Hey this guy gets it, punnet squares. Add into that some statistics and you are creating replicatable results.Learn about using the Punnet Square.
Without backcrossing you’ll probably get all autos after the third generation.
Then you need to stabilise the Auto phenos ,,selecting for
height , smell ,yield etc. Backcrossing after this stage may help speed things up.
The above is to the best of my knowledge,
You're post has a lot in it to unpack and there heaps of questions of in there let me start with this bit. Yep I think you're right here although, I also think if someone is up to an F19 that have have forgotten why they even started and are looking for something totally new. Alright ok though, If you're chasing some particular traits in a plant it's easy enough to chase it down and isolate it within a couple of generations. Now though, seed will NEVER come true to form. There maybe a change that you don't realise such as water use, pest resilience, leaf blade thickness any number of things. Best bet is that you combine the things that you love about plant enough times that you get what you're looking for nearly all of the time. WooooIf you were to cross it being a hybrid/polyhybrid it is, the resulting generations may not be so easy to isolate those traits (mutant leaf/purple bud) as quickly because the hidden traits of the plant it was crossed with
Punnet squares and a population of 30 would mean you will get 4 of your desired results. If you didnt 4 you start again with 30 until your get your 4 desired results. take those 4 rinse and repeat until you get 4 8 16 20 24 28 you will never hit 30 and you will never hit 100% but 28 out of 30 aint bad.If I wanted a reg Drunken Bastard auto.. and threw Male photoperiod DB cum over say a Duck’s foot auto.
Selected from leaf shape and auto flowering tendencies at 18hrs over 4 or so back crosses.
Whats the likelyhood of achieving a DB-ish reg auto ?
To much N will make it hermie!It will be a lengthy process. You won't get any auto offspring from your initial cross of photo x auto, but you will see roughly 25% auto offspring from the crossing of their f1s. From there you can start you selection, but locking down both leaf mutation and auto dominance could take a lot of work.
In the mean time Rocbud has already done all the hard work for ya with their Auto Purple Bastard Eater .
Yeah, seems like a bit of a cop out for questionable breeding practices . Rocbud generally has a good reputation, but has also faced their share of controversy in the past.To much N will make it hermie!
I've been hearing this a lot lately on the US forums!
Can't seem to find any evidence just heaps of bro science!!
Must say most of the time I've had hermies I don't think they were heavy on the N.
Last 2 grows for me were both N heavy and no hermies!
