Seed Types

Seed types represent the fundamental reproductive classification system in cannabis breeding, divided primarily between regular seeds (containing both male and female genetics) and feminized seeds (bred to produce exclusively female plants). Regular seeds remain the standard in traditional breeding programs, offering genetic diversity and the ability to identify phenotypic variation essential for developing new cultivars. Feminized seeds, stabilized through various breeding techniques since the 1990s, have become commercially dominant because they eliminate the need for sex identification and culling. Understanding seed type is foundational to cannabis genetics work, as each category carries distinct implications for breeding objectives, preservation strategies, and genetic stability. Breeders working with either type must maintain careful records of parental lineage and germination outc

Breeders select seed type based on breeding goals: regular seeds enable phenotype hunting and backcrossing to preserve recessive traits, while feminized seeds accelerate cultivar stabilization and commercial production timelines. Knowledge of feminization methods (chemical or genetic) influences how breeders evaluate trait stability across generations.
