Cannabinoid Terpene Ratios

Cannabinoid-terpene ratios describe the proportional balance between a plant's cannabinoid profile (THC, CBD, CBG, etc.) and its terpenoid composition. This ratio framework is central to modern cannabis genetics research, as both compound classes work through distinct biochemical pathways and accumulate under different environmental and genetic pressures. Breeders and researchers track these ratios to understand cultivar phenotypes and predict chemotype expression across growing conditions. Ratios vary widely—some lines favor high cannabinoid density with sparse terpene expression, while others produce robust aromatic profiles alongside moderate cannabinoid levels. Documentation of cannabinoid-terpene ratios in seed catalogs and lab reports helps establish lineage chemistry and guide breeding toward target profiles.

Breeders select parent plants and stabilize lines based on observed cannabinoid-terpene ratios, as these chemical signatures are heritable and influence both agronomic traits and end-product character. Understanding ratio inheritance helps predictably combine desired cannabinoid potency with specific terpene palettes across generations.
