Resilience Mold Resistance

Mold resistance is a resilience classification tracking cannabis cultivars selected for reduced susceptibility to fungal pathogens, particularly Botrytis cinerea (grey mold) and powdery mildew. This trait is determined by plant morphology, terpene profiles, and genetic predisposition rather than a single locus. Breeding programs document mold-resistant phenotypes through controlled environment testing and multi-season field observation. Environmental factors—humidity, airflow, canopy density—significantly influence expression, making this a conditional rather than absolute trait. Lineage records frequently report mold resistance emerging from Southeast Asian and Central Asian landraces adapted to humid climates.

Breeders working in outdoor and greenhouse cultivation prioritize mold-resistant genetics to reduce crop loss and fungicide dependency. Selection for this trait often requires multi-generational testing across diverse humidity and temperature conditions to establish stable lineage records.
