Is this liquid gold?

@sir_isO Thanks ure right for once; ill try surflan. STS is best method for making fems. Im sure you breed with cows. Theres nothing wrong with fems. Yes like your parents you have no intention of producing anything good.

Colchicine is something I'd personally stay faaaaar away from. Chances of finding something useful is very low, it's super toxic and at best vague in terms of use. I reckon you can get polyploidy without colchicine, with the right sort of parental chromosomal combinations (though how that's determined is something I have no idea about). I do believe it has to do with differentiation though, so you need sort of complementary but different parents...based on pure speculation. Signs of polyploidy, afaik, is general "oversized" sort of features. I definitely have some strains that are rather freakish in that sense, and they were from almost random pollination. I say almost, because there was crude selection involved. If they're actually polyploid, I dunno.

Can't help you, I breed but never with STS. Personally I find it degenerate, but I have no intention of producing like commercial seeds and whatnot.

If you have a lot of female seeds, why don't you try to use colchicine during germination to induce polyploid thingy. Once a polyploid, the off spring stay polyploid.
