Reproductive Phenology
Reproductive phenology refers to the timing and expression of flowering cycles in cannabis plants—the observable schedule by which a strain moves through pre-flower, pistil emergence, calyx swelling, and seed or resin maturation. This trait is genetically controlled and shaped by photoperiod sensitivity, day-length requirements, and internal circadian factors. Breeders track reproductive phenology to predict harvest windows, stability across generations, and compatibility with cultivation environments. Early-finishing, mid-range, and late-flowering phenotypes are key considerations in strain development, particularly when crossing photoperiodic and photoperiod-insensitive (autoflowering) genetics.

Breeders select for consistent reproductive phenology to ensure predictable crop timing, reduce phenotypic variance in commercial runs, and match flowering duration to regional growing seasons. Mapping this trait across F1 and stabilized lines helps identify dominant and recessive markers controlling flowering speed.
