Seed Viability Testing

Seed viability testing encompasses laboratory and practical methods used to assess whether cannabis seeds are capable of germination and healthy development. These protocols include tetrazolium staining, germination trials, and moisture content analysis—standard practices in seed banking and breeding programs. Viability testing helps breeders confirm seed quality before committing resources to large-scale cultivation, and informs storage recommendations to maintain genetic integrity across generations. Accurate viability data is essential for breeding records, as it directly impacts the reliability of genetic experiments and line maintenance. Testing results typically influence decisions about seed preservation conditions, breeding strategy adjustments, and stock rotation in professional seed libraries.

Breeders rely on viability testing to validate seed lots before crossing, ensure genetic line continuity, and optimize storage protocols. Consistent viability data supports informed decisions about which seeds to use in active breeding programs versus long-term preservation.
