Methodologies for generating variability

[Tonygreen]

So I was reading this

Apparently these guys will irradiate your seeds for free.

They say a lot of place will offer seed irradiation service. I wonder if there is one where hemp is a legal crop?

BUMP!

To establish necessary treatment levels they're talking about using four hundred seeds for each test treatment (recommending four or five treatments). And that is just to establish a dose that won't inhibit growth/germination/death rates. After selecting the right dose you'll need even more seeds and then select desirable phenotypes... Not to mention that cannabis is not nearly as stable as the rice and such they are describing, complicating things tenfold. Really unless you're running some outdoor gueriila grow in the mountains it's not exactly realistic (and not really advisable to get your name out there by sending a lab thousands of cannabis seed).

Then there is question why? Cannabis already has more variation than any individual/breeder could possibly wish for. Heck even very thoroughly bred IBL "strains" usually show numerous variations when grown from seed (more of less depending on breeder, but never ever none). Simply poppin' random bag seeds will give you a huge selection with definite keepers (I've seen some gems from bag seed seriously)

Just IMHO

Interesting topic. I'm not sure how I feel about intentionally inducing genetic mutation in your seeds via either chemicals or radiation.

 

[purple_man]

it's a pretty wide-spread breeding tool... lot's of commercial fruit lines been bred via irradiation induced mutagenesis. the basic idea is to increase the frequency of mutations which would occur naturally on it's own, the hard part is working through the thousands of seeds to find out the right dose, and test all the survivors. sending in c. sativa seeds could be sketchy, if you ain't got a contract with a university or such...

blessss

Keep a pack of seeds in your shirt breast pocket when you get X-rayed at the dentist, or tuck some in a roll of saran wrap underneath your shirt collar.

Hemp seeds are legit in some places.

Thanks for posting that pdf , best guide to the subject i have seen.

You could possibly replicate every documented sport/mutation attributed to cannabis plants and generate some new non lethal ones , but the numbers required would be daunting and more applicable to a field crop puling a handfull of contenders from thousands.

Stabiliseing a rare sport would become another huge numbers exercise as it probably wont breed true.

X rays seem to be the only DIY option useing industrial weld testing kit or an old dental machine if its powefull enougth , Cobalt 60 would be best but too much paperwork nowadays and licenseing required to hire it.

Proton beam is being promoted into the food crop research area , claiming good results and killing less seed in the process , serious money being invested in Japan and China on research hardware.

Dont have a big problem myself with radiation induced mutation , as it is the driveing force behind evolution just at an accelerated rate.

Need a colorado homie to see if we can get something going heh

Fuck I wonder if they will do pollen... haploid cannabis mmmmmm
