Cytoplasmic Sterility
Cytoplasmic sterility is a genetic condition where plants produce non-viable pollen or are entirely male-sterile due to maternally inherited mutations in the cytoplasm—the cellular material outside the nucleus. In cannabis breeding, this trait is relatively rare but has been documented in certain lineages. Cytoplasmic sterility differs from nuclear male-sterility in that it cannot be reversed by crossing with restorer lines, making it a permanent maternal trait. Breeders occasionally encounter this condition when working with diverse genetic backgrounds or landraces. Understanding cytoplasmic inheritance patterns is important for anyone managing large-scale seed production or preservation programs.

Cytoplasmic sterility can unexpectedly disrupt breeding projects if female plants cannot set seed reliably. Breeders studying this trait may use it to identify maternal lineage contributions or investigate cytoplasmic-nuclear interactions in fertility restoration.
