Male Sterility
Male sterility is a genetic trait where cannabis plants produce non-viable pollen or fail to produce pollen altogether, despite developing male flowers. This condition occurs naturally in some plant populations and can be induced through selective breeding or environmental stress. In cannabis cultivation and breeding contexts, male-sterile plants are often studied for their potential to prevent unwanted pollination in controlled environments. The trait is sometimes associated with cytoplasmic or nuclear genetic factors that disrupt pollen development. Understanding male sterility is relevant to seed production management and breeding program design, particularly for those working with hybrid vigor or controlled crossing protocols.

Breeders use male-sterile genetics to prevent accidental pollination in mother plant stock and to maintain seedless flower production in commercial operations. Male-sterile lines can simplify breeding protocols by eliminating the need for manual flower removal or environmental segregation of males.
