Biodiversity Selection

Biodiversity Selection refers to breeding practices that prioritize genetic diversity within cannabis cultivars or across a breeding program. Rather than selecting for narrow trait expression, breeders working in this category maintain multiple phenotypes, genotypes, or landrace characteristics within a single line or population. This approach contrasts with high-intensity stabilization breeding, which seeks uniformity. Biodiversity Selection is often employed when preserving heirloom genetics, developing resilience to environmental stressors, or maintaining adaptive capacity in breeding stock. Seed companies and heritage-focused breeders frequently document biodiversity-selected lines to reflect their genetic range rather than claiming phenotypic uniformity.

Breeders use biodiversity selection to create genetic insurance—populations with varied expression retain adaptability to changing cultivation conditions and pest pressures. This strategy is particularly relevant in preservation breeding, open-pollination programs, and stabilization of complex hybrid lines where trait consistency is intentionally secondary to genetic richness.
