Pure Line
A pure line refers to a cannabis population maintained through continuous self-fertilization or controlled breeding within a genetically uniform group, resulting in high homozygosity across loci. In breeding contexts, pure lines serve as stable genetic foundations—predictable and repeatable across generations. Breeders working in this category often use pure lines as parental stock to establish consistent F1 hybrids or to isolate and stabilize desired traits. Pure line development requires multiple generations of deliberate selection and inbreeding, typically 6–10+ cycles, to achieve homogeneity. This classification contrasts with outcrossed or hybrid populations, which retain greater genetic heterogeneity. Pure lines are foundational in formal breeding programs, seed banking, and trait stabilization efforts.

Breeders rely on pure lines as reliable parental materials for predictable hybrid production, trait isolation, and establishing commercial baselines. Pure line genetics enable repeatability in seed production and serve as reference genetics for mapping specific traits.
