Haploid Lines
Haploid lines are cannabis plants with a single set of chromosomes (n=5) rather than the typical diploid state (2n=10). These rare individuals arise spontaneously or through specialized breeding protocols such as anther culture or chromosome doubling suppression. Haploid lines are not viable for cultivation but serve as critical research and breeding tools, allowing breeders to identify and fix recessive traits in a single generation. Because all genetic material is expressed without masking, haploid derivatives enable rapid trait stabilization and homozygosity. Commercial breeding programs occasionally employ haploid protocols to accelerate inbred line development or map genetic markers.

Breeders working with haploid lines use them to expose hidden recessive alleles and create homozygous doubled-haploid (DH) lines in fewer generations than traditional inbreeding. This technique accelerates variety stabilization and facilitates marker-assisted selection in formal breeding programs.
