So if you have an S1 because that’s the only form your strain in available in but you want to make Regular seed for whatever reason does it make sense to breed it with another strain and just hunt for it? Should be easy to find in an F1, correct? Everyone is making all these S1 seeds but I’d rather have regular seeds so I can make more.
F1 is 50% mom and 50% pollen donor. You can find expressions leaning to ether side but it’s still 50/50. Back crossing is what you need to do to capture a clone in seed form. Takes a bit of skill to do it well. But here’s a nut shell breakdown. F1 = 50/50, Bc1 =75/25, Bc2 = 87.5/12.5, Bc3= 93.75/6.25 ect. Bc4 is generally considered a consistent/stable representation while Bc6 is the base for it being considered an inbred line.
You could keep S’ing to stabilize your own selection and use that for breeding. If you’re looking to make a good F1 that resembles the strain in F1 than you could find the parents of the S1’ed strain and BX than if you save the S1 mother, you could take that BX to like F3 or F4 and than continue BX’ing to the S1 mom for stable regular traits.
Depends what it is the more inbred/true breeding it is the more chance the S1 will have of being “close” to the mum so you could just make s2s and hunt them but if you want it reg form then you could totally do a bx line with it but you are best not going above bx2 if possible in a ideal world as anything past it isn’t so healthy long term for a line so hopefully you can wrap it up n be happy with it about that generation unless you want a big project then look into recombinant inbred lines it keeps more vigour Vs straight bx work but there’s more work to it obviously
Yeah I agree with this statement, if your goal is to have seeds for growing then S2 or BX is about as good as it gets. Going further will just lead to worse stability unless you’re fully committed to working the recombinant line.
Ok cool. So last question. If some say they have a Hindu x Chem D (or whatever cross you can think of) Is it assumed it’s an F1?
Usually yes, otherwise they will state this is Hindu Kush x chem d f2
Assumed yes as the true lineages of chem is unknown we can make some guesses but that’s it
