Genetic Mutation

Genetic mutations in cannabis refer to spontaneous or induced changes in plant DNA that produce phenotypic traits not present in parent genetics. These alterations can affect plant structure, flowering time, cannabinoid production, terpene profiles, or growth patterns. Mutations may occur naturally during seed development or be deliberately induced through breeding selection or environmental stress. Some historically significant cannabis varieties originated from single mutations that breeders then stabilized across generations. Understanding mutations is central to modern cannabis breeding, as desirable traits—from compact growth to unique flavor compounds—often trace back to identifiable genetic changes. Documentation of these events remains crucial for maintaining accurate lineage records in the cannabis breeding community.

Breeders actively screen for and stabilize beneficial mutations to develop novel cultivars. Deliberate mutation induction through selective pressure or chemical treatment has been used in some breeding programs, though most commercial work relies on natural variation and phenotypic selection.
