Cbg Dominant Lines

CBG-dominant lines represent cannabis cultivars selectively bred to express cannabigerol (CBG) as a primary cannabinoid, typically at levels of 5–15% or higher. Unlike THC- or CBD-dominant varieties, CBG-dominant genetics remain relatively uncommon in breeding programs, making lineage documentation particularly valuable. Breeders working in this category often trace genetics to Swiss landrace crosses, specific CBD-dominant cultivars, or experimental F1 hybrids engineered for early cannabinoid expression. The aroma profile of CBG-dominant plants commonly features herbal, woody, and slightly peppery notes, though terpene expression varies significantly by parent genetics. These lines are primarily of interest to breeding programs studying cannabinoid ratios, seed companies developing novel phenotypes, and researchers examining minor cannabinoid biochemistry.

Breeders select for CBG dominance through multi-generational phenotyping and backcrossing, since the trait requires stable genetic expression across generations. CBG-dominant lines serve as foundational genetics for exploring cannabinoid diversity and creating novel chemotypes, particularly in jurisdictions where such research is permitted.
