Tetraploid Selection
Tetraploid selection refers to breeding programs focused on plants with four sets of chromosomes (4n) rather than the typical diploid (2n) state. In cannabis, tetraploid lines are generated through chemical induction—commonly using colchicine—to double chromosome sets, creating polyploid plants. Breeders working in this category report potential traits including larger flower structures, increased cannabinoid density per cell, and altered morphology. Tetraploid breeding remains experimental in cannabis genetics; lineage records and published studies document both enhanced vigor in some lines and reduced fertility in others. This approach sits at the intersection of classical plant breeding and modern polyploidy research.

Tetraploid lines interest breeders exploring novel trait expression and potentially denser resin production. However, reduced seed viability and unpredictable phenotypic outcomes make tetraploid breeding labor-intensive and require careful selection and backcrossing protocols.
