Line Fixing
Line fixing refers to the breeding practice of stabilizing consistent genetic traits across successive generations of cannabis cultivars. Breeders select parent plants exhibiting desired characteristics—morphology, terpene profiles, flowering time, or yield potential—and repeatedly cross offspring back to these parents or to each other to lock in homozygous alleles. This multi-generational process typically requires 6–8+ generations of controlled pollination and selection before a line is considered stable enough for commercial seed release. Line-fixed strains are foundational to modern breeding programs, offering predictable phenotypes that enable further hybridization or trait isolation.

Line fixing is essential for breeders developing stable seed stock and creating reliable parent material for F1 hybrids. Once a line is fixed, breeders can confidently use it as a foundation for cross-breeding projects, knowing offspring will express consistent traits rather than segregating widely.
