Snp Genotyping

SNP genotyping refers to the identification and mapping of single nucleotide polymorphisms (SNPs)—individual nucleotide variations across the cannabis genome. This molecular technique allows breeders and researchers to distinguish genetic differences between plants at the DNA level, creating detailed genetic profiles independent of phenotypic expression. SNP genotyping has become foundational in modern cannabis breeding programs, enabling parentage verification, disease resistance identification, and population diversity assessment. Unlike traditional morphological or chemical analysis, SNP data provides objective, reproducible genetic information that persists regardless of growing conditions. This approach is commonly used in formal breeding registries and seed bank preservation protocols to document genetic authenticity.

Breeders leverage SNP genotyping to confirm true-breeding lines, identify unexpected crosses, and map quantitative trait loci (QTLs) linked to cannabinoid production, terpene profiles, and disease susceptibility. SNP markers accelerate selective breeding cycles by allowing early-stage plant identification before full phenotypic expression.
