On this episode of Agrify Live, Agrify’s VP & Head of Horticulture and Customer Success, David Kessler, discusses cannabis genetics, pheno-hunting, and genetic selection, with special guest, Miles Durham. Miles is a grower and genetic expert who is currently working with Greenstone out of Colorado.
Tips about Cannabis Genetics:
It is important to do research: know your breeders, how they formed, who they partnered with, the history, where they breed, and how they breed.
The United States is in the middle of a "genetic renaissance."
Phenotypes are the genetic expression specific to grow and custom to the environment.
Genotypes are traits that stem from DNA or the genetic makeup of the plant.
Pheno-hunting is sifting through seeds to look for traits the grower needs to cultivate.
The more seeds, the higher chance of getting the strain with the phenotypes the breeder wants.
If you top your plant earlier, there is a better chance the plant shows sex organs faster, especially if it is topped and grown in the same environment.
Breeders want females for further production.
Males give information, but they are not equipped for mass production like females are.
The three pillars breeders want flowers to express are trichome saturation (potency), terpene profile, and yield.
Stress tests are vital for mass production (temperature, lifecycle, water). Run the test three times (three generations) so the plant stabilizes and does not herm.
The herm trait is when the plant grows male "balls" or "bananas".
Balls look like two lobster claws coming from the plant.
Bananas look like bananas and produce pollen.
We do not want pollen, that's why we eliminate male flowers!
