Selection Intensity
Selection intensity refers to the rigor and pressure applied during breeding cycles to isolate desired traits in cannabis genetics. Breeders working in high-intensity selection programs may focus narrowly on specific phenotypes—morphology, terpene profiles, cannabinoid ratios, or flowering time—across multiple generations. This approach can accelerate trait fixation but may also reduce genetic diversity if applied too narrowly. Moderate selection intensity balances trait stabilization with maintenance of viable genetic variation. Understanding selection intensity is foundational to breeding programs, as it directly influences both the speed of trait expression and long-term population health.

Breeders assess selection intensity when designing parent-selection protocols and determining how many generations are needed to stabilize a target phenotype. High intensity selection is often used to develop stable IBL (inbred line) cultivars, while lower intensity allows for broader trait pools in F1 hybrid programs.
