Disease Susceptibility Markers

Disease susceptibility markers are genetic indicators that influence a cannabis plant's vulnerability to pathogens, pests, and environmental stressors. These markers help breeders identify plants with inherent resistance or weakness to common fungal infections, mold, mites, and powdery mildew. Understanding these traits requires analysis of plant immune-response genes and phenotypic observation across growing cycles. Breeders working in this category often cross plants showing resilience markers with commercially desirable strains to strengthen overall crop robustness. Susceptibility tracking is particularly relevant in humid climates and indoor cultivation where pathogen pressure is high. Documentation of these traits supports breeding programs focused on durability and reduced cultivation risk.

Breeders use disease susceptibility markers to select parent plants for crosses aimed at improving crop resilience without relying on chemical interventions. Tracking these genetic indicators across generations helps establish lines with consistent resistance profiles, reducing losses to botrytis, powdery mildew, and spider mites.
