Genetics question, mutant leaf strains x auto trait, what are the challenges?

*punnet square .. misspelled it.

leaf mutations are not related to autoflower trigger for flower phase. mutually exclusive bits of DNA code... so same process as always to get there. Just have to make sure the trait is present and its offspring regularly display it.. this is learned through hindsight.. use multiple plants and test offspring. The plants that complement each other the best to have these traits will have a higher probability of offspring displaying those traitns. Unlless you hve the roadmap for these "alleles", you can only learn retroactively by observing resulting rate in the offspring... keep the original 'mother' plants until you figure it out. i don't know exact process, but i thought it took more than 1 generation to get the autoflower flower phase trigger 100% in offspring. it's just math.. a pennet square is a visualization of what's going on with the alleles and why it's just about math/probability.

Crossing a Photoperiod plant with a Ruderal is very simple. It will take 10s of hundreds to find what exactly you’re looking for in the offspring, as others have pointed out. What may not have been so clear is time it will take. You’ll have to make a clear standard that must be met or tossed. If a true auto flower is your goal, this will take many breedings. Time to let it mature, determine bud size and quality, possible back breeding to the parent plant along the way. Anytime you breed or cross back, other pheno’s will be introduced into the offspring. You’re literally looking for a needle in the haystack of genetics. It will take years, I mean up to 8-10 years to get a quality, stable cross, worth growing time and time again. Anyone who tells you they can do it in less doesn’t know anything about crossbreeding auto flower’s to photoperiods or have never done it. Crossbreeding Photoperiod plants may not take as long to get the cross you want, you could get lucky with just a few cross breedings. Autos are a very different scenario in the weed world.

Its not as easy as just making it an auto. its a different species of plants in the same family. They might be able to cross a few plants with autos and then back cross them each other and try and get the pure auto traits out of that. But autos versions of all plants are not the same as their photoperiod counterparts, similar but still different. then add on to that the desired trait of "mutant" growth. and it complicates things. Good thing is that you can grow photoperiods like autos. just go 12/12 from seed and it will act like one. Or just do 18/6 for the first 4 weeks and then switch to 12/12 right away.

I have not grown this particular mutant strain but in my experience most genetic mutations are not stable in cannabis plants. Some noteworthy exceptions would be duckfooting and possibly the ABC form (and possibly that new vine growing strain???). Complications trying to auto a mutation would likely be keeping the mutation consistent across the generations required to get to autoflowering and a semblance of stability. Further complications, the mutants I have had in my tents have handled stress poorly, shown sterile intersex flower tendencies, and be extreme feeders (all annoying in their own ways despite how cool the mutations were). I know CSI Humboldt has been working with the ABC a ton lately, and he is connected into the old PotET and newer circles. I'm sure if you could ever get ahold of him he would have some great info to opine with.

You could cross it with a pure Ruderalis plant, then do a pheno hunt to find the offspring carrying the desired trait. Ace Seeds have some quite pure Ruderalis strains at the moment. Fixing the desired trait may take many back crosses and selfing, however with a non dominant trait, this might take 100s of seedlings to establish. Crossing the Menth de croco wth a random, already available and desirable auto male would produce a mixtue of offspring.........some being regular photoperiod, some being "fast flowering" and some being autos. You would then have to back cross the autos a number of times to fix the auto trait, then at the same time hope that some of these carry the leaf trait you seek. Again, this may take 100s of seedlings to establish. It won't be a easy task, but is worth a try if you have plenty of space and a huge amount of time. Every journey starts with one step, followed by another, followed by another...........starting is easy, following the path and not straying from your desired goal is a lot harder.
