Bud Rot Susceptibility

Bud rot susceptibility is not an aroma but rather an environmental vulnerability trait that breeders monitor during strain development. Dense flower structures, high moisture retention, and poor airflow pathways within the canopy can create conditions favorable to Botrytis cinerea colonization. Genetics influence bud architecture, calyx-to-leaf ratios, and natural resin production—factors that interact with humidity and ventilation to determine rot resistance. Lineage records frequently report that certain cultivar families show greater predisposition to fungal issues under high-humidity conditions. Breeders working in humid climates often prioritize selecting for open bud structure and lower internal moisture retention when developing regional cultivars.

Breeders assess bud rot susceptibility through grow trials in controlled high-humidity environments, selecting parent plants that produce looser flower density and naturally faster-drying structures. This trait is often crossed into popular genetics to improve stability and shelf life in diverse climate zones.
