Genuine F1 Hybrids are the jewels in the crown of the Royal Queen Seeds catalogue. The cold truth is creating fantastically potent, productive and vigorous growing F1 hybrids is a long term process. Professional breeders invest years of their lives into breeding projects and select cultivars from hundreds if not thousands of cannabis plants.
Time in the grow op will have already given you a keen eye for pheno hunting. Plus you have developed the hands on cannabis tradecraft skill set to succeed.
Although backcrossing is a tried and tested way to stabilise cannabis genetics, excessive backcrossing can cause some issues. By inbreeding plants to such a degree, any recessive genes that produce undesirable traits will also be strengthened and passed down to all plants of subsequent generations.
Ok, so if you are happy with a batch of regular cannabis seeds. Perhaps you want to make use of the males? Well, you can cross cannabis from the same batch. Assuming you are familiar with the strain and cropping from the same pack of seeds you can potentially select a breeding pair to cross.
Breeding cannabis requires quite a lot of space. You need a nursery and propagation area and different rooms for male and female specimens to avoid unwanted cross-pollination. Even more space is needed if you intend to start breeding polyhybrids over multiple generations starting with four inbred cultivars. If you intend to begin this process, you’ll need to learn how to pollinate your flowers in the correct way.
Seeing as you’re considering breeding, you are probably already well aware of this fact, but it’s always worth reiterating: Keep your males away from your females! This is especially important when looking to breed a polyhybrid because of the increased chances of breeding the wrong varieties together.
First off, you’ll need to collect pollen from male plants when the time is right. Pollen is ultimately plant sperm, and is needed to fertilise female flowers to make them produce seeds. When the male pollen sacs have opened, place a sealable bag over the plant and give it a shake.
One way to achieve this is called backcrossing, also known as “BX” within the cannabis breeding lexicon. When breeders are aiming to create a new strain, they select two parent strains with desirable traits. Upon crossing them, the first generation is created. Backcrossing essentially refers to taking a member of this generation back up the family tree to breed it with one of its parent strains. This type of inbreeding helps solidify the presence of one of the parent’s genes as they are bred together repeatedly.
Cloning is a transferable skill and even more essential to cannabis breeders than growers. You need to have a consistently high success rate with cloning as a prerequisite to breeding.
If you have an amazing strain you want to preserve you need to read this blog. Lets talk about breeding your own weed strain.

Just like many strains now have different effects than popular strains from years ago, you could create strains that are better for you than anything available today. You can even take older heirloom strains and create unique strains that no one has ever experienced.
Evolution of the Cannabis Plant Through Selective Breeding
A famous example a local plant that rocked growing world is the “Ruderalis” plant. People might not consider it a landrace since it doesn’t seem to be actively cultivated by local growers, but it is a local plant that’s been mixed into many breeding programs around the world.
Through the slow process of breeding males and looking at the offspring, breeders can identify particular male plants that are great at producing certain traits in their female offspring.
You can see that the first generation (F1) above would produce only red flowers since all the offspring would get at least one copy of the “R” gene. But if you crossed those F1 plants together, you would get about 3 reds to every 1 white since you’d start getting plants that received two copies of the “W” gene.
First off, why make new strains? Because each new strain has the potential to bring something new to the growing world which has never been seen before.
In fact, the environment plays a really big role in how your plants turn out.
