Strain Registers

Strain registers are curated genealogical records that document cannabis cultivar lineages, parentage claims, and breeding histories. Major registries—maintained by seed banks, breeding collectives, and research institutions—serve as reference databases for establishing cultivar authenticity and tracking genetic origins across generations. These registers vary in rigor; some employ strict documentation standards while others reflect informal breeder records. For researchers and breeders, strain registers provide critical context about claimed genetics, though conflicting nomenclature and unverified parentage claims remain common in the broader industry. Understanding register limitations helps distinguish between documented lineages and marketing-driven strain names.

Breeders reference strain registers to verify parental genetics, avoid accidental line duplication, and establish credibility within breeding communities. Registers also help track desirable trait combinations and preserve breeding records across multiple generations and geographic regions.
