Genotype Classification

Genotype classification in cannabis refers to the genetic makeup of a plant, distinct from its observable phenotype. Breeders use genotype classification to categorize plants by their inherited traits—such as cannabinoid ratios, terpene profiles, or growth structure—rather than how those traits express in a specific environment. Understanding genotype is fundamental to predictable breeding programs, as it determines what traits can be reliably passed to offspring. Cannabis genotypes are often documented through lineage records, seed type designation (photoperiod, autoflowering, feminized), and lab testing of cannabinoid/terpene content. This classification system helps breeders select parents for crosses and predict the stability of desired characteristics across generations.

Breeders prioritize genotype classification to establish stable lines and develop F1 hybrids with consistent traits. By selecting plants with documented genotypes, breeders can reduce phenotypic variation and create reproducible cultivars for seed production and commercial cultivation.
