Open Pollinated Varieties
Open pollinated varieties (OPVs) are cannabis populations maintained through natural, uncontrolled pollination rather than deliberate crossing. Seeds from OPV plants will produce offspring with genetic variation, as opposed to the uniform F1 hybrids created by controlled breeding. Historical landrace strains and many traditional cultivars fall into this category, preserving genetic diversity across multiple generations. OPVs remain relevant in breeding programs where breeders value phenotypic range and adaptation to local growing conditions. Modern seed banks occasionally release OPV collections to document genetic heritage and support preservation efforts.

Breeders working with open pollinated varieties typically select desirable phenotypes across multiple generations to stabilize traits, a process distinct from F1 hybrid production. OPVs serve as genetic reservoirs for outcrossing projects and landrace documentation.
