Pure Line Selection
Pure line selection refers to breeding programs that isolate and stabilize a single, genetically uniform lineage through repeated self-pollination or controlled crosses within a closed gene pool. This approach concentrates desirable traits—such as consistent morphology, terpene profiles, or growth characteristics—by eliminating genetic heterozygosity over successive generations. Breeders working in this category typically maintain detailed phenotype records to identify individuals expressing target traits, then propagate only from those selected parents. Pure line selection differs from hybrid vigor strategies and is foundational to developing stable F1 hybrid parents or true-breeding cultivars. The method requires patience: stability often takes 6–10+ generations of controlled reproduction.

Pure line selection is essential for establishing homozygous breeding stock, reducing phenotypic variation in seed batches, and creating consistent parent lines for commercial F1 hybrid production. Breeders use this technique to lock in specific cannabinoid ratios, terpene combinations, or structural traits for reproducible offspring.
