Gynoecious

Gynoecious cannabis plants produce only female flowers, lacking male reproductive organs or pollen sacs. This trait occurs naturally in some cannabis populations and is distinct from feminized seeds, which are created through breeding or chemical intervention. Gynoecious genetics are relatively rare in wild populations but have been documented in certain landraces and breeding lines. The trait is controlled by chromosomal and genetic factors that suppress male development. Breeders working in this category have occasionally reported gynoecious-leaning phenotypes in selective breeding programs, though consistent stability remains challenging. Understanding gynoecious expression contributes to broader knowledge of cannabis sex determination and plant biology.

Breeders researching sex determination mechanisms sometimes track gynoecious individuals to understand how female-only expression occurs at the genetic level. However, commercial application is limited due to the unpredictability of the trait across generations and the established reliability of feminized seed production methods.
