The professional term ”F1 Hybrid Seeds” is incorrectly used today in the Cannabis seeds industry. The crossing of two different cannabis strains form a new F1 (“first generation”) hybrid plant. When it comes to weed terminology, nothing is more complicated than the codes used when breeding? F1 genetics are cited as best, but what does it mean?
The professional term ”F1 Hybrid Seeds” is incorrectly used today in the Cannabis seeds industry.
The crossing of two different cannabis strains form a new F1 (“first generation”) hybrid plant. However, all the Cannabis strains that exist in the market today are greatly heterozygous, meaning that any pollination (crossings) between such two different Cannabis strains will produce seeds with increased genetic instability.
Thus, today each individual seed produced in a pollinated plant, even though it’s essentially an F1 hybrid seed, is in principal different than all the other seeds in that same plant.
The fact that all seeds are different from each other in one particular plant means that the propagation of plants from such seeds, even though they originated from the same plant, produces plants with different DNA profiles.
That is why the only method accessible to Cannabis growers today, to maintain identical (“true to type”) offspring of one unique plant (termed a ‘mother plant’), is through cloning (either vegetative propagation or tissue culture).
In contrast, the conventional seeds industry terms an F1 Hybrid seed as a seed developed from the crossing of two distinct 100% homozygous strains – also referred to as “Parental Lines” (a ‘female plant’ and a ‘male plant’). The crossing of these two stable parental lines always produce the same F1 hybrid seeds, which are not only identical to each other, but are always 100% uniform in their DNA profile.
The propagation of seedlings from 100% uniform F1 hybrid seeds will always result in identical plants (“true to type”), thus making redundant the need for cloning of Cannabis and Hemp
F1, F2, S1 – What do They Mean for Your Weed?
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.
What are F1 and F2 cannabis seeds?
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.
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.
What are S1 seeds?
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.
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.
