Homozygous Recessive Line
A homozygous recessive line is a plant population in which all individuals carry two identical recessive alleles (aa) at one or more target loci. This genetic uniformity means offspring will reliably express the recessive trait without segregation across generations. Breeders develop these lines through sustained self-pollination and selection, often taking 6–8+ generations to achieve genetic fixation. Homozygous recessive lines serve as stable genetic resources for understanding trait inheritance, creating predictable F1 hybrids, and preserving specific phenotypic characteristics. They form the foundation of controlled breeding programs and are essential reference materials in cannabis genetics research.

Breeders cross homozygous recessive lines with dominant or heterozygous parents to produce uniform F1 hybrids with known trait expression. These pure lines also enable phenotype mapping, resistance testing, and the development of stable cultivars that breed true across multiple generations.
