Botrytis Resilience

Botrytis resilience refers to a cannabis plant's capacity to resist or tolerate gray mold (Botrytis cinerea), a fungal pathogen that thrives in humid conditions and can devastate indoor and outdoor crops. Plants with higher botrytis resilience often display traits such as tighter bud structure, improved air circulation between flowers, lower leaf density around flowering sites, and faster moisture evaporation from the canopy. This trait is particularly valued in breeding programs focused on disease-resistant cultivars, especially for humid climates or high-density cultivation environments. Resilience varies considerably across genetic backgrounds; some lineages show inherent structural or biochemical advantages against fungal pressure. Breeders selecting for botrytis tolerance typically assess parent plants under controlled humidity stress and evaluate offspring for consistent performanc

Breeders incorporate botrytis-resilient genetics into commercial and craft programs to reduce crop loss and minimize fungicide dependency. Combining botrytis tolerance with desired cannabinoid/terpene profiles or yield characteristics remains a key objective in modern cultivar development, particularly for regions with challenging climate conditions.
