What is an F1 Hybrid? Cannabis Genetics Explained. F1 hybrid breeding in genetics is a type of breeding that focuses on the first initial generation of plants or seeds. It is a type of plant breeding that attempts to domesticate plants and change their genetic properties in order to best benefit growing needs. Unlike other genetic breeding traits, this one seeks to give the initial offspring different qualities than the parents.

Once more careful observations were made by Mendel and genetic traits recorded in the pea plants, the Austrian friar was able to use this newfound knowledge to produce pea plants that gave more peas and better quality peas. This concept of Mendelian inheritance is still what fuels modern-day genetic breeding, including F1 hybrid breeding.

While it may be the simplest way, it usually involves removing all male plants from the population, which can still be time-consuming, but there are also other methods of achieving this. While it may be time-consuming, it is still one of the most commonly used methods in agriculture and plant breeding today. To give you an idea,

However, since these plants are being inbred, there are limitations to what they can achieve. Usually, around the tenth generation, the homozygosity of the plants that are being produced reaches a level, usually determined at 90% or above, where they no longer can yield the desired results. This requires a new process which can be done by simply crossing plants with a different population while avoiding self-fertilization.

Our beloved marijuana strains are produced using several different breeding methods. Check out the terminology used to describe the unique genetics of different cannabis varieties.

LANDRACE

Landrace varieties originate from regions where cannabis plants have been growing for a very long time in the wild—centuries, or even millennia. This naturally creates stable, robust genetics that produce a homogeneous offspring. This means that the landrace strains from a particular area will develop very similar growth patterns, appearance, and chemical composition. Hindu Kush or China Yunnan are examples of pure landrace strains.

Poly-hybrids derive from mixing completely different hybrids with each other. For example, Master Kush and Durban Poison produce offspring called F1(A); AK-47 and White Widow produce an offspring called F1(B). When F1(A) and F1(B) have a lovechild, it will be coined as a poly-hybrid.

IBL stands for “inbred line”, meaning that after several generations of hybridising a specific lineage, the strains become almost like a different family of strains. Skunks were hybridised and selected for their very pungent and potent nature, and after many generations, they developed into the Cheese family, which can be called an IBL.

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.

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.

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.

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.

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.
