What Are F1, F2 and S1 Seeds?

F1 F2 S1 Seeds

Cannabis cultivation involves a captivating interplay of scientific knowledge, artistic finesse, and the natural environment. As you tend to your cannabis plants, you might become curious about their genetic origins and the intricate patterns woven into their DNA. F1, F2, and S1 seeds represent pivotal stages in this botanical journey, each contributing to the rich tapestry of cannabis diversity. This blog unravels the mysteries encoded in these hybrid seeds – the building blocks that shape the cannabis landscape. From F1 to S1, each seed whispers stories of resilience, adaptation, and botanical wonder!

Understanding Cannabis Genetics

Cannabis is dioecious, meaning it can be female or male, as opposed to monecious, which can produce both male and female flowers. Cannabis seeds are produced when pollen from a male strain pollinates a female strain. A hybrid cannabis is created by cross-pollinating two distinct species of weed strains and cultivating the resultant seed, which generates an entirely new strain of cannabis. The plant that sprouts from the seed is known as a hybrid strain. Cannabis can be pure (Indica or Sativa) or a hybrid of strains (often Indica and Sativa). Hybrid cannabis is designed to produce plants with certain terpenes and cannabinoids. Due to the popularity of cannabis history, more hybrids, such as F1, F2, and S1, are being introduced to the market.

F1 hybrid cannabis seeds

F1 hybrid is also known as Filial 1, or a “first child” plant in layman’s terms. These cannabis seeds result from crossing two pure parent strains, thus providing an unparalleled blend of quality genetics. They are an exceptional choice for beginners and seasoned growers, courtesy of their uniformity and high-yielding potential. Breeders generate this hybrid by crossing the most remarkable specimens from their collections. F1 is a robust, stable hybrid with dominant genes from both parents. They also have some of the same characteristics (terpenes and cannabinoids) as their parent plants, resulting in a unique mix.

Furthermore, F1 hybrids are more disease-resistant, stronger, and have higher survival rates than specimens from a single genetic line. They can be distinguished by observable and phenotypic characteristics inherited from their parents. As a result, gardeners might obtain a fluffy weed with long, separated branches — cannabis with strong or mild terpene profiles. To effectively understand F1 hybrid seeds, you must first understand a few breeding and genetic terminology, including:

  1. Inbred lines

Breeders inbreed cannabis plants to preserve genetics and minimize phenotypic expression. For example, if you cross two unstable plants, the progeny may be pretty diverse, with some plants expressing one set of features and some exhibiting another. If you mate two inbred cannabis plants together, the progeny should be homogenous. To capture desired qualities, the siblings with the most desirable traits must be bred together for generations. This causes the alleles in the cannabis plants to become homozygous. Alleles are responsible for genetics being expressed. Offspring from the same parents can have different allele pairings, meaning each will differ. Homozygous plants have identical allele pairings — for instance, aa or AA. Inbred, stable cannabis plants are homozygous.

  1. Hybrid vigor

F1 hybrids are designed to improve specific qualities, known as hybrid vigor. This process is referred to as heterosis (formerly heterzygosis). When a plant has distinct alleles (aA or Aa), it is more robust, grows quicker, and performs better in general (at least in terms of cultivation). So, while breeders will eventually seek to stabilize hybrids, the primary purpose is to diversify a plant’s genetic composition to promote or improve specific features.

  1. F1 hybrids vs Polyhybrids

An F1 hybrid plant is derived from parents with stable genotypes, meaning both parents are from the same inbred line. These might be heritage or just steady hybrid strains. One of the reasons F1 hybrids are so important is that each seed generates a nearly identical plant. However, if specific breeding methods are followed, this consistency will only be passed down to future generations. F1s are similar because their parents are homozygous, meaning they both provide consistent genetics.

In contrast, a polyhybrid has at least one F1 parent. As a result, they are far less stable and predictable, as the F1 lacks solid genetics. Polyhybrids are ideal for experimentation because of their high genetic variety and ability to display unexpected and desirable features. Alternatively, polyhybrids are not the most reliable technique for extracting desirable features since genetic variability makes it impossible to forecast how plants will end up.

F2 hybrid cannabis seeds

In contrast to F1, F2 represents a second-generation hybrid. F2 weed seeds may be generated manually or by open/self-pollination. These seeds are developed from F1 hybrids. F2 hybrids are not bred the same way as F1 seeds. This process is known as “recombination.” It enables breeders to create a strain that combines all of the features passed down from the first generation. F2 hybrid seeds represent the second degree of branching in a cannabis family tree. They sometimes lose some of the characteristics and vigor that distinguish F1 seeds.

Furthermore, F2 hybrids can only inherit 50% of the traits of their mother or father plants. The remaining 50% of F2’s DNA comprises intermediate characteristics. In contrast to F2 genetics, F1 hybrids resemble their parent strains. The main distinction between breeding F1 and F2 cannabis seeds is that the latter does not result in an entirely new cultivar. Breeders recombine existing features in new and innovative ways. F2 generation seeds are only one of the greatest options for most growers. F1 hybrids are more stable than F2 generation strains, which are prone to recombination.

S1 hybrid cannabis seeds

S1 is another kind of cannabis seed. The “S” in the name refers to “self” or “selfed,” implying that the seeds will be self-generated. They do not require male plants to pollinate. Instead, the female plant is inverted so that it may catch pollen. This pollen is subsequently utilized to fertilize the mother strain or a clone of the mother, resulting in S1 hybrids. Males may also be selfed, but the technique is complicated and needs expertise and attention, even among the most experienced growers.

If you’re a newbie, start with autoflower seeds, available in our online store. To create S1 seeds, breeders must take a cutting from a female mother plant and change it into a male plant, which can occur when the plant is subjected to substantial stress, such as silver thiosulphate. This enables the S1 genetics to undergo reversion within a few weeks. Once completed, the pollen generated by the clone plant is utilized to pollinate the original cannabis plant.

An Overview of F3 Seeds

This third generation marks the beginning of stability (but not the end). Plants with AA genetics should not be employed since they only contribute dominant genes, excluding recessive ones. Instead, an Aa and aa should be bred together. Their offspring will then display 50% Aa and 50% aa, considerably closer to what breeders desire. If you breed two Aas together, you’re essentially repeating the process of mating two F1s together, resulting in a majority of AA progeny. That is why you must introduce a cannabis plant with all recessive genes.

In reality, you can’t “see” exactly which genes the cannabis plants have, but you can see the qualities they display and draw conclusions from that. If you want short plants with high yields, breed the plants that exhibit these features and eliminate the remainder. Three generations are not the conclusion of the stabilization process. If you want to develop a genuinely stable strain, you can continue crossing for many more generations (for example, F4s and F5s).

What is Genetic Backcrossing?

Backcrossing adds a desired trait or eliminates an undesirable trait from a strain. Say you like a cannabis plant because it produces a lot of cannabinoids but isn’t very insect-resistant. In this situation, it can be bred with another pest-resistant plant. If all goes well, the resulting F1s will have higher pest resistance but lower cannabinoid output. To prevent this, backcross this F1 with a clone of the parent with high cannabinoid production; the progeny will produce more cannabinoids and be more resistant to cannabis pests. In fact, it takes several generations to maximize and stabilize these features. Ultimately, backcrossing is an essential breeding strategy, allowing breeders to accurately introduce and remove specific characteristics.

What Hybrid Strain Seed Should You Pick?

You should select the most stable seed, which is one with trustworthy genetics that you know precisely what you’ll receive when you plant it, such as an F1, F2, S1, or BX. If you want to breed cannabis yourself, it all depends on the strains you want to produce and if you want to experiment with cross-pollination. Regardless, you should understand how each type of cannabis strain is developed and its genetic background so that you know precisely what you’re growing.
