Poly Cross
A poly cross (or polyhybrid) refers to a cannabis breeding project involving three or more distinct parent plants or lineages, rather than the typical F1 hybrid (two parents). Breeders working in this category deliberately combine genetic material across multiple established strains to explore novel trait combinations—including terpene profiles, morphology, and cannabinoid expression. Poly crosses are more complex to stabilize than binary crosses, requiring careful phenotype selection across multiple generations. This approach is commonly used when breeders seek to blend specific characteristics from different regional or chemotype backgrounds. Documentation of poly cross parentage can become challenging, as tracking three or more divergent lineages requires detailed record-keeping. The resulting offspring typically display increased genetic diversity compared to F1 or F2 hybrids.

Breeders employ poly crosses to access a wider trait palette and break genetic bottlenecks present in two-parent systems. This method is often used when stabilizing complex phenotypes that require favorable alleles from more than two distinct germplasm sources.
