Pathogen Resistance

Pathogen resistance in cannabis refers to the plant's natural capacity to resist or tolerate fungal, bacterial, and viral infections. This trait is polygenic, influenced by multiple genes and environmental factors rather than a single terpene. While terpenes like limonene and pinene are commonly associated with antimicrobial properties in laboratory settings, their direct role in whole-plant pathogen defense remains an area of active breeding research. Breeders prioritize pathogen resistance through selective breeding and genetic screening, particularly for powdery mildew, botrytis, and root pathogens.

Commercial cultivators and breeders actively incorporate pathogen-resistant genetics into breeding programs to reduce crop loss and dependency on fungicides. Lineage records frequently document resistance to specific pathogens, making this trait a key selection criterion in modern breeding, especially for indoor and high-humidity growing environments.
