Cutting Propagation

Cutting propagation refers to asexual reproduction where a vegetative cutting from a donor plant is rooted to produce a genetically identical clone. This method preserves exact phenotypic traits—cannabinoid profiles, terpene expression, growth patterns—without the genetic variation inherent in seed propagation. Historically, cuttings have been the primary cloning technique in cannabis cultivation due to accessibility and reliability. The donor plant's age, health status, and environmental conditions influence cutting viability and rooting success. Breeders and cultivators use cutting propagation to maintain elite phenotypes across multiple generations and production cycles.

In breeding programs, cutting propagation serves as a stabilization tool, allowing breeders to isolate and multiply desirable phenotypes before formal line selection or seed production. It also enables long-term preservation of parent genetics and facilitates controlled hybridization by maintaining mother plants with known, consistent traits.
