Tetraploid Breeding
Tetraploid breeding refers to the deliberate cultivation of cannabis plants with four sets of chromosomes (4n) rather than the typical two (2n diploid). This chromosomal doubling, often induced chemically using colchicine or occurring naturally in rare cases, can result in larger flowers, increased biomass, and altered terpene profiles. Breeders working with tetraploids have reported shifts in secondary metabolite production, though stability and fertility present significant challenges. Tetraploid lines are less common in mainstream cannabis breeding due to reduced seed viability and more complex genetics. Research into polyploidy in cannabis remains limited but represents an active frontier in horticultural genetics.

Breeders exploring tetraploid lines seek trait amplification—larger resin glands, denser trichomes, and potentially enhanced cannabinoid or terpene expression. Tetraploid crosses with diploid parents (triploids) often exhibit hybrid vigor but require careful selection for viable offspring.
