Seed Vigor Testing

Seed vigor testing encompasses standardized protocols used by breeders and seed banks to assess germination capacity, growth potential, and long-term viability of cannabis seeds. These evaluations measure factors including germination speed, seedling root development, and storability under controlled conditions. Vigor testing differs from simple germination rates by examining the overall robustness of seed performance across multiple growth parameters. Breeders rely on vigor data to identify elite parent stock, ensure batch consistency, and predict field performance before large-scale cultivation. Proper vigor assessment is foundational to maintaining breeding line integrity across generations.

Breeders use vigor testing to qualify seed lots for breeding programs, validate storage methods, and select high-performance phenotypes for preservation. Vigor data directly informs decisions about which genetics merit further breeding work versus culling, and helps predict how seeds will perform in diverse growing environments.
