F1 Generation
The F1 generation refers to the first filial generation produced from crossing two distinct parent plants, typically pure or stable lines. In cannabis breeding, F1 crosses are foundational to creating hybrid vigor and combining desired traits from both parents. F1 plants exhibit heterozygosity across their genomes, meaning they carry different alleles inherited from each parent. These plants are not true-breeding, so seeds collected from F1 plants will not reliably produce offspring identical to the F1 parent. Breeders value F1 generation plants for predictability and uniformity within that single generation, making them useful for establishing new cultivar frameworks before stabilization work begins.

F1 crosses serve as the essential starting point for most modern cannabis breeding programs. Breeders use F1 generations to evaluate trait expression, identify desirable phenotypes, and plan subsequent generations (F2, backcrosses, or line stabilization) needed to fix traits into stable cultivars.
