow as many seeds from the cross as room will allow

Pick out any sickly or shit growing seedlings

Veg up a little then clone each one then bud out

Select the best girls then asshole rest

Can use them to cross back onto the pollen from original male that might make a more stable cross .... Mean less genetic variance in the seeds produced

Goal would be to get a strain that breeds true like some skunk and I think northernlights

Cheers mate .....it's pretty fun stuff

Edit : order some books on it , the cannabis breeders Bible and marijuana botony will help you with understanding how it all.works a bit better

Back crossing helps a lot when breeding to bring recessive traits to the fore. The best example would be breeding regular auto x photo period hybrid.

Normally you'd need to breed 5 generations to stabilize the auto trait alone. While your doing this your only breeding with male and female plants displaying characteristics you desire.

Inbreeding brings out recessive traits some of which may not be desirable such as dwarfism. These plants are destroyed and only the plants with desired traits breed. Lines should be created for at least 2 separate females once the strain has been stabilized.

That's my understanding of recessive traits, stabilizing through selective inbreeding and creating IBL. Not that concrete but I guess it's a basic idea of the theory.

Breeding from reversing strains with CS (or alternative) because you have no option i.e. all feminized strains. So if your plants are all fem and no male pollen, reversing is the only option. STS is better from what I've been told by Mongy Man.

Good luck and good breeding. Stay medicated.
