Genetic Female Sterility
Genetic female sterility (GFS) refers to traits that prevent female cannabis plants from producing viable seeds while maintaining normal flower development. This condition can result from chromosomal imbalances, cytoplasmic factors, or specific nuclear-cytoplasmic interactions. Breeders have documented GFS in certain lineages, though the underlying genetic mechanisms remain incompletely characterized. Female-sterile plants still produce normal-looking flowers and cannabinoid profiles, making them valuable for controlled breeding programs. GFS differs from male sterility and should not be confused with feminization techniques used in commercial seed production.

Breeders working in controlled environments sometimes encounter or deliberately select for GFS traits to prevent unwanted pollination and maintain clone-only genetics. Understanding GFS inheritance patterns helps breeding programs predict and manage seed set in multi-generational crosses.
