Crossing strains

Hi guys,

I would like to cross feminized seeds with regular seeds. Can someone with experience explain how to do this right and is it a good idea?
The grow room could only contain one large plant. Then I started reading and it got too complicated around the genders and feminized seeds.

1. My idea was gathering pollen from a Mango Haze male and pollinating a Mimosa Evo female. Then crossbreeding to stabilize.
2. Afterwards I read that it is not a good idea from another source, since the Feminized seed contains only half the genes and breeding this way would introduce issues. That the feminized plant can actually pollinate another female.

Which one is true and better to get a good pair of seeds from these parents and is it achievable in this limited space?

Thanks!

You could for example grow the male first, collect the pollen and then grow the female and only put a little bit of pollen on it, to only make tens to some hundreds of seeds(you will get thousands and thousand if you pollinate the whole plant). You could then use the male pollen with those offsprings again to stabilise towards the fathers side more and you would not need to grow a new male if you saved the pollen.

If you pollinate whole plants and make a few generations before you get what you want, well then you end up with tens of thousands of seeds that you dont need and thousands of seeds that are the ones you wanted. But you only need like few hundred to give you life time supply of seeds.. For this reason its good to only pollinate small parts of the plant and you still get almost as much seedless bud from the plant than if you did not seed it at all.

You can use female to pollinate a female if you spray some colloidal silver or STS on it. This will cause it to push out male flowers even tho it is a female plant and if you use this pollen to pollinate a female, all the seeds will be female only. This is how they make feminised seeds. The plant will ofc pollinate itself, which will give you seeds that are genetically very close to the "selfed" plant, but it can also pollinate others, which would be like any cross between plants would be, but female only seeds.

The idea of not using feminised plants in breeding seems to be old news and comes from times where the feminisation was done in more hermie prone ways. Altho i do suspect that you you made enough generations of female only, it could end up fucking up the genetics at some point. So i would say that using feminised is ok in breeding, but it might be a bad idea to use only females for very long, maybe, but maybe it would also be ok. I would not risk it unless i had some science to prove its ok.

That was very informative, thank you!

I Have accidentally had a Louis 8th self seed due to stressing It out and it has created new strain as I had a couple of French macarons in there Which have seeded but not to the extent of Louis so wondered the same are they all female seeds
