Traditional Phenotypes

Traditional phenotypes refer to cannabis plants displaying characteristics that have remained stable across generations within established breeding lines. These phenotypes typically exhibit predictable plant structures, flowering timelines, and terpene profiles that breeders have selected for over multiple cultivation cycles. The term encompasses both indica and sativa expressions that emerge consistently from heirloom or foundational genetics, often tracing back to landrace origins or early commercial breeding efforts. Breeders working with traditional phenotypes value their reliability for stabilized crosses and as genetic anchors when introducing novel traits. Understanding traditional phenotype expression is foundational to cannabis genetics documentation and selective breeding programs.

Traditional phenotypes serve as genetic reference points and parental stock in breeding projects. They provide predictable baseline traits—morphology, flowering duration, terpene expression—that allow breeders to more clearly identify how introduced genetics modify offspring characteristics.
