These strains will produce balanced and homogenous offspring with the desired specific characteristics time and time again for many generations.
The F2 seeds are unstable meaning the plants grown can show very different qualities, some may be good while others are bad. The F2 seeds can contain all the possibilities of phenotypes from all of the previous lineages of both parents.
A group of identical individual plants that always produce offspring of the same phenotype when intercrossed.
F5 – Perfecting the process
Breeders create stabilized hybrids and then continually interbreed, stabilizing their characteristics from generation to generation.
With a little help, anyone can be a grower. But becoming a breeder is an entirely different ball game.
F1 is the result of crossing 2 separate varieties. The resulting seeds are F1 and they will be stable, meaning the plant qualities should be pretty consistent.
F4 varieties contain even fewer phenotypes, which means that the plants should be nearly identical, with only slight variations in, for example, scent or yield.
The most important characteristics manipulated through cross-breeding are the size of the plant, bud to leaf ratio, yield, taste, effect, and acclimatization to western growing conditions.
As you are probably aware of mendles peas, and the fact that an F2 made from two F1s give…
50% F1 trait for a given attribute.
25% Parent one trait for a given attribute.
25% Parent two traits for a given attribute.

Now, this is the bit that I suppose is the magic of backcrossing, when you breed your F2 back cross with Parent one yet again you get either.
100% F1 trait or you get…
100% Parent one trait.
Mendel found that some physical properties are dominant while others are recessive. The dominant trait is the one that has more chances to manifest itself, and the recessive traits are those properties that are usually hidden in the first generation (F1) hybridization, but appear in the next.
There are two main varieties of Cannabis found in the world: Cannabis sativa and Cannabis indica. Cannabis sativa is a large “pine-tree like” plant with light green foliage. It is indigenous to Mexico, Columbia, Thailand, India, and Africa.
In addition to F1 and F2 seeds, there are also S1 seeds. The “S” in this case refers to “self” or “selfed”, meaning that these seeds will be selfed-generation. They do not need a male plant for pollen but rather, the female plant is reversed so that pollen can be collected. The pollen will then be used to pollinate the mother plant or a clone of the mother to get S1 seeds. Males can be selfed as well, but in both cases it’s a complex process that requires great focus from even the most experienced breeders.
This will result in the hybrid seeds the breeders are after, and they’re known as “F1” seeds, or first generation seeds. F1 seeds will be the most stable of any seeds that follow it in future generations, and those generations will be known as “F2” seeds, “F3” seeds, and so forth as more seeds are made. However, F1 seeds are the most sought after by breeders because they grow about 25 percent faster, and they grow larger and with more vigor that subsequent generations.
Once someone has become a master grower, they can then work towards being a master breeder. While growers are simply taking seeds and growing them into beautiful plants, they are growing something that nature, or someone else, has actually created. However, when one becomes a breeder, they get to truly play god by breeding different strains together, making seeds, and even making their very own strain. In order to do so, one has to first have a good grasp on things science, genetics, and how cannabis plants work to make seeds, to make bud, and how different plants work together.
The terms “F1” “F2” and “S1” are some of the first that beginner breeders will come across. They refer to outbreeding, or producing hybrid seeds, which is the practice of cross-breeding two plants that originally have completely different genetics. In order to do so, two stable parents must be chosen so the pollen from the male can be used to fertilize the female.
Breeding can be even more exciting than growing because it’s a chance to really make your own strain and create something that will highlight your preferences. Breeding can be a complicated matter, however. Start by understanding some of the basic terminology, and what’s needed to create a stable strain, and you’ll be well on your way to your own.
