Male Sterility
Male sterility refers to a genetic or environmental condition where male cannabis plants produce non-viable pollen or fail to develop functional staminate flowers. This trait can arise from nuclear genetic factors, cytoplasmic inheritance, or environmental stress during critical developmental windows. In breeding contexts, male-sterile lines are sometimes maintained through crosses with fertile males or via vegetative propagation. Male sterility differs from female-only or hermaphroditic expressions and is relatively uncommon in commercial cannabis genetics compared to other controlled traits.

Breeders working with male-sterile genetics may use them to control pollination in controlled-environment breeding or to study sex determination mechanisms. Male-sterile plants can serve as maternal lines in hybrid seed production when crossed with viable males, though documentation of fertility restoration remains inconsistent across lineages.
