1 To 1 Ratio
The 1:1 ratio designation refers to cannabis cultivars bred to express roughly equal concentrations of THC and CBD. This balanced cannabinoid profile is the result of deliberate crossing programs targeting both major cannabinoids simultaneously, rather than the THC-dominant or CBD-dominant emphasis found in most modern lineages. Breeders working toward 1:1 ratios often employ test crosses and marker-assisted selection to identify parents carrying active CBD-synthesis genes alongside standard THC pathways. The aroma of 1:1 cultivars is not fixed—it varies widely based on terpene content and parent genetics—but the cannabinoid balance itself has become a recognized breeding category in seed banking and genetic documentation.

Breeders pursuing 1:1 genetics use this ratio as a selection criterion to maintain genetic diversity in high-CBD cultivar libraries and to create experimental crosses for novel cannabinoid expressions. Seed programs often isolate and stabilize 1:1 phenotypes across multiple generations to establish this trait as a reliable lineage marker.
