Pure Line Selection
Pure line selection is a foundational breeding technique in which cultivators repeatedly self-pollinate or cross-pollinate plants exhibiting desired traits—such as specific terpene profiles, morphology, or cannabinoid ratios—across multiple generations to stabilize those characteristics. Over successive generations (typically 6–10+), genetic variation decreases and target traits become increasingly uniform and heritable. This method differs from hybrid crossing in that it aims for genetic consistency rather than heterosis. Pure lines form the basis for many modern cannabis cultivars and are essential for establishing stable, reproducible genetics in commercial breeding programs.

Breeders use pure line selection to develop stable parent stock for seed production, reduce phenotypic variance in crops, and reliably pass on sought-after aromatic, structural, or cannabinoid profiles to offspring. This technique is particularly important in regulated markets where consistency and traceability are regulatory requirements.
