Cannabinoid Content Classification

Cannabinoid content classification systems categorize cannabis plants based on their dominant cannabinoid profiles—most commonly THC, CBD, or balanced ratios. These classifications emerged from early chromatographic testing and remain central to breeding programs seeking specific chemical outcomes. Historical landrace and heirloom varieties often displayed narrow cannabinoid ranges, while modern breeding has expanded the range of achievable ratios. Classification schemes vary by region and testing lab; no single universal standard exists. Breeders working in this category typically track cannabinoid expression through multiple generations to stabilize desired profiles. Understanding cannabinoid classification is foundational to genetics work, regardless of end-use application.

Breeders select parent plants based on cannabinoid profiles to create stable, predictable offspring. Cannabinoid content is polygenic and influenced by environment, making consistent classification across seeds a core breeding challenge.
