Cbg Dominant Phenotype

CBG-dominant phenotypes represent cannabis plants bred to express elevated cannabigerol (CBG) levels, often at the expense of THC or CBD accumulation. CBG is a non-intoxicating cannabinoid that serves as a biochemical precursor to other major cannabinoids during plant development. Breeders working in this category typically select for specific genetic markers and enzymatic pathways that favor CBG synthase activity and slow the conversion of CBG to downstream cannabinoids. These phenotypes remain relatively uncommon in commercial cultivation, as most historical breeding has prioritized THC or CBD-dominant chemotypes. Interest in CBG-dominant genetics has grown as researchers examine the cannabinoid's distinct chemical profile and potential applications in cannabis breeding programs.

Plant breeders use CBG-dominant phenotypes as specialized genetic tools for creating novel cannabinoid profiles and studying cannabinoid biochemistry. These lines also serve as potential parents in crosses designed to generate offspring with balanced or unusual cannabinoid ratios.
