Microsatellite Markers

Microsatellite markers are short tandem repeats (STRs) of DNA sequences used in cannabis genetic identification and parentage verification. These molecular tools consist of 2–6 base pair motifs repeated multiple times throughout the genome, creating unique patterns across individual plants. In cannabis breeding, microsatellites serve as fingerprints to confirm strain identity, detect genetic duplicates, and establish reliable lineage records. Breeders and researchers employ microsatellite profiling to authenticate seed stocks, prevent seed fraud, and document true breeding relationships in a standardized, science-based manner. Unlike morphological traits alone, microsatellite data remains consistent across environments and growth stages, making it especially valuable for regulated seed markets and conservation efforts.

Breeders use microsatellite panels to verify F1 hybrids, confirm purity in inbred lines, and maintain accurate genealogical records. This molecular approach reduces reliance on visual identification and enables comparison of genetic diversity across breeding populations and regional collections.
