Polyploid

Polyploidy refers to cannabis plants with more than two complete sets of chromosomes, a condition that can occur naturally or be induced through breeding techniques. While diploid cannabis (two chromosome sets) is standard, polyploid specimens—typically triploid or tetraploid—sometimes exhibit altered morphology, vigor, or secondary metabolite profiles. Breeders working in this category have historically explored polyploidy as a tool for studying genetic expression and creating sterile hybrids, though the practice remains specialized and uncommon in commercial breeding. Documentation of polyploid effects on cannabinoid or terpene accumulation remains limited in peer-reviewed literature. Polyploid plants often display larger cell size, thicker tissues, and variable fertility, making them primarily of research interest rather than production standard.

Breeders occasionally induce polyploidy using colchicine or other agents to investigate genetic stability, vigor heterosis, or to create seedless F1 hybrids. Polyploid exploration remains a niche breeding discipline, useful for understanding chromosome behavior and metabolite regulation in Cannabis.
