feminized 'S' generations

[Rusty Trichome]

Continuing this from an attempted hijacking, lol.

Stinkyattic: You mentioned that most farmers wouldn't want seeds from 'S' generation femmed moms, so now I've got a couple of questions...

1) For years, I've been using aspirin to induce flowers on female1, and pollinating female2 with the resultant pollen. Is this the same? (flowers start showing too late for viable seeds on fem1, so I collect first few pollen flowers and harvest her, then paint the pollen on lower branches of fem2 which is a few weeks behind in maturity)
No noticible problems with the seeds, the plants, the taste, the buzz...but I do get mostly fem seedlings.

2) Does pollen from chemical induction (aspirin, gibrellic acid...)have different genetic end results than the enviornmental stress induction methods?

3) What's the down-side of femmed 'S' generation seeds?

Thanks...Rusty

edit: I did do a search, both here and online for answers, but found none.

Okay yikes here we're getting into where I'm shaky, lol.

You'd only want those selfed seeds if you had a specific goal in mind and KNEW that the herm was as a result of stresses that you, the grower, intentionally exposed the plant to. For example, you get this bagseed that's the greatest plant you ever grew, and you want to 'back up' the genetics, but you don't know what the parents are, so a backcross is out of the question. You can force-herm the plant and then self it and hope that you get a plant in the selfed generation that is comparable to the mother (and father as it were, lol). The more stable the strain, the more similar the offspring will be.

Answers to Qs as much as I can help...

1) It's close; if you are working with a really stable strain you might as well be selfing the mom since there's little genetic variation at all. No surprise you're getting female offspring; the pollen you are using has no Y chromosome.

2) There shouldn't be any problems with the pollen from a chemical force-herm as opposed to a photoperiod one.

3) Down side? Ehhh. This is where I get shaky. In your controlled indoor environment, expression of a recessive gene that in nature would have made the plant less able to compete is less of an issue. Again, it depends on your goals I guess. So pick the individuals you wish to cross carefully. If you are using an IBL and just want the feminized beans, it's not going to be an issue because you're already homozygous for the stuff that matters.

Don't give me too much credit here... this is just spouting off the top of my head. These are actually better questions for Rhizome...
