Test Cross Selection
Test cross selection is a breeding methodology used to evaluate the true-breeding potential and genetic stability of cannabis lines. Breeders cross a candidate plant with a homozygous recessive line (typically a stable male or female) to reveal hidden recessive alleles in the offspring. This approach helps identify whether desirable traits breed true or depend on heterozygosity. Test crosses are foundational in cannabis genetics work for establishing F1 hybrids with predictable characteristics, validating inbred lines, and understanding trait dominance patterns. The practice is common among seed companies working to stabilize new cultivars before commercial release.

Test crossing accelerates the identification of stable genetics and reduces the number of generations needed to fix desired traits. Breeders rely on this selection method to confirm phenotypic stability and map trait inheritance before committing resources to large-scale seed production.
