Open Pollinated Populations
Open Pollinated Populations (OPPs) are cannabis plant groups maintained through uncontrolled, random pollination rather than deliberate cross-breeding. These populations represent working gene pools where genetic diversity is preserved across generations, with offspring expressing variable phenotypes. Historically common in traditional breeding regions, OPPs retain high heterozygosity and can produce unique recombinant traits. Modern breeders sometimes maintain OPP reserves to access broad genetic variation or recover heritage genetics. OPPs differ fundamentally from stabilized lines or F1 hybrids in their genetic structure and breeding predictability.

Breeders working with OPPs use them as source populations for trait discovery and selection pressure experiments. These populations are valuable for researchers studying natural genetic segregation and for maintaining genetic archives when controlled crossing is not feasible.
