Seed Morphology

Seed morphology refers to the physical structure and characteristics of cannabis seeds, including size, shape, color patterns, and surface texture. These traits are determined by genetics and maternal plant conditions during seed development, and they serve as observable markers in breeding programs for tracking lineage and stability. Breeders examine seed morphology to assess seed viability, predict offspring vigor, and identify phenotypic consistency across generations. While seed appearance alone cannot reliably predict cannabinoid or terpene profiles, consistent morphology within a line often indicates genetic stability and successful stabilization work.

Seed morphology is a practical selection tool in breeding; stable, uniform seed appearance across a generation suggests a well-fixed line. Breeders document seed traits as part of strain documentation and phenotype hunting protocols to establish baseline characteristics for future crosses and preservation efforts.
