f1 hybrid cannabis seeds

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.

Breeding cannabis is a complicated art that can be performed in plenty of ways. Here, we describe the common terms surrounding various cannabis genetics and how they came to be. We decided to keep it short and concise, as all the scientific minutiae can be very complex.

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.

BACKCROSSES

Backcrossing refers to taking a hybrid strain and breeding it back with the original parent. For example, a male Chocolope and a female Jack Herer develop an F1 hybrid. When this F1 hybrid is hybridised with the original female Jack Herer, the resulting strain will be coined as BX1. When this BX1 gets backcrossed again with the original female Jack Herer, it will be coined as BX2, and so on. The genetics of the original female strain can be retained by keeping the plant in the vegetative stage as a mother, keeping the cuttings as clones or using tissue culture propagation.

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.

F1 stands for a “first generation hybrid”. When two strains with completely different genotypes breed, for example, a Master Kush with Durban Poison, their offspring will be an F1 hybrid. When this hybrid is bred together with another F1 hybrid from the same batch (a sister or a brother), it creates an F2 hybrid. When this process is repeated, it creates an F3, then F4, and so on. After F5, the plants can be considered as IBL.

True F1 hybrids are produced by controlled pollination which must be repeated each season. The controlled pollination is done by hand in carefully measured batches and given to the receiving plant in a very controlled environment in order to achieve this hybrid cross. This long process is the reason behind the higher prices of F1 hybrid seeds that you see on the market.

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.

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.

A recombination does happen between two corresponding chromosomes and, because there is no un-linkage of alleles, there is just a recombination with its identical copy. Therefore, the traits of the chromosomes stay linked, producing the desired set of traits on the chromosomes and resulting in an F1 hybrid.

This helps to produce a homozygous plant from a heterozygous starting plant. This process creates doubled haploid cells from haploid cells which eliminate the need for genetic recombination.

Today, medical marijuana facilities, Seed banks and Cannabis Breeder all across the country are using this process of creating F1 hybrids that agriculture has used for decades to produce seeds and plants that have ever-growing desired characteristics. Scientists can identify which type of cannabis treats certain diseases and what the properties in the plants are that achieve this.

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.

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.

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.

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.
