Chromosomal Irregularity
Chromosomal irregularity in cannabis refers to deviations from the standard diploid (2n) chromosome count, including polyploidy (triploidy, tetraploidy) and aneuploidy. These conditions arise naturally through mutation or are induced deliberately by breeders using colchicine treatment or other methods. Polyploid plants often exhibit larger leaves, thicker stems, and increased secondary metabolite production, making them subjects of active breeding research. However, polyploid lines frequently show reduced fertility and altered growth patterns compared to standard diploid cultivars. Understanding chromosomal structure remains foundational to cannabis breeding programs exploring vigor, yield stability, and trait expression.

Breeders deliberately induce polyploidy to explore novel phenotypes, increased biomass, and enhanced terpene/cannabinoid profiles. Triploidy and tetraploidy lines are maintained as research populations, though sterility and growth irregularities typically limit commercial viability.
