Bud Rot Susceptibility

Bud rot susceptibility refers to a strain's genetic predisposition toward fungal infections, particularly Botrytis cinerea, under high-humidity or poor-airflow conditions. This classification emerges from lineage records and cultivation reports rather than a single genetic marker, as multiple environmental and plant-structure factors contribute to disease pressure. Strains with dense bud architecture, slower flower-to-harvest maturation, or origins from humid growing regions are often tagged as higher-susceptibility varieties. Conversely, genetics selected for loose, airy flower structure and rapid finishing commonly show lower susceptibility profiles. Understanding a strain's documented susceptibility helps breeders strategize environmental controls and select parent plants for disease-resistant breeding programs.

Breeders working in disease-resistance programs prioritize strains with documented low bud rot susceptibility when selecting breeding stock. Crossing low-susceptibility genetics with commercially desirable traits allows developers to build resilience into new cultivars without sacrificing yield or flower quality.
