Seed Viability Germination

Seed viability and germination refer to the genetic and physiological capacity of cannabis seeds to sprout and establish healthy seedlings. Seed viability is determined by factors including seed maturity at harvest, storage conditions, and genetic robustness of the parent line, while germination rate reflects the percentage of seeds that successfully initiate root emergence under proper moisture, temperature, and oxygen conditions. Breeders and cultivators assess viability through standard germination tests—typically counting emerged radicles within 7–10 days—to evaluate seed lot quality and parent line reliability. Proper storage in cool, dry, dark conditions significantly extends viability windows. Understanding these traits is foundational for seed banking, breeding program maintenance, and commercial seed production.

Breeders prioritize seed viability and germination rates as baseline quality metrics when evaluating parent lines and F1 crosses. Consistent germination performance is essential for commercial seed production, genetic preservation efforts, and maintaining breeding stock integrity across generations.
