Cbd Dominant Markers

CBD-dominant markers refer to genetic indicators that breeders use to identify and select cannabis plants expressing higher cannabidiol (CBD) levels relative to THC. These markers are found across various strain lineages, particularly those descended from high-CBD cultivars like Charlotte's Web, Cannatonic, and ACDC. The presence of CBD-dominant markers is determined by allelic variation in genes governing cannabinoid synthase enzymes, particularly CBDA synthase activity. Breeders working in this category rely on both phenotypic observation (cannabinoid testing) and increasingly on genotypic screening to isolate these traits. Understanding CBD-dominant genetics is central to developing cultivars for industrial hemp production, breeding projects targeting specific cannabinoid ratios, and preservation of non-intoxicating chemotypes.

Breeders employ CBD-dominant markers to stabilize high-CBD expression across generations, create consistent 1:1 or CBD-majority ratios, and outcross these traits into established flavor or plant-structure lineages. Selection pressure on these markers has enabled the commercial development of diverse CBD-rich cultivars suited to regulated markets.
