Potency Classification

Potency classification in cannabis genetics refers to categorical systems breeders and cultivators use to describe cannabinoid concentration ranges, primarily THC and CBD levels. These classifications—often labeled as low, moderate, high, or ultra-high—emerged from breeding records and laboratory testing standardization in the late 2000s onward. Potency classification is distinct from aroma itself but frequently correlates with terpene profiles, as certain chemotypes tend toward specific volatile compound combinations. Breeders working in this category track potency inheritance patterns to predict offspring cannabinoid ranges and stability across generations. Understanding potency classification helps document genetic lineages and breeding goals, though actual cannabinoid content varies significantly by cultivation environment, harvest timing, and post-harvest handling.

Breeders select parent plants partly based on potency classification to establish predictable offspring ranges and stabilize cannabinoid expression in new cultivars. Potency classification data informs F1 hybrid design and inbred-line development, enabling targeted crosses for specific market segments or research objectives.
