Gc Ms Genotyping

Gas chromatography-mass spectrometry (GC-MS) genotyping is a laboratory analytical technique used to identify and quantify cannabinoid and terpene profiles at the molecular level. Unlike visual or phenotypic assessment, GC-MS provides precise chemical fingerprinting by separating volatile compounds and measuring their mass-to-charge ratios. Breeders and seed banks employ GC-MS data to verify strain authenticity, document chemical consistency across generations, and establish objective markers for lineage tracking. This methodology became increasingly important as cannabis breeding expanded and the need for reproducible, science-based strain classification grew within the community.

GC-MS genotyping allows breeders to select parent plants with targeted cannabinoid and terpene profiles before crossing, reducing phenotypic variation in offspring. Documentation through GC-MS creates verifiable records that support seed bank claims and help establish stable breeding lines with consistent chemical expression.
