Clone Selection

Clone selection refers to the practice of identifying and propagating individual plants with desirable traits from a seed population or existing cultivar line. Rather than growing from seed, breeders maintain genetic consistency by taking cuttings from a single mother plant, preserving its specific phenotype across generations. This method became foundational to modern cannabis breeding, allowing cultivators to stabilize desired characteristics like growth pattern, yield structure, and terpene profile. Clone-based lineages form the basis of many named strains, where the original "cut" or "phenotype hunt winner" is preserved and distributed. Understanding clone selection history is essential for tracing strain genetics, as many celebrated lines originated from a single plant's selection rather than planned crosses.

Breeders use clone selection to lock in phenotypes before undertaking controlled crosses, ensuring parent plant stability. This technique also allows preservation of rare or unstable genetics that might otherwise be lost during seed-based propagation.
