Genetic Marker Screening
Genetic marker screening refers to laboratory techniques breeders and seed banks use to identify specific DNA sequences or molecular indicators within cannabis plants. These markers can help distinguish between phenotypes, verify genetic lineage, detect polyploidy, and assess genetic diversity within breeding populations. Common methods include microsatellite analysis, SNP genotyping, and DNA barcoding. Marker-assisted selection enables breeders to make informed decisions about parent plant selection without waiting for full phenotypic expression. This approach has become increasingly relevant as the cannabis industry professionalizes and breeding programs seek reproducibility and genetic authenticity.

Breeders employ genetic markers to accelerate selection cycles, confirm F1 hybrid vigor, identify rare recessive traits before flowering, and maintain detailed genetic records across generations. Markers also help preserve endangered or rare landraces by documenting genetic identity independent of environmental variation.
