Colchicine Induced Mutation

Colchicine-induced mutation refers to chromosomal changes deliberately triggered in cannabis breeding through colchicine exposure, a compound that disrupts cell division. This technique has been documented in cannabis genetics research to create polyploid plants—those with doubled or multiplied chromosome sets—which can exhibit altered growth patterns and morphology. Breeders working in this category report that colchicine-treated specimens may display larger leaf size, modified branching architecture, and different metabolite profiles compared to diploid (normal chromosome) parents. The process is primarily a breeding tool rather than an aroma or flavor descriptor, though resulting polyploids sometimes show shifted chemical expression. This approach remains relatively uncommon in commercial cannabis breeding due to regulatory complexity and unpredictable trait outcomes.

Colchicine induction is used by research-focused breeders to explore polyploidy as a genetic variation strategy, potentially creating novel plant structures and cannabinoid/terpene expression patterns. The technique allows breeders to accelerate trait discovery without relying solely on traditional hybridization.
