Line Breeding
Line breeding is a controlled breeding strategy where genetics are concentrated within a selected population over multiple generations. Breeders typically cross related individuals—often parents to offspring or siblings—to stabilize desired traits and increase homozygosity across a genome. This technique differs from outcrossing, where unrelated genetics are introduced. Line breeding records are fundamental to documented cannabis pedigrees, particularly in heirloom and stabilized strain development. While the practice can rapidly fix beneficial alleles, breeders must carefully monitor genetic bottlenecks and maintain population health to avoid inbreeding depression.

Professional cannabis breeders employ line breeding to stabilize phenotypic expression, create true-breeding cultivars, and document maternal or paternal lineage with precision. This approach requires multi-generational commitment and detailed record-keeping to track inheritance patterns and select for consistency in cannabinoid ratios, terpene profiles, and plant morphology.
