Volatile Organic Compound

Volatile Organic Compounds (VOCs) are organic chemicals that evaporate readily at room temperature, forming the aromatic profiles observed in cannabis and other plants. In cannabis genetics, VOCs encompass terpenes, esters, alcohols, and other molecular constituents that contribute to plant aroma and flavor characteristics. Breeders and researchers measure VOC profiles to document strain-specific chemical fingerprints and track inheritance patterns across generations. VOC analysis via gas chromatography or mass spectrometry provides objective data on cannabinoid and terpene diversity within breeding populations. Understanding VOC composition helps geneticists identify marker compounds for strain differentiation and phenotype stabilization.

Cannabis breeders routinely analyze VOC profiles to select parent plants with desired aromatic traits and to verify genetic stability in F1 and stabilized lines. VOC profiling serves as a tool for documenting novel chemotypes and informing crosses designed to preserve or combine specific aromatic lineages.
