Botrytis Bud Rot Resistance

Botrytis bud rot resistance refers to a plant's genetic capacity to resist infection by Botrytis cinerea, a fungal pathogen that commonly affects dense cannabis flowers in humid environments. Strains exhibiting this trait typically feature tighter, more compact trichome structures or genetic markers associated with reduced susceptibility to fungal colonization. Resistance is not absolute immunity but rather a relative decrease in infection likelihood under standard cultivation conditions. Environmental factors—humidity, air circulation, and temperature—remain critical to disease management regardless of genetic predisposition. Breeders tracking botrytis resistance often cross lineages known to maintain flower integrity in high-moisture settings or select for phenotypes with naturally superior air penetration through bud architecture.

Cultivators and breeders working in humid climates or outdoor environments actively seek botrytis-resistant genetics to reduce crop loss and fungicide dependency. Selection for this trait often involves phenotypic screening under controlled high-humidity stress tests and molecular marker tracking when available.
