Cannabinoid Ratio Expression
Cannabinoid ratio expression describes the quantitative and qualitative distribution of cannabinoids within a plant's chemotype—most commonly the relative proportions of THC, CBD, and minor cannabinoids like CBG, CBN, and CBDV. This classification reflects both genetic potential and environmental factors that influence biosynthetic enzyme activity during flower development. Breeders and researchers use cannabinoid profiling to identify stable lineages and categorize plants along a spectrum from THC-dominant to CBD-dominant to balanced or minor-cannabinoid-rich phenotypes. Understanding ratio expression is central to cannabis taxonomy, as chemotype often remains more consistent across environmental conditions than terpene profiles. Documentation of cannabinoid ratios requires laboratory analysis (HPLC or GC-MS) and is foundational to breeding programs targeting specific cannabinoid target

Breeders select and stabilize cannabinoid ratios through multi-generation crosses, backcrosses, and marker-assisted selection to produce cultivars with predictable chemotypes. Knowing a parent's cannabinoid expression profile helps predict offspring expression patterns and identify which lineages carry recessive CBD-synthesis alleles or THC-dominant genetics.
