In Situ Conservation

In situ conservation refers to the preservation of cannabis genetic material within its original growing environment or traditional cultivation context, rather than in controlled laboratory or seed bank settings. This approach maintains populations in active agricultural cycles, allowing natural adaptation pressures and environmental interactions to shape trait expression over generations. Breeders and researchers employing in situ methods document how landraces and heritage varieties respond to specific regional climates, soils, and seasonal cycles. This strategy differs from ex situ preservation (seed banks, tissue culture) and provides opportunities to study how environmental factors influence cannabinoid and terpene profiles across growing seasons. In situ work is often used to support biodiversity documentation and to establish baseline genetic records before landraces face pressure

Breeders working with landrace genetics frequently rely on in situ conservation networks to access authentic germplasm and observe trait stability under real-world conditions. This method helps establish which phenotypic variations are genetically fixed versus environmentally induced, informing parent selection for controlled breeding programs.
