Seed Testing Protocols

Seed testing protocols are standardized procedures used by breeders and seed banks to assess viability, germination rates, genetic stability, and pathogen presence in cannabis seed stocks. These protocols typically include viability tests (tetrazolium staining, x-ray imaging), germination trials under controlled conditions, and screening for common fungal or bacterial contaminants. Proper testing ensures reliable breeding work and helps maintain consistent phenotypic expression across generations. Documentation of test results creates a foundation for selective breeding programs and supports traceability in regulated markets. Testing protocols vary by breeding operation scale and regulatory requirements, but best practices emphasize controlled environments and standardized methodology.

Breeders rely on seed testing data to identify which lines produce genetically uniform offspring and which stocks warrant further selection work. High germination rates and low pathogen loads indicate seed quality suitable for establishing stable breeding populations or commercial seed production runs.
