Science is a tool, a very strong and powerful tool. It's also a methodology... a methodology that is much more powerful that 'intuition', ignorance, or fear. Science may appear magical to those that don't understand it, but let's not forget that slight of hand also appears magical to the ignorant. There is simply nothing magic about science once you understand that it as a process for learning about the world around us, nothing more - nothing less.

A breeder that knows and understands the science behind their selection processes is a much better equipped individual to make selections, and thus progress within their lines.

Science doesn't replace art, it just enhances it... and a breeder that understands science, only has a more equipped tool-box to use in their breeding schemes.

A foolish carpenter uses a hammer to put a screw into wood, and a foolish carpenter tries to whack a nail into wood with a screwdriver. Intelligent carpenters use the appropriate tool for the job, and any carpenter worth their salt carries a well equipped trailer containing many tools so that when a situation arises that requires a specific tool, the carpenter has the tool on hand to effectively and efficiently complete the task at hand.

How many carpenters do you know that show up on site with a hammer, and chisel and a hand saw? I don't know any that I would choose to work on my projects.

Don't fear science, learn from it... you'll be more effective in your selections.

Thanks for that Coop, I thought I'd re-post it before it was glossed over.

dioecious, (sexually differentiated) Hormonal influences

There are some 500 compounds found in the cannabis species, with only about 80 cannabinoids currently identified. Not all of the cannabinoids are psychotropic. The two cannabinoid compounds in medical cannabis that have been the main focus of research are THC (tetrahydrocannabinol), a psychotropic compound, and CBD (cannanbadiol) which has shown effectiveness in pain management.

420 compounds still unknown and you guys tell me you have all the answers comical.

1. Sativa,

2. Indica,

3. Ruderalis.

Each species carries unique genetic, botanical and biochemical traits.

Each pecies carries unique genetic, botanical and biochemical traits read that agine yet you experts claim to know all .


The genetic makeup of the parent plant determines the potency and other individual traits. Optimal growing conditions allow the potential of the genetics to develop.



There are also two common species of the plant that yield different effects due to different phytochemicals present in each species. Cannabis sativa is reported to have higher THC levels which is more for cerebral-related medical conditions, whereas Cannabis indica is reported to have the compound CBD in greater quantities, which is useful for its anti-arthritic/anti-inflammatory properties.

Hi Hempy,
Have any new updates on the Cannabis Rasta that was mentiond along the boards a few years back? I think the information and studies were from Oz.

So basically what man does is select from whats all ready there and pick out any think interesting and trys to breed things out they dont want like long flowering low yields and and breed in or add things like pest resistants faster flowering increasing yields so on correct.

But it has to be available in the plant or plants being used genetically to start with right.
ined.


Lets face it guys we dont know shit in reality the cannabis plants is only starting to be understood yet we act like we have all the answers we dont.

Id have to ask hempy ,, do you think thc was already in existance at the levels we know now prior to man meddling with it ...???
You mention beginning with good genetics ,, dont you think those good genetics have had mans meddling hand there to get as good as they are?
to mans standards??
nature doesnt breed for high thc hempy ,
but it gave us the beginnings of what we have today ,

as far as cannabis plants go ,, we know heaps about them , its been beside us for thousands of years and we are learning more all the time through science ,
no one claims to know it all , ive not seen one person on this forum claim that ,
but many exchanging knowlege and information ,
theories etc , mostly free of any bad vibes or rudeness ,
except from the odd guy coming in saying stuff like

"you guys know nothing ,, give nothing , achieve nothing ""

its that we could do without ...

lol Chimera i used that tool box line lots of times. however i know to Meany carpenters that cant use there tools properly as well these day. it takes more then a fancy tool box to become a carpenter. (joiner for all the British people here lol) nice to have you here. maybe you can show a few people how to use the right tool properly?

A better route to perform an OP of a gynocious line would be to induce pollen on 1/2 of the individuals in the population and allow these to pollenate the other 1/2 of plants- this eliminates the degree of self-fertilization seen in monoecious/gynoecious hybrid populations developed for hemp-seed production.

A more preferable route, however, would be to OP a line that has not yet been made gynoecious to preserve and maintain the line for future development via standard male:female matings. Clones from this OP grow-out can be collected and subjected to a degree of screening for traits of interest, and the chosen genetic contributor plants can be the basis for a first round of recurrent selection, for the traits of interest, in the gynoecious breeding scheme.

Keep in mind, most gynoecious lines are either 1:1 matings or the result of self fertilization events, and all you are doing with OP is preserving the bottleneck. At that point it's a bit late to be thinking about preservation via OP... those who do this are putting the cart before the horse so to speak- the point of an OP is to preserve alleles for future rounds of selection, so attempting this preservation strategy after a SIGNIFICANT bottleneck, completely misses the whole point of the strategy of preservation.

Ahh, now somebody is finally talking some sense. Thanks Chimera, I was wondering how someone would open pollinate with all females, without a bunch selfed seed, which would all but defeat the purpose of open pollination in the first place.
Still it seems a bit redundant,
I agree.

There are ways round it! the problem you have is how most gynoecious populations if you can call them that are produced at the moment IMO... but that problem is not inclusive to "fem" production...

Results boys, results. Do i hear a side by side comparision in the works???

Once and for all lets everyone have it out and see who places where.

Only if you are scared or anti-american or some quack you should you find your own pool.

So who is down? Cannabis cup too much drama? We can do our own, cant we???

Enlightend people will vote.
