The Science of Breeding
How To Do An F1 CrossSuppose you have an awesome strain, and you want to make a high CBD version. Here’s the traditional way of doing it. First, you want to make sure your strain doesn’t already produce CBD. You also need to find a male plant from a strain that makes lots of CBD. You can get males by growing a few plants from seeds. Next, you breed these two strains in what’s known as an F1 cross. Let’s draw a Punnett square to diagram how different versions of a single gene are exchanged during an F1 cross. It looks like this:
How To Do An F2 Cross
Identifying High CBD and High THC PlantsAt Delta Leaf we can identify whether a plant contains the Bt allele, the Bd allele, or both. This saves time and money by identifying the plants you want immediately after germination, instead of waiting months to observe the phenotype. We can also identify whether a plant carries the male, or “Y”, chromosome. Testing can be ordered in just a few clicks.
Below is a final summary graphic showing the entire process of breeding a high CBD strain. Thanks for reading and good luck with your breeding! |
