Botrytis Resilience

Botrytis resilience refers to genetic traits that reduce susceptibility to Botrytis cinerea (gray mold), a common fungal pathogen in cannabis cultivation. Plants tagged with botrytis resilience typically exhibit denser trichome coverage, faster leaf transpiration, or tighter bud structure—environmental factors that inhibit mold proliferation rather than antifungal compounds. This classification is primarily relevant to indoor and high-humidity growing environments where gray mold poses significant crop loss risk. Botrytis resilience is a breeding goal rather than an aroma descriptor, though breeders often correlate it with certain terpene profiles and plant morphology. Lineage records frequently note botrytis-resistant cultivars bred from parent strains originally selected for phenotypic mold resistance.

Breeders working in regulated and humid climates prioritize botrytis resilience as a crop insurance trait, crossing it into commercially viable genetics to reduce fungicide dependency. Cultivars developed with this focus often serve as foundational parents for regional adaptation programs.
