Fertility Sterility
Fertility and sterility in cannabis genetics describe a plant's reproductive capacity—whether it can produce viable pollen and seeds. Fertile plants carry functional male or hermaphroditic flowers capable of pollination, while sterile lines produce no viable gametes. Sterility can result from genetic incompatibility, chromosomal irregularities, or deliberate breeding selections. Breeders often work with both fertile and sterile phenotypes depending on breeding goals: fertile plants enable seed production and genetic crosses, while sterile genetics prevent unwanted pollination in cultivation. Understanding fertility status is critical for seed banking, breeding program planning, and crop isolation strategies.

Breeders deliberately select for sterility in feminized seed lines and some cultivar stabilization work to eliminate male flower development. Conversely, maintaining fertility in breeding stock ensures reliable seed production and genetic diversity for future crosses.
