What Are Cannabis F1 Hybrids Seeds?

F1 Hybrids: elite cannabis seeds yielding nearly identical plants like clones. Combining best traits of two strains for boosted vigor, uniformity, potency. Grower's dream!

What Are Cannabis F1 Hybrids Seeds?

F1 Hybrids are top-shelf cannabis seeds that will produce plants that are almost entirely identical to one another. They are the closest to clones in seed form. Unlike cannabis clones, which have characteristics from one mother plant, F1 Hybrids inherit the best characteristics of two parent strains, resulting in offspring with enhanced vigor, uniformity, and potency. Everything a grower wants to hear!

What are F1 Hybrids

In genetics lingo, F1 (Filial 1) means the first generation of offspring between two parents. However, for a cannabis strain to be considered an F1 Hybrid, its parent strains have to be unrelated. This means breeders must find two cannabis varieties that do not share similar genes for those specific traits. Traditionally, this was done by finding location-specific “landraces” when explorers travel the world and bring seeds back home to widen the gene pool. 

Nowadays, as landraces become harder and harder to find, breeders have to work at inbreeding varieties to create F1 Hybrids. Also called true-breeding varieties or In-Bred Lines (IBLs), these cannabis cultivars are made for the sole purpose of creating a stable strain that consistently expresses certain desirable traits.

Breeders put a lot of time and dedication into ensuring the stability of the inbred lines they’re working with, typically breeding the strain at least five generations (F5) and sometimes even up to twenty (F20).

Why are F1 Hybrid Seeds Special? 

A true F1 Hybrid can only be produced by crossing two completely unrelated parent strains, such as landraces or the above-mentioned IBLs. F1 Hybrids offer two main benefits – codominance and hybrid vigor.

Codominance means the hybrid should express the dominant traits that it shares with its parents, while hybrid vigor means the resulting offspring should have increased performance (growth rate, yield, stress tolerance, etc.)

This means that a true F1 Hybrid plant will express both the stability of dominant traits of the parents but also bring with this predictability an increased performance called “hybrid vigor” or “heterosis.” You get plants that remain “true” to their parents but are usually better performers. Conversely, strains with a shared genetic line have a higher chance of inheriting recessive traits, which will give you less predictable results but more genetic variety.

Why are Phylos x ILGM Production-Ready Seeds the Future of Cannabis Cultivation?

Through a data-driven and scientific approach, Phylos Bioscience uses biotechnology, known as marker-assisted breeding, to speed up the process of creating IBLs. Remember all the hard work breeders do to stabilize a specific strain? Well, Phylos has the ability to apply scientific techniques to speed up the process. Speeding up their phenohunts and selfing processes, therefore producing stable, efficient genetics.

Jared Reynbery, Sr. Director of Plant Breeding at Phylos, shares:

“It's so rewarding to develop this F1 seed technology that, while considered standard in most other ag industries, is quite groundbreaking in the cannabis industry. I strongly believe that transforming cannabis cultivation away from clonal production and towards seed-based production can lower production costs and labor requirements, increase efficiency, and provide medicinal and recreational users with a top-shelf product without the top shelf prices.”

This technology has been used in agriculture for a while and its benefits are proven. There is a good chance your favorite vegetables are produced using F1 Hybrids! Below, you will find some special recommendations from our team of experts.
