Disease Resistance Mechanisms
Disease resistance mechanisms in cannabis refer to the genetic and physiological traits that enable plants to withstand or limit pathogenic infection—including resistance to powdery mildew, botrytis, root pathogens, and viral agents. Breeders have long observed variation in plant susceptibility across cultivars and landraces, with some lineages demonstrating measurably higher tolerance to common fungal and bacterial pressures. These traits are polygenic in nature, involving both constitutive defenses (present before infection) and inducible responses (activated upon pathogen detection). Understanding the mechanisms—such as stomatal density, cuticle thickness, secondary metabolite profiles, and systemic acquired resistance pathways—has become central to modern breeding selection. Documentation of disease-resistant phenotypes remains limited in peer-reviewed literature, though cultivation

Breeders working in regulated markets increasingly prioritize disease resistance as a stability trait, particularly for indoor and outdoor cultivation in humid climates. Crossing susceptible elite cultivars with resistant landrace material or established resistant lines remains a primary strategy for incorporating these polygenic traits into commercial genetics.
