Cbd Thc Ratio

CBD-to-THC ratio refers to the relative concentrations of cannabidiol and tetrahydrocannabinol in a cannabis plant or final product, expressed as a mathematical proportion (e.g., 1:1, 2:1, or high-CBD:low-THC). This ratio is determined by plant genetics, particularly the expression of synthase enzymes that convert cannabinoid precursors into either CBDA or THCA during biosynthesis. Lineage records frequently report specific ratios as breeding targets, with documented genetics like Charlotte's Web and Acdc gaining recognition in breeding circles for stable, reproducible CBD-dominant profiles. Breeders working in this category treat ratio consistency as a primary selection criterion across generations, requiring robust testing infrastructure to verify cannabinoid expression.

CBD-to-THC ratio is a quantifiable, heritable trait controlled by multiple genetic loci, making it a central focus in modern breeding programs seeking to develop stable chemotypes. Breeders backcross and select plants with consistent ratios to establish true-breeding lines, and ratio stability across environmental conditions is a key marker of genetic stability.
