Mold Mildew Resistance Traits
Mold and mildew resistance traits refer to genetic characteristics that help cannabis plants withstand fungal pathogens, particularly powdery mildew (Erysiphe cichoracearum, Podosphaera macularis) and botrytis (gray mold). These traits are often polygenic, meaning multiple genes contribute to disease suppression rather than immunity. Resistance can be expressed through leaf structure (waxy coating, leaf spacing), terpene profiles, or biochemical defenses. Environmental factors—humidity, airflow, temperature—still significantly impact disease pressure regardless of genetic resistance. Breeders working in humid or indoor cultivation zones increasingly prioritize these traits in lineage development.

Breeders select for mold/mildew resistance to reduce crop loss, lower fungicide inputs, and improve cultivation reliability in challenging climates. Combining resistance traits with desired cannabinoid and terpene profiles requires multi-generational screening in high-humidity test environments.
