Minnesota Researcher Finds Genetic Difference Between Hemp & Marijuana

They belong to the genus cannabis and they are distinguished by the concentration of the psychoactive drug, which is abundant in marijuana and much less so in hemp. What did you find in this gene? What we did was take advantage of this diversity that exists within the species cannabis to cross a marijuana plant with a hemp plant.

And then we mapped the gene that distinguishes the production of THC versus a related molecule, called CBD, that’s been getting a lot of attention in the press lately. We can trace this down to the fact that marijuana is missing an enzyme that produces this molecule, CBD, so THC dominates in the chemistry of marijuana plants.
