Seed Dormancy Traits

Seed dormancy traits refer to genetic mechanisms that delay germination until environmental conditions are optimal for seedling survival. These traits involve physiological and biochemical processes controlled by seed coat permeability, hormone balance, and developmental maturity. In cannabis breeding, dormancy patterns vary significantly across accessions and landraces, with some seeds germinating immediately while others require specific temperature fluctuations or aging periods. Understanding dormancy inheritance helps breeders manage seed viability in storage, predict germination timing, and preserve genetic stability across generations. Dormancy is particularly relevant in breeding programs working with heirloom or wild-origin genetics, where variable germination windows may reflect adaptation to specific growing seasons.

Breeders select for dormancy traits to improve seed shelf-life, ensure synchronized germination in production settings, and maintain genetic integrity during long-term preservation. Controlling dormancy characteristics is essential for standardizing seed behavior in commercial and research cultivation contexts.
