Genotyping Methods

Genotyping methods are laboratory techniques used to identify the genetic makeup of cannabis plants at the DNA level. These approaches allow breeders and researchers to distinguish between individual plants, confirm parentage, and track genetic markers associated with desired traits such as cannabinoid production, terpene profiles, or disease resistance. Common methods include microsatellite analysis (SSR), SNP genotyping, and whole-genome sequencing, each offering different resolution and cost trade-offs. Genotyping has become increasingly important in regulated breeding programs where seed certification, genetic purity, and documented lineage are required. Understanding a plant's genotype helps breeders make informed selection decisions and maintain transparent records of strain development.

Professional breeders use genotyping to verify genetic diversity, avoid accidental inbreeding, and authenticate parent plants before crossing. Genotypic data also supports seed banks and licensed facilities in meeting regulatory documentation standards and ensuring reproducibility across generations.
