Cbg Dominant Chemotypes

CBG-dominant chemotypes are cannabis cultivars bred to produce cannabigerol as the primary cannabinoid, typically expressing CBG concentrations above 5% while maintaining lower THC and CBD levels. Cannabigerol is the precursor compound from which THC, CBD, and CBC biosynthetically derive, making CBG-dominant genetics valuable for understanding cannabinoid pathway expression. These chemotypes remain relatively uncommon in commercial breeding compared to THC or CBD-dominant varieties, though interest has grown among researchers and specialized breeders. CBG-dominant plants often display distinct terpene profiles and plant morphologies that differ from their THC-heavy counterparts. Lineage records indicate CBG-dominant cultivars frequently emerge from crosses selecting for specific enzymatic expression patterns rather than recessive traits alone.

Breeders working with CBG-dominant chemotypes focus on stabilizing cannabinoid synthase enzyme expression to reliably produce high CBG output across generations. These genetics serve as research tools for studying cannabinoid biosynthesis pathways and as breeding stock for developing novel cannabinoid ratios in hybrid cultivars.
