Strain Fixation
Strain fixation refers to the stabilization of consistent genetic traits across successive generations of cannabis plants through selective breeding. Breeders achieve fixation by repeatedly crossing individuals expressing desired characteristics, eventually reducing genetic variation until traits breed true with high predictability. Fixation is measured on a spectrum—F1 hybrids show heterozygous vigor, while F6+ generations typically demonstrate homozygous stability in target traits. Complete fixation means a strain reliably expresses its phenotype without significant segregation. This concept underpins modern strain development and seed banking practices, enabling reproducible cultivation and preservation of established genetics.

Breeders use fixation metrics to determine breeding readiness and seed stability. A fully fixed strain requires fewer backcrosses to maintain trait expression, reducing time-to-market and ensuring commercial seed reliability across multiple harvests.
