Molecular Testing

Molecular testing encompasses laboratory methods used to identify and analyze cannabis genetics at the DNA level. These techniques include PCR-based marker systems, microsatellite (SSR) analysis, and next-generation sequencing to confirm strain identity, detect genetic parentage, and assess genetic diversity within breeding populations. Breeders and seed companies increasingly employ molecular testing to verify claimed lineages, detect contamination, and document genetic relationships across their catalogs. Unlike morphological or chemotype identification, molecular testing provides objective, reproducible data independent of growing conditions or phenotypic expression. This family of methods has become foundational in formal breeding programs seeking to maintain genetic records and establish intellectual property documentation for proprietary lines.

Breeders use molecular testing to validate parentage claims, confirm F1 hybrid purity, and construct genetic maps of their working collections. Testing also enables early identification of genetic duplicates and guides strategic crossing decisions in multi-generational breeding programs.
