Tetraploidy
Tetraploidy refers to plants with four sets of chromosomes (4n), double the diploid state typical of most cannabis cultivars. This condition arises through spontaneous chromosome doubling or deliberate breeding intervention, and produces notably larger cells, thicker cell walls, and sometimes increased vigor in vegetative growth. Tetraploid cannabis plants often exhibit altered leaf morphology, denser canopy structure, and modified secondary metabolite profiles compared to their diploid parents. Breeders have documented tetraploid lines in both photoperiod and autoflowering backgrounds, though fertility and seed production can be unpredictable due to chromosome pairing complexity during meiosis. The trait remains relatively uncommon in commercial genetics, partly due to propagation challenges and the need for stable, reproducible methodology.

Plant geneticists and specialty breeders use tetraploidy to explore novel phenotypic traits, increase cell size for potentially enhanced resin gland development, and create sterile or reduced-fertility hybrids. Establishing stable tetraploid lines requires chromosome doubling agents (such as colchicine), careful selection, and multiple generations of stabilization—making it a research-intensive un
