Cannabinoid Genotype

Cannabinoid genotype refers to the genetic blueprint that determines a plant's capacity to produce specific cannabinoids—primary compounds like THC and CBD, as well as minor cannabinoids such as CBG, CBC, and THCV. Unlike phenotype (observable traits), genotype is the underlying hereditary code passed through parent plants and expressed through breeding lineages. Breeders classify cultivars by their cannabinoid genotype to predict and stabilize cannabinoid profiles across generations. This classification system is fundamental to modern cannabis genetics work, allowing breeders to selectively isolate high-CBD, high-THC, or balanced chemotypes. Understanding cannabinoid genotype helps preserve rare cannabinoid-producing traits and supports targeted breeding programs.

Breeders rely on cannabinoid genotype classification to select parent plants for stable cannabinoid expression and to develop new cultivars with predictable chemical profiles. Testing and mapping cannabinoid genotypes across breeding stock enables systematic preservation of desirable chemotypes and informs cross-breeding strategies.
