Inbreeding
Inbreeding in cannabis refers to crossing plants that share recent common ancestry, typically within 2–3 generations. Breeders deliberately employ inbreeding to fix desirable traits, stabilize phenotypes, and create homozygous lines suitable for seed production. The practice involves measurable genetic costs—reduced vigor, smaller plant size, and lower fertility—known as inbreeding depression. These tradeoffs require careful selection and outcrossing strategies to maintain viability. Understanding inbreeding coefficients and lineage tracking is essential for responsible breeding programs, particularly when developing stable cultivars or preserving rare genetics.

Breeders use controlled inbreeding to concentrate specific traits and create true-breeding lines, but must balance genetic gain against fitness loss. Regular outcrossing or backcrossing to unrelated stock helps mitigate depression while retaining desired characteristics.
