Tetraploid Traits

Tetraploid traits refer to genetic characteristics expressed in cannabis plants with four sets of chromosomes (4n) rather than the typical two sets (2n) found in diploid varieties. Tetraploid cannabis plants are produced through chromosome doubling, typically induced by colchicine treatment or spontaneous mutations. Breeders working in this category report that tetraploid lines often exhibit increased plant vigor, larger flowers, thicker stems, and modified terpene profiles compared to their diploid parents. These polyploid specimens are primarily used in controlled breeding programs to explore novel trait combinations and genetic diversity. Tetraploid breeding remains an experimental category with limited commercial prevalence, as sterility and propagation challenges often accompany the chromosome doubling process.

Breeders employ tetraploid induction as a tool for creating novel hybrid vigor and exploring genetic boundaries in cannabis horticulture. Tetraploid × diploid crosses can produce triploid offspring with distinct morphological and biochemical properties, expanding the genetic toolkit available to cultivators focused on trait expression research.
