Inbreeding
Inbreeding in cannabis refers to selective crossing between closely related plants—typically parent-to-offspring, sibling-to-sibling, or repeated backcrossing to a single parent. Breeders intentionally employ inbreeding to stabilize desired traits, concentrate recessive alleles, and fix characteristics across generations. Extended inbreeding can narrow genetic diversity within a line, increasing homozygosity and phenotypic uniformity. This practice is foundational to creating stable, true-breeding cultivars, though it requires careful management to avoid fitness penalties. Inbreeding intensity is measured through coefficients of relationship and is documented in formal breeding records and pedigree analysis.

Breeders use controlled inbreeding—often through F2, F3, and backcross generations—to isolate and lock in specific traits like flower morphology, terpene profiles, or growth patterns. The technique is essential for variety stabilization and IBL (inbred line) development, though progeny vigor must be monitored across generations.
