Selection Pressure
Selection pressure describes the intentional cultivation practice where breeders consistently choose plants exhibiting specific traits—phenotypes, cannabinoid profiles, terpene expressions, or structural characteristics—for reproduction across successive generations. This foundational breeding methodology gradually concentrates desired genetic expression while reducing unwanted traits in a population. Selection pressure operates across both sexual and asexual propagation, though mechanisms differ: sexual reproduction allows trait sorting across seed lots, while cloning maintains exact phenotypic copies. Breeders applying selection pressure typically work across 3-7+ generations to establish stable trait expression, with intensity varying based on trait heritability and breeding goals. Modern lineages like Kush, Haze, and OG families emerged through decades of directional selection pressu

Understanding selection pressure is essential for breeders designing stable cultivars and stabilized F1 hybrids. Deliberate selection pressure allows reproducible trait concentration without relying solely on backcrossing or inbreeding, making it central to both commercial and research breeding programs.
