Seed Viability

Seed viability refers to the capacity of a cannabis seed to germinate and produce a healthy seedling under proper conditions. This trait is determined by seed coat integrity, embryo development, moisture content, and storage environment rather than by terpene profile alone. Breeders and seed producers assess viability through germination testing, visual inspection for damage, and controlled storage protocols. Viable seeds are essential for consistent crop establishment and genetic stability in breeding programs. Environmental factors—temperature fluctuations, excessive humidity, light exposure, and pest damage—directly compromise viability over time. Proper curing, packaging in cool dark conditions, and regular viability testing help preserve seed longevity across generations.

Seed breeders prioritize viability assessment to ensure breeding stock quality and to maintain genetic lines across seasons. Detailed germination records and storage protocols inform parent selection and help predict offspring uniformity in subsequent generations.
