World class Cannabis breeding techniques
Oh yea, cannabis breeding is so much fun. The things you can create from a bit of creativity, an eye for quality and some knowledge is incredible. What sets apart good breeders is good taste.
Dont be a pollen chucker, that’s loser shit for the bin. Real breeding is rare and done by artisans with passion and refinement.
Ok so let’s presume you’ve got that special ability to appreciate cannabis’s finer nuances. Let’s create some outstanding varieties with exceptional traits.
If a strain is stable, let’s say a selectively bred hybrid in f5 stage (we’ll get into that in a second), it may still vary, just much less than say an f1.
The benefit of hybrids is they have great refinement due to already being selectively bred by others. It takes less time creating new strains from pre existing hybrids than creating new strains from pure land race genetics especially wild stock.
If we look at pure strains, namely landrace strains, we have more control over random expressions but we may have to do more work refining them. Landraces offer the best opportunity to create a completely new strain from the ground up.
Mkay so let’s look at the basics of mixing em together. If you cross two unrelated strains together, you gets What’s called an f1 (filial generation 1) or in layman’s terms, first generation of a new hybrid.
If you mix together 2 individuals of the same strain, yes like brother and sister, you get what’s called an f2. F2 is strictly describing a brother/sister cross as this is how we stabilise cannabis. We inbreed it to an extent. Now before you go panicking, a mix of hybridising and inbreeding is exactly the techniques the plant uses in the wild to become adapted to the conditions.
If you crossed two f1’s together that were both different strains to each other, you end up with new f1’s. If you cross two f2’s of the same family (brother/sister) together you’d get F3’s and so on. The f number can only increase with each generation of inbreeding.
When we get to f5 it’s generally considered the most stable you can get without sacrificing too much vigour. As the uniformity increases with each selected inbreed, so the vigour decreases slightly. Around f5 is the balance between consistency and performance. This is why new f1 hybrids often display extreme vigour. Due to what’s know as hybrid vigour.
The next instalment we’ll look at the selection process. How to identify desirable traits and chase them through the generations, as well as valuable unexpected expressions that can show up.
There’s a lot more to breeding cannabis like a connoisseur. Be sure to keep an eye out for the future instalments to find out exactly how.
