Autoflowering Inheritance

Autoflowering inheritance refers to the genetic trait that enables cannabis plants to transition from vegetative to flowering growth independent of photoperiod, typically controlled by recessive alleles derived from Cannabis ruderalis subspecies. This trait is not a terpene but rather a flowering-time genetic marker frequently studied alongside terpene profiles in breeding programs. Lineage records show autoflowering genetics were introduced to modern cannabis breeding primarily through crosses with ruderalis-derived cultivars beginning in the early 2000s. The inheritance pattern is complex and polygenic, meaning multiple genes contribute to the trait's expression. Breeders working with autoflowering lines often observe shifts in secondary metabolite production, including terpene ratios, compared to photoperiod-dependent parents. Understanding autoflowering inheritance is essential for b

Breeders use autoflowering inheritance to develop cultivars with reduced flowering timelines and independence from light cycles, enabling year-round cultivation in varied climates. Stacking autoflowering traits with desirable terpene profiles and cannabinoid compositions requires multiple generations of selection and phenotypic evaluation to achieve stable expression.
