Pathogen Pressure Traits

Pathogen pressure traits refer to heritable characteristics that influence a cannabis plant's susceptibility or resistance to fungal, bacterial, and viral pathogens commonly encountered in cultivation environments. These traits include leaf morphology, stomatal density, cuticle thickness, and metabolite profiles that may affect colonization rates or disease progression. Breeders working in this category often select for phenotypes that show reduced infection rates in high-humidity or contamination-prone settings, though environmental management remains the primary control method. Understanding pathogen pressure traits requires documentation of both genetic markers and phenotypic observation across multiple growing conditions. This family encompasses both active resistance mechanisms and structural features that passively limit pathogen entry or spread.

Plant breeders incorporate pathogen pressure trait selection to develop cultivars better suited to diverse climates and cultivation scales. Combining these traits with other agronomic characteristics requires multi-generational evaluation in controlled and field conditions.
