Thc Cbd Ratio Classification

THC:CBD ratio classification systems categorize cannabis genetics by the proportional relationship between cannabinoids THC (tetrahydrocannabinol) and CBD (cannabidiol). Breeders and researchers use ratio classifications—such as THC-dominant, CBD-dominant, or balanced types—to document chemical profiles across lineages and seed populations. These classifications emerged from cultivation data and lab testing as standardized ways to describe chemotype expression within strain families. Ratio documentation helps breeders track hereditary cannabinoid patterns and select parents for specific breeding objectives. This system is distinct from total cannabinoid content, focusing instead on the relative proportions that define a cultivar's chemical identity.

Breeders use THC:CBD ratio classification to identify parents carrying stable chemotype traits and to predict offspring cannabinoid profiles across generations. Understanding ratio inheritance patterns enables targeted crosses toward desired cannabinoid balances in new cultivar development.
