Tetraploid Cannabis
Tetraploid cannabis refers to plants with four complete sets of chromosomes (4n), compared to the diploid (2n) baseline found in most cannabis populations. This chromosomal condition occurs naturally at low frequencies but can be induced through breeding techniques such as colchicine treatment or selective crossing. Tetraploid plants often exhibit increased leaf size, thicker stems, and larger flowers, though vigor and fertility vary considerably. Breeders have explored tetraploid lines since the 1970s, with documented instances in both hemp and high-cannabinoid breeding programs. The trait remains relatively uncommon in commercial cultivation due to challenges in stabilization and seed production.

Tetraploid genetics interest breeders exploring novel morphology and potential metabolite expression shifts. However, reduced fertility and polyploidy instability in subsequent generations present significant breeding constraints.
