Landrace Genetics 101

I'd really like to get the "string of pearls" pheno. Both mine looked a lot like lazyfish's. Still 3 more beans to try. What is the significance of buying them a couple years ago?

I think Barneys actually refers to it as a landrace. What is it's actual lineage? I've done a few sativas from ACE and loved them. I find the pure sativas, although maybe not landrace, are a step change from the hybrid world. Does the same hold true for the indicas? or is today's Afghan pretty much the what you get?

Love the thread...

It will be interesting to see when gene mapping really hits the cannabis world. It was a small world even in the 70s and I suspect a lot of hybridization was inadvertently performed. Just think what a single Thai male seed dropped in the open ground in South America would do to the gene pool. You'd have to go back before man to really experience regional plant evolution. It would be pretty cool though if somebody saved some seeds from a bag of Columbus' stash!

I read an article describing just how genetically similar strains of cannabis are. A reasonable difference between hemp and drug cannabis, but even the indica/sativa genetic makeup were quite similar.

There are true indicas to be found, but cause it's really Hindu Kush landrace everything's there. Pakistan Chitral Kush comes to mind when you think about it. Good, hardy strain that starts to be bred into Cali polyhybrid lines to toughen them. I grew it, makes great hash.

Interesting thing is hemp is really indica derivative, PCK is half hemp if you take a look at the genome and has strong CBD marker too, similarly to Lebanese Hash Plant. A lot of landrace lines have big chunk of hemp genome actually and what we define as hemp is really very arbitrary, cause if plant stays under 0,3 THC in flowering it's suddenly different species? It's bullshit.

And it's hard to argue that we inbreed stuff too much. Sure you can get some great expressions that way, but you also make a lot of bad traits dominant and this means they need a lot of attention and it's very hard to make them reliable. I guess it doesn't really matter if you work with clones, but cloning has its limits and downsides and sooner or later the industry is gonna have to develop stable seed lines, cause that's how you grow everything else in this world :tokin2:

Someone have me a "hash plant" fem seed. I wonder if it's the real thing. I hate that cannabis is still so much underground and all you can take is what you get. I don't think the person was lying but I wonder...

I don't quite understand how to read those bars that show the Skunk, CBD, etc. amount. If you look at the horizontal bar, it looks like it's more Skunk than Hemp, but on the vertical bar it's the other way around.
 
No, man. Horizontal one is just what they define as "building blocks" of cannabis. They are most often occuring genotypes. It's actually messy, cause even if they can pinpoint these markers via DNA sequencing they don't really solve egg or the chicken dilemma if you catch my drift. It means the results, vertical bars for analysed samples, point to shared genes (alleles) of given plants. For example do we really want to jump to conclusion that they bred OG to Blackberry, some hemp, skunk and then added a bit of CBD to indica line in a remote village in Pakistan? Sounds unlikely, which means opposite is true, Skunk, Blueberry and OG Kush have roots in Pakistani lines. But as I said most important thing is hemp derives from indica, which they don't even consider landrace as green marker is for sativas only. It's a great tool and community is excited, but they need to step up their game for sure :smokin2:
 
To ME, the designation of hemp... isn't so much about the THC content but, instead, the growing characteristics of the plant and whether or not it is easily used to manufacture the various goods that are made from hemp. Of course I'm no government douche bag, lol, so....

A minor takeaway here is the variability. For both the Baalbak valeey lebanese and Pakistani ChitralKush they show a moderate level of variability.
My guess is that comes from seed banks selling 'close' genetics as the real thing.
 
PCK is from Ace and the other one is from someone else. The thing is that no commercial breeder uses hemp to develop new crosses, usually you see anything but hemp in modern hybrids, so it's rather unlikely. I'd like to see clear indica block though, it seems it's hard for Phylos to establish that.
 
I put mine in a vile and freeze it, but only store for a few months.
 
Use whatever you have to to keep the strain alive and freeze the rest with some rice, vacuum seal it if you can.
