Understanding breeding, how to achieve the best an strongest high, false beliefs an inbreeding depresion

I’d think starting with plants you like to be a good first step :grin:

Say you start with a skunk and a mexican sativa…

One way to do it is to grow some of each, and choose one from each line you like, then cross them…

Another would be to select a few superior plants from each line, go the selfing route to validate who’s a better outcrosser and then mate them.

Yet another would be to keep maybe 10 from each line and open pollinate.

Each has its ups and downs, but will get you to your goal…

The thing with breeding is that the prettiest plants aren’t necessarily the best breeders. I think the selfing method can be favorable in a lot of cases, giving you a chance to filter and cherry pick before moving forward…

Ps
Tom never used these schemes, he was too busy preserving his old lines and I think I heard he started to self all the worthwhile cuts and grading them or something.

I was just going through the above example…

Personally I’m on the fence about backcrossing, it can be useful in specific scenarios, but here I think looking through any early recombination would do it.

I prefer f2s, but my goals may be different than some. I like to hunt the rarer recessive crazies lol

Makes sense, thanks for going through that :+1:

One thing I’m not sure of in Tom’s scheme is: what about the males?

I realized I pretty much walked through that whole process mentally with females only and using reversals for pollen.

If you are selfing both parents, then you are basically working with females as both parents after the initial cross (unless I’m missing something).

Which is probably fine as far as I understand, but maybe I misunderstood :thinking:

I’m merely offering knowledge and thoughts on the subject. Not step by step how I do things. Please don’t assume what you don’t know.

Actually, what you are doing is presenting your method (cherry picking males) as the superior strategy, while also exposing your ignorance of the huge importance of open pollination–like how you believe “open pollination” means no improvement in the line, and gloss over disease resistance and the preservation at all costs of genetic material, like that is completely unimportant.

I grow medicine for my wife and I and that’s it. I don’t grow outdoors, nor do I clam anything I make is good to grow outdoors. Its not even legal to grow outdoors where I live.

So now it comes out that you are not actually doing serious breeding work aimed at larger goals, but just propagating smoke for your close family to use. (And that’s fine, but…)

And you don’t even grow outdoors, because “it’s illegal.” How many people do you think are in this thread and on this forum who are violating the law in some fashion, whether they know it or not?

Do you only avoid outdoor growing because of the legality, or perhaps because you know or suspect that your genetics would get wrecked out there if subjected to the full force of Mother Nature?

If I do make beans I document everything for all to see and share the resulting beans, usually right here, for free. I don’t charge for anything so I don’t know where that’s coming from.

I don’t care if you charge or not; that’s not the point. You’re perfectly within your rights to make whatever beans and sell them for whatever price. I would actually respect you more if you did that. The point here is you are running a very limited operation with very limited goals, and trying to argue me into the dirt acting like your method of doing things is better. No, it really isn’t. Furthermore you are causing harm by misleading newbies when you claim such.

To put it bluntly, if people stopped producing heavily inbred cannabis lines in their closet, drug cannabis could still survive and thrive worldwide. If however people stop growing and producing open pollinated lines outdoors, drug cannabis will then be well on its way to extinction.

I’m merely stating males can be quantified the same way females can

WRONG! NEITHER MALES NOR FEMALES CAN BE FULLY “QUANTIFIED”! Did you even read what I wrote above, before responding? Or are you just stuck in this loop that you will never break out of?

Those four F3 keeper plants that I spoke of earlier, which outcompeted and dominated when the majority of their sisters were destroyed. How could you have possibly selected THE male father which would produce such plants, out of the 60+ males that were grown in the F2 generation? X-ray vision that lets you know exactly which male will produce what, when you couldn’t have even looked at one particular female and known it was anything special, without cloning it and growing it in a different environment? Cross a promising female by each individual male and grow out the resulting 60 crosses to “test” them? How could you possibly do anything like this? Why not just open pollinate the fucking plants, grow out the next generation, and let Mother Nature do the testing and selection?

If you’re not breeding anything outdoors to begin with, then what the hell are you doing, exactly, in an “Understanding breeding” thread acting like you are an authority on the subject?

We’re breeding for entirely different purposes. You can have uniformity at f2 and f3 with the correct selections if that’s what you want. It’s all about goals.

Yes, it is clear we have completely different purposes. You want to breed bottlenecked indoor-only strains in your closet, for your own personal use only. I’m trying to do something that will make a broader and more lasting impact on the cannabis world, hopefully contributing to longevity and health of the species as a whole. Your next to last sentence, highlighted in bold, explains it exactly as I said it above: your #1 emphasis is on SPEED above all else. That’s an extremely shortsighted mentality. Even in your limited circumstances you would be better off using open pollination instead of all this heavy inbreeding, but you simply refuse to hear it.

Yes, using this scheme both parents are females.

You can reintroduce males once you have reached your goal on the female side.
A male from an inbred line would probably work very well, something f4 or further…

Now off the beaten path we go…
Selfing a male using etephon (sp?) makes m/f line, although heavily favoring male progeny… 66/33 I think.

I wonder if we could evaluate males in such a way by looking at the females from the male line.

You are correct, you cant preserve something in seed form, so that makes it impossible to maintain.

What the hell are you talking about? What do you think Afghan farmers do every year? You think the average farmer there is growing out 1000+ plants every generation?

“You can’t preserve something in seed form”? Yeah you can, happens all the time. Now if you mean making an exact copy of some highly inbred F1 hybrid clone you’re so proud of, then no, you can’t do that. But if the farmers doing open pollination outdoors weren’t doing their thing, it wouldn’t be long before you didn’t have any solid genetics in the first place to bastardize with heavy inbreeding and excessive selection pressure. Doing things exclusively your way, cannabis soon goes extinct.

This idea of “just self a plant a few times, cross with another highly inbred plant, and voila! got all your genetic diversity back” is a laugh. Yeah, right. If you want to quickly destroy the vigor and vitality of a line, a great way to do it is a bunch of selfing. Following that up by crossing two inbred, bottlenecked plants together is not some magic tool to get all that genetic diversity back. Once a gene is bred out of the population, it’s gone, and isn’t coming back.

Bored again today?

I can’t select for what I can’t see or test for mate, and neither can you. Simple as that.

I select for what I can for my own projects, and I’ve been successful in my goals and methods so far.
You can test and select for more things, you’ll likely have a better chance at a stable line regardless of environment. And be successful selling it or whatever you wanna do.

You argued you can’t select males at all and to just use all of them.

I’m saying there’s only so many phenotypes that show up, and they’re all gender neutral. Just need to look at the plants and choose accordingly. Take some responsibility instead of leaving it up to random chance or “nature”.

I’d also much rather pick a couple plants and test and go from there, than to pick 50+ and only get to see a couple beans from each girl. I’d much rather look at 50 beans from a single pairing. If I messed up somewhere along the way, I can always go back and start again at any generation. It can be quicker, or longer than what you’re doing. Sometimes it is what it is.

Lets move on.

I follow tony on IG and every once in a while he’ll get in a fight with someone on breeding…and he just does this scorched earth campaign on them lol…that’s how i know he knows what he knows

Tonygreen (on Instagram, of all places) is your idea of an expert breeder? I know Tonygreen from ICMag (not Instagram, which is a cesspool) and I wouldn’t characterize his advice or knowledge as being particularly special (same for most online commenters also), but what do I know?

When you stop getting your breeding advice from hipsters online, and stop pontificating online about the subject and just get out there and grow some damn plants, you will find the plant itself gives you much better knowledge and wisdom than anything you will obtain online, even from old time respected names, who in some cases are completely wrong in their ideas.

Lol you’re getting pretty mad here dude :rofl: :rofl: :rofl: :rofl:

Isn’t the purpose of trolling to get other people angry?

I assume you must be a troll because you show up here with no history on the site and proceed to belligerently argue with other people who have all remained civil.

And what are the credentials you provide to preach from such a high place?

A few mediocre looking plants in veg… LOL

This troll attempt gets a 1/10 at best.

Please get some thicker skin before you get on another forum and end up trolling yourself into a tantrum.

You’re in your 20s, right Mudballs? Want to know how I know that you’re a young guy?

One personality flaws that I’ve noticed in your comments in various threads is that you tend to be angry and defensive when anyone tells you that you’re wrong about anything. Like for example that time when you got “triploid” and “trifoliate” confused. But the good thing is you do eventually seem to listen to reason and integrate it into your knowledge base. For that reason I will ignore your aggressive response, and wait for the time when you calm the fuck down and listen to what I’m trying to teach you here.

I would also highly advise against going around online or anywhere else talking about how you are growing 300 plants in Texas. I don’t even grow over 100 plants anymore, because the Federales have historically frowned on 100+ plant grows. The current state of the cannabis world, where restrictions seem to be lifted and we’re well on our way to nationwide legalization, is extremely dangerous as it lulls people into complacency and a false sense of security. I can see how the winds are blowing, and it seems very likely the cannabis community is being set up for a repeat of the late 80s and Operation Green Merchant within the next 5-10 years. So learn to take your security extremely seriously.

Im not growing 300 plants in Texas…guess you didnt read the part where i said i am not willing to risk that yet…i get it…no point in reading when ur just here to get ur point out.

You cant preserve a seed line because of random mutations in the gene that happends everytime you breed. So the genes wont preserve. They will evolve over time into something else. This is called evolution…

Even if you had 1million plants…ok imagine an entire huge field like in Oklahoma…just miles of the same strain…over time there will be tiny hotspots of that very mutation…that hotspot will grow as offspring continue to carry the new look.
If you’ve ever seen a ‘heatmap’…for anything it’s just an example, that’s a good example of what would happen in a population of dioecious plants monoeceious might act diff. Like looking into a pot of boiling water
