Micropropagation

Micropropagation refers to in vitro plant propagation techniques used to generate genetically identical cannabis clones from small tissue samples under controlled laboratory conditions. Rather than traditional cutting-based cloning, micropropagation uses hormone-regulated culture media to encourage shoot and root development from meristematic tissue, callus, or leaf segments. This method is commonly employed in commercial breeding programs and genetic preservation efforts because it can produce large numbers of uniform plants from a single donor in a compact space. Micropropagated plants typically exhibit rapid growth cycles and consistent phenotypic expression. The technique requires specialized equipment, sterile protocols, and expertise in plant tissue culture, making it less common in small-scale or home cultivation settings.

Breeders use micropropagation to rapidly multiply elite parental lines, preserve rare or unstable genetics, and generate large cohorts of genetically uniform test subjects for controlled breeding trials. The technique enables accelerated breeding programs by reducing generation time and providing year-round propagation independent of photoperiod.
