F1 Hybrid
F1 Hybrid refers to the first filial generation produced by crossing two genetically distinct purebred (homozygous) parent lines. In cannabis breeding, F1 hybrids are created by deliberate crosses between stable inbred or landrace strains, resulting in offspring that express heterozygosity across their genome. This first generation typically exhibits hybrid vigor—increased growth rate, uniformity, and phenotypic expression compared to either parent. F1 seeds do not breed true; planting F1 seeds produces genetically variable F2 offspring, making them unsuitable for commercial seed production without re-crossing the parent lines. Breeders use F1 hybrids as stable commercial products and as the foundation for multi-generational breeding programs.

F1 hybrids are prized in commercial breeding for their predictability, vigor, and phenotypic consistency within a generation. Once F1 parent lines are stabilized, breeders can reliably reproduce identical F1 stock year after year, making them valuable for maintaining stable cultivars for seed sales and breeding partnerships.
