Polyploid Inheritance
Polyploid inheritance refers to cannabis plants carrying more than two complete sets of chromosomes—triploidy (3n), tetraploidy (4n), or higher. While cannabis is diploid (2n) in nature, polyploid specimens occasionally arise through spontaneous chromosomal doubling or deliberate breeding techniques. These plants often display altered morphology, including larger flowers, thicker stems, and modified leaf structures. Polyploidy can reduce fertility and create sterility barriers, which has historically attracted breeder interest for clonal stability. Systematic study of polyploid inheritance remains limited in published cannabis literature, though the trait appears sporadically in breeding programs exploring vigor and novelty traits.

Breeders working with polyploidy pursue it for potential hybrid vigor, altered cannabinoid/terpene expression, and creation of sterile F1 hybrids. The reduced or absent fertility often makes polyploid lines impractical for seed production, limiting commercial application despite theoretical breeding appeal.
