Triploid

Triploid cannabis plants contain three sets of chromosomes (3n) rather than the typical diploid two sets (2n). This chromosome configuration typically arises from crossing diploid plants with tetraploid (4n) plants, or through other polyploidy-inducing methods. Triploids are often sterile or produce non-viable seeds, as the odd chromosome count complicates meiosis and gamete formation. Breeders and researchers have documented triploid cannabis in controlled crosses, though they remain uncommon in standard breeding programs due to propagation challenges.

Triploid sterility interests some breeders as a theoretical route to seedless plant production without chemical gibberellic acid treatment, though the trait's unpredictability and propagation difficulty limit practical adoption. Most commercial seedless breeding focuses on feminized diploids or other established methods rather than triploid development.
