For all who breed cannabis. I have questions.

[Guest]

How exactly do you go about making crosses that will fit and make a better plant rather than a mutant. And also what do you look for in males and females before breeding them together.

Selfing Plants for Seeds:

How exactly is thise done to artificially make and select the correct male.

and for Cloning:

When do you take clones of your plants froms seed? Do you just make you seed plants mothers if you want clones growing instead of plants from seed.

Also can you take clones late in flower if you find a really good keeper pheno, or would you have to reveg it.

Im looking for the specifics on some strains such as hogsbreath, p91, purple urkle, the purps, and also Arjans haze from holland. How were they made(parents), how does yours smoke that you get in your area.

 

[Guest]

at least a source of information for each? thanks guys.

I guess the second you step outside discussing what seeds you wanna buy from a breeder no one cares.

I dont think mutants are really a common occurance...And depending on your goals selection would be made for plants that are vigorous looking for good yields, taste smell, plant structure, type of high, potency, and flowering time..

Selfing a female plant to produce male flowers can be done by stressing and the use of chemicals.

Personally when takin clones i take them bforwe the plants from seed go into flower and keep the cuts from the best plants after harvest..

hope this clears some things up for you...btw i am not a "breeder"...peace

POd-

I'm not a "breeder" yet, but I've been doing a lot of reading and info collecting about the subject because I find it interesting.

First, you need to have a goal for your breeding. What characteristics are you looking for? What do you want to improve? Do you want yield, flavor, color, early maturation, strong stems, head buzz, body buzz, or ..... ?

For example, some varieties of cannabis produce very well but are lacking in flavor. To improve the flavor, you look for another variety that is compatible with the features you like (good production, good potency, looks, or whatever your goal is) yet has better flavor than the first variety.

Select parents that each have as many of the features you want as possible and combine them. This makes F1 hybrids, assuming you are starting with stable varieties or IBL's to start with; if you started with hybrids that aren't stable, then you get a polyhybrid, not a true F1. If the parent plants aren't stable varieties, you will get a lot more variation in the first generation than you would if the parents were stable.

Grow out the seeds of the resulting cross and choose the ones that best fit your ideal to continue working with. Cross them to create F2's. Grow out the F2's, select for features again, and cross them to create F3's. And so on and so on.

You don't generally run into inbreeding depression until a few generations into the cross. One way to help prevent this is to run two separate lines of crosses looking for the same goal and don't combine the two lines until the final step. This final combination should (if all works right) eliminate the inbreeding depression and result in a fresh hybrid because of the different genes in the two lines.

One of the best sources of information is Clarke's Marijuana Botany book. If you want information on breeding in general (not specific to any particular plant), there are any number of books and websites out there.

There are several methods for selfing plants. There are a couple different chemicals that can cause plants to reverse sex (these chemicals can be very hazardous to handle, I don't recommend trying them). You can light-stress the plants to cause hermies - this can result in more hermies. Letting a plant go beyond maturation in flowering (around 2 weeks past prime) can also cause a plant to produce a few male flowers in a last-ditch effort to reproduce; collect the pollen, dry it, store it in the fridge with some dessicant, and use it to pollenate the next set of plants. This last method is supposedly the most reliable to not get hermies.

For taking clones from seed plants: I let the plant grow to the 5th node or so and then top it. This encourages branching. When the branches are at least 3" long with 2-3 nodes each, I cut them and root them. Age of the seedling depends on variety, but I find it's usually 3-4 weeks from seed to take clones.

Plants in late flower are very difficult to clone, but you don't lose anything by trying. It will take much longer for the cuts to root (possibly a month), so take great care with keeping them from drying out & dying. A foliar spray to seal in moisture will help a lot. Revegging doesn't always work, either; the plant is at the end of its life cycle and may not always pull through. You will see a lot of mis-shapen twisted leaves during the revegging or cloning process later in flowering; don't be concerned. Once the growth establishes itself, normal shaped leaves will reappear.

heres a possibly impossible question. How do you take a selection of cannabis plants and simply breed for pure potency over and over and keep improving it. Is there any sure fire way to just keep driving up thc content or is this just an act of good selection and a little luck.

I think someone from norcal will be able to shed some light on my strain selection as well.

And when you clone all you do is simply top the plant with a decent size branch cut at 45 degree cut into multiple more brances at 45 degrees then diped in the rooter put in the little cloner cubes cut the tips (optional) and then spray with water and cover up under some decent floros. Seems simple enough.

there are many ways to clone, best to start with a healthy mature cut(alternatin nodes). I like to do most everything as easy as possible, and clonin is one of um. tried numerous techs, and i just take the cut, dip in rootone, and bury in damp soil, no mats domes or anything like that. either makes it or it doesnt. no time to dork around with um. I usually take more cuts then I need, as some dont make it.

hey pod like Ambre said , clones taken in flower can be viable ive cloned buds that were a week from harvest. Expect several months of grow for the plant to revitalize. The problem with crossing strong plants to create stronger plants is that you never really know what the male is going to actually give to you (unless of course the male has been used for breeding before, which also doesnt actually guarantee outcome either) Sometimes shit luck happens and you find the keeper on the first try . peace D.L.

Hey Pod, I found a great book that you might want to check out. I think its Greg Green's newest book, The Breeder' Bible. I am finding it kinda hard to grasp as there is alot of info to take in, I find myself having to read alot of it over and over again till I understand it.

 

[Verite]

Someone should write a book about all this plant breeding info.

 

[sunnyside]

they have...there are many good books out there.

 

[glasspackedbowl]

I have tryed Hogs Breath and it was very nice super potent smoke. I got a few seeds from that quarter I got. Dont know about how it grows I got mine from SanDiego

 

[guineapig]

Lots of good guides to Cannabis Cultivation out there.....

Of course Robert Connell Clarke's "Marijuana Botany" is still
an incredible resource (even if some of the chemical steps
in the synthesis of Cannabinoids are a bit outdated........)

But as for Greg Green's book "The Cannabis Breeder's Bible,"
lets just say i'm still waiting for the definitive resource for
Cannabis Breeders....but his Grow Guide is quite good.....

kind regards from guineapig

 

[Verite]

But I only like the ones where the first chapter is on sarcasm.

 

[Guest]

I would be better if books were just a big set of diagrams that help you figure shit out on your own. I hate reading off pages, to me it gets monotonous and boring no matter the material.

I got this book as a christmas present this year! Already have Marijuana Botany.
