Mutation Selection

Mutation Selection refers to the practice of identifying and propagating spontaneous genetic variations that appear in cannabis cultivars, rather than a terpene itself. Breeders working with this methodology observe phenotypic traits—including altered terpene profiles, morphology, or cannabinoid ratios—that emerge from natural mutations, then selectively breed those specimens to stabilize the trait. This approach has historically produced notable cultivar variants, though mutation rates in cannabis remain relatively low and unpredictable. Documentation of mutation-derived traits within breeding records helps distinguish intentional crosses from accidental genetic shifts. Understanding mutation selection is foundational to modern cultivar development and preservation of rare genetic expressions.

Breeders employ mutation selection to discover novel terpene combinations, cannabinoid profiles, and growth characteristics without directed hybridization. Careful phenotyping and multi-generational stabilization are required to confirm a mutation is heritable and worth preserving within a seed line or clone collection.
