to simply answer your question... no, your seeds will not be autoflowering...autoflower gene is a recessive trait...
auto x photo = photo (with auto gene)...
photo(with auto gene) x photo(with auto gene) = some autos (50%-perfect world)
those auto x those auto= % go up, and you keep on crossing the autos one day they will be 100% auto...

The cannabis breeders bible says it's a dominant trait I would love to know if you test them how it turns out I'd love to try some and I plan on doing the same thing intentionally sometime in the future

Well, having a dominant autoflower gene would make retention of the autoflowering trait during selection a lot easier, that's for sure.


It could take fewer generations, I think.

At this point, though, many if not most of the commercial autoflowers are already 8-10-15 or even more generations bred away from the original hemp-like ruderalis plants. Apart from the autoflowering trait itself, these don't retain much, if any other ruderalis genetics at all.

Remember, with appropriate selective breeding, you can reduce the percentage of autoflowering genes by 50% in every other generation, just by backcrossing to a photoperiod plant. After ten generatons of crosses and back-crosses (ie just under three years of work), you can turn a line from 50% ruderalis genetics to less than 2%, and that's without any selection at all. This also assumes you're starting with a pure ruderalis plant. If, instead, you're starting with an already worked line, you're probably starting with something that has less than 10% ruderalis genes to begin with.

As a related issue, I think its an open question whether or not just having an autoflowering gene in a plant affects its potential potency.

Emprically, there are any number of fairly potent auto-flowering strains out there now (eg 60 day Wonder is supposed to be pretty potent, as is Paki Kush ryder). So its certainly possible to have strong auto plants.

But if this is true, you're just never going to have autoflowering plants as good as the best regular photoperiod ones, even if you were to exclude 99.999% of all Ruderalis genes from your line.

You need to do research on in bread pure lines and breading with hermie

Everything I've read says auto flower is dominant

If it was dominant, all offspring would express the auto flower trait. But f1 with photo and auto none of will be autos. Only some of the next generation.

I know I'm coming in late but I have just put together all the components to make STS solution to produce pollen on a female plant and use that to pollinate another female plant. According to everything I have read the resulting seeds will be 99.9% female. My question is if I harvest pollen from a female autoflower and then use that to pollinate a female photo the seeds should still be female but what percentage will be autos?
