Pest Tolerance Traits

Pest tolerance traits encompass heritable characteristics that enable cannabis plants to resist or endure damage from arthropods, mites, insects, and other agricultural pests without requiring chemical intervention. These traits include physical barriers (trichome density, leaf texture), biochemical defenses (secondary metabolites), and phenotypic resilience patterns. Breeders working in this category often select parent lines showing reduced pest pressure under field conditions or documented resistance markers. Pest tolerance varies by pest species and environmental context—a plant may show strong resistance to spider mites but remain vulnerable to thrips. Documentation of specific pest responses remains inconsistent across breeding programs due to lack of standardized testing protocols. Understanding these traits supports integrated pest management strategies in both commercial and res

Breeders incorporate pest tolerance traits into selection programs to reduce crop loss and lower reliance on pesticide inputs. Crossing lines with complementary resistance profiles can produce offspring with broader pest resilience while maintaining desired cannabinoid or terpene expression.
