Thc Suppression Traits

THC suppression traits refer to genetic factors that result in cannabinoid profiles with minimal or non-detectable THC content, while maintaining other cannabinoid production such as CBD. These traits can emerge through selective breeding for specific chemotypes or through natural genetic variation within cannabis populations. Lineage records frequently report THC suppression occurring in certain CBD-dominant cultivars and hemp-derived genetics. Understanding these traits is essential for breeders working in jurisdictions with THC restrictions or developing cannabinoid-specific cultivars. The mechanisms involve complex interactions between multiple genetic loci controlling cannabinoid synthase enzymes and their precursor pathways.

Breeders leverage THC suppression traits to create compliant cultivars for regulated markets and to stabilize CBD or CBG-dominant lines through targeted crosses with known low-THC genetics. Characterization of these traits helps predict cannabinoid expression across breeding populations and informs selection strategies for multi-generational stability.
