Fertility Mutation

Fertility mutations in cannabis refer to genetic alterations that affect reproductive capacity, pollen viability, and seed production. These mutations can occur naturally or be induced through breeding, resulting in plants with altered flowering patterns, reduced fertility, or complete sterility. Some mutations cause hermaphroditism, where plants develop both male and female organs, while others suppress male flower production entirely. Breeders working in this category often study fertility mutations to understand sex determination mechanisms and develop stable female-only populations. These genetic variations are central to understanding cannabis breeding biology and the development of photoperiod-dependent and autoflowering lines.

Breeders leverage fertility mutations to create female-dominant populations, develop stable seed-producing lines, and understand underlying genetic controls of sex expression. Studying these mutations has been instrumental in refining modern breeding techniques and selecting for predictable reproductive behaviors in both feminized and regular seed production.
