Linkage Groups
Linkage groups are sets of genes located on the same chromosome that tend to be inherited together during reproduction. In cannabis breeding, understanding linkage groups helps predictably combine desired traits—such as resin production, plant structure, or terpene profiles—across generations. Breeders map linkage groups to identify which traits consistently co-segregate and which may separate during crossing. This knowledge accelerates selective breeding by reducing the need to isolate desirable trait combinations through trial and error. Cannabis has nine chromosome pairs, and researchers continue documenting which agronomic and morphological markers cluster together on each.

Breeders leverage linkage group data to design crosses that preserve trait bundles—for example, keeping a high-CBD allele linked with desired flowering time. Predictive breeding using linkage maps reduces generations needed to fix multiple traits in a new cultivar line.
