crossing stains

[jr0ck]

This is definitely for further down the road. But I had an idea that turned into a question...

So if I stress a female, I can make her go hermi. This would cause her to be able to self-polinate, which would allow me to create feminized seeds for future growing.

Now what if I have two different strains. If I make them both go hermi, and then polinate each other... will that create a cross between them? Or will it produce one or the other depending on which genetics make it to the seed?

You'll get a hodge podge of seeds. A good 95% of them will have hermaphroditic traits. Probably 1/2 of them would be straight herm no matter what. The other 1/2 would decide male or female as long as no stress was present. Then there would be that one seed in twenty that was just pure boy or pure girl.

The best way to breed is to use a good 50 seeds of both varieties to completion with high stress levels to isolate true males and true females. Keep them separate during growth, clone the true breeders, and then select the most resinous male with the characteristics you like (vigor, color, height) to breed with the true female that has the best potency and also some ideal characteristics.

This creates a pretty stable F1 generation for you to play with. If done right you can have thousands of seeds.

Growing out the F1 generation you basically find traits you want, further isolate out the hermaphroditic tendency (you will never get rid of it, but you can increase stability), and continue to breed this generation together, building F2 and F3 generations. From that point you can then select another strain with desired potential, like Chronic's yield or Durban Poison's cerebral high or others, and create an F1 generation with good variety that you can then hone down.

Establishing a genuine and true strain could take 5 years to do proper. Many breeders don't spend the time needed to exclude hermaphroditic tendency. I would LOVE to breed for a living and have only been reading up on genetics for the last 2 or 3 months. It's a big field.

But for the normal at home grower you can just cross whatever with whatever. Play the numbers game and plan on 1/3 of the plants male, 1/3 herm, and 1/3 female.

I dittyo poster above... if/when i decied to breed i intend on staying far away from hermies/fem seeds

i also don't want to discourage experimenting so keep up the creative walk

Selfing is good if you're moving across country or something like that and want to take seeds of a particular strain or cross that you can't get otherwise. Otherwise I kind of feel like it's like incest and stops the natural evolution of the cannabis plant. Just my opinion. Like Stay@homeGROWER said though, I encourage experimentation so go for it and post the results!

I get what you mean about the herm characteristics being passed down. But it really would matter where the threshold is. Having the plant turn herm when you want it to wouldn't necessarily be a bad thing. It's just when it shows up in an undesirable manner. The project is going to take a while. I am going to finish the grow I am working on now. Then I plan on ordering a few different types of pre-fem seeds.

Once I havest, I am going to try and put them back in the veg cycle and see if I can get them to grow a bit more(now I have at least one harvest from them to tell their potency, and I know their sex). So if I stress the females, I could potentially turn them herm. From there I was thinking I could start crossing the types, and worry about breeding out the herm trait after(depending on how good/bad the plant incest turns out).

The two big ones on my list are the Reserva Privada(http://www.cannabis-seeds-bank.co.uk/images/uploads/OG-Kush-cannabis-seeds.jpg) and the White Russian(http://www.cannabis-seeds-bank.co.uk/images/uploads/serious-seeds-white-russian.jpg). I love the look for the Reserva Privada seeds, and I love the yield of the White Russian. I suppose I could do it the right way and get non-feminized seeds, and save some of the pollen from the male. But where is the cool science in that?!

This statement kind of contradicts what i've been reading. Supposedly, if I hermie two females. Technically their seeds should be feminized right? So then by taking two females that I force to become herm, I assumed the results would be females with the potential to be herm.

Furthermore, I figured if I did it to a few females, and only took the ones from the female that took the longest to turn, wouldnt those seeds have the least possibility of being a herm itself? Or am I over analyzing?

It's how the plant is turned hermie that determines whether future seeds will produce hermies - if the plant is easy to turn hermie then the seeds will carry that genetic tendancy.
If the plant doesn't turn hermie without some serious and deliberate action on your part, then the seeds should also be difficult to turn hermie.

If you want to create all-female seeds, just use colloidal silver. Here's a link, Producing Feminized Seeds Using Colloidal Silver, there's instructions all over the place.

Forcing a plant to hermi is just kinda guess work. And, paired with the fact that if they show hermaphroditic tendencies, they probably carry hermaphroditic genes, stressing a plant to intersex is just not all that great. It's usually best to not have those sort of genes floatin' around in your pool, so to speak.

If you wanted to pollenate another female, all you have to do is: treat the area that you want to be treated, collect the female pollen, and pollenate said female.

ooli, thanks for the info. I will probably go with that method when it comes time.
