Polyploidy Triploid Tetraploid
Polyploidy refers to plants carrying more than two complete sets of chromosomes. Cannabis breeders distinguish between diploids (2n, standard), triploids (3n), and tetraploids (4n). Triploids—often sterile or low-fertility—are sometimes pursued for seedless flower production, though fertility outcomes vary unpredictably. Tetraploids exhibit larger cells, thicker leaves, and altered growth patterns; lineage records frequently report increased vigor in some crosses but reduced yield in others. Both represent niche breeding categories requiring specialized cytogenetic knowledge and careful phenotype screening.

Breeders working in polyploidy use chromosome doubling (colchicine treatment) to create tetraploids from elite diploid parents, or cross diploids with tetraploids to generate triploids. Success depends on compatibility testing and multi-generation evaluation, as ploidy shifts affect cannabinoid expression, terpene profiles, and structural traits unpredictably.
