Seed Longevity

Seed longevity refers to the viability retention period of cannabis seeds under various storage conditions. Seeds with strong longevity characteristics maintain germination potential over extended timeframes—sometimes years—when stored in cool, dry, dark environments. This trait is influenced by seed coat integrity, oil composition, and genetic factors that affect cellular respiration rates during dormancy. Breeders and seed banks prioritize longevity when preserving genetics, as it directly impacts the feasibility of long-term strain archival and distribution. Understanding seed longevity is essential for both commercial seed production and the maintenance of historical cannabis cultivars.

Breeders working in seed preservation select parent plants that consistently produce seeds with robust coats and lower metabolic activity during storage. Longevity traits are particularly valued in breeding programs focused on genetic conservation and heirloom variety maintenance.
