Ploidy Levels
Ploidy level refers to the number of chromosome sets present in a plant's cells. Cannabis typically exists as a diploid (2n), with two sets of chromosomes, though polyploid forms—triploid (3n) and tetraploid (4n)—occur naturally or through breeding intervention. Ploidy affects plant vigor, cannabinoid/terpene expression, fertility, and overall phenotypic expression. Breeders document ploidy levels because they directly influence breeding outcomes, seed viability, and plant architecture. Understanding ploidy is foundational to modern cannabis genetics work, particularly when stabilizing lines or creating hybrid vigor. Higher ploidy often correlates with larger flowers and altered metabolite profiles, though effects vary widely by genetic background.

Breeders intentionally work with different ploidy levels to induce hybrid vigor, alter cannabinoid/terpene ratios, or create sterile cultivars. Triploid and tetraploid lines are valuable selection tools for studying how chromosome doubling influences secondary metabolite production and plant morphology.
