Seed Genetics

Seed genetics refers to the heritable traits and cannabinoid/terpene profiles passed from parent plants to offspring through viable seeds. This foundational concept in cannabis breeding encompasses phenotypic expression, chemotype stability, and the genetic markers that determine plant morphology, growth rate, and secondary metabolite production. Breeders working in seed development track genetic lineages across generations to stabilize desired traits, document parent chemotypes, and maintain breeding records. Understanding seed genetics is essential for creating predictable cultivars, preserving rare genetics, and establishing reproducible growing characteristics. Unlike clones, seed lines introduce genetic diversity and can express variable phenotypes even from the same parents, which is both a challenge and an opportunity for selective breeding programs.

Breeders use seed genetics principles to select parent plants with complementary traits, stabilize chemotypes across generations, and create F1 hybrids with predictable vigor and terpene profiles. Tracking genetic purity and documenting lineage records are critical for maintaining cultivar identity and reproducibility in seed-based breeding programs.
