Question about crossing two strains

[Big spliff93]

I just started to grow again after years and am really enjoying getting back into this hobby. I would like to make my own seeds.....
Anyways my question that I would like some help with is. If I have two strains I’d like to cross with multiple males in females of each strain. How do I choose which which strain will be the Male and which will be pollinated? I know to look for the most desirable of each one...
I’m not sure if my question makes sense hopefully someone gets what I’m trying to relay.
Anyways here’s a pic of what I got going at the moment

Simply run a table with both males and females from each strain

The male is going to impart slightly more generic information into the cross then the female. Breed the brothers of the females you like most to the other strain if your determined to make the cross.

Not that I’m determined to make a cross I just would like a seed stock. Might try the colloidal silver route. But I’ve heard I can get Herms.

Wish I had the room and resources.

Then run a male from one and a female from the other. That's fewest you can do. It works and you'll get seeds.

You can't tell how good a male is just by growing it out and rubbing the stem. That's why crossing/selfing females is the fastest and easiest way to get the best seeds you can. Silver thiosulfate is a lot easier that colloidal, only needs to be sprayed once or twice. The herm myth came from "Rodelized" seeds which nobody makes anymore, it doesn't apply to modern fems made with silver. Herm comes from genetics, so don't select parents with a tendency to herm.

Cool so the hermie thing is debunked. I’m ignorant when it comes to all this not looking to create the next greatest strain just want seeds. I’ll give silver thiosulfate a go

You're not ignorant. There's just so much nonsense out there that it can be difficult to know whats right or wrong even for intelligent people.

Applying Silver Nitrate & Sodium Thiosulfate Mixture for Fem Pollen

This is the mixture I plan to use (first time - feedback welcome) 0.1 grams Silver Nitrate + 100ml H2O 0.5 grams Sodium Thiosulfate + 100ml H2O + 500ml H2O Glass Jar For female pollen sacks- Fem Seeds (do not ingest these chemicals- wear nitrile(?) gloves when applying) My question is this...

Unless they've changed genetics since I was in school it's an equal amount of information from both parents. Could you share your source with me please?

What are the two strains? Out of curiosity...

 

[DrOgkush]

Iv been told that the most natural breeding methods (male to female unrelated) then re crossing brothers with sisters to achieve crosses more predictable. Or stable.
But iv never done it. Iv done no research on it either. I usually keep a male that bushes like a female and has unique traits different then the rest. But that's just me. And that breeding method is not facts. Just bro talk but the guy who does this has always grown flower perfect imo. Trusting source for me.

That's a form of line breeding and breeding closely related plants will decrease genetic diversity. You can also back cross within a line. It's part of stabilizing stock.

I do look for the best males when I'm actively working on a cross but when I'm doing reproduction runs of landrace strains I usually just mix the pollen from all the males I might have to ensure as much natural diversity as possible.

James Bean show featuring Mr. Toad from Boneyard Genetics. Mr Toad cites a scientific study and shows the credentials of it on screen. A little tedious but quite insightful. Was news to me.

I usually cross unrelated. Because I used to breed cockatiels and amazon parrots for mutations (diffrent colors) and related offspring were unhealthy and frowned upon.

Not right. So as for plants would that be a problem to interbreed. Creating defects ?

Agreed. I tend to pollinate every year my more expensive and rare strains to keep that in stock however. Always wondered how to preserve specific without self pollinating

Actually I'm wondering if they are considering the weight of the larger Y chromosome which is important in terms of sex selection but not overall diversity.

Anyway I'd love to read that paper.

That's why I usually start with an open table pollination. That way you get the maximum genetic diversity. After that first run you can start to sort traits and start to follow and reinforce types you prefer.
