Filial Generation
Filial generation (F1, F2, F3, etc.) refers to successive generations produced by crossing parent plants in controlled breeding programs. F1 designates the first filial generation—offspring from two distinct parent lines—while F2, F3, and beyond represent subsequent generations from self-pollination or intercrossing. This classification system helps breeders track genetic segregation, trait stability, and heterozygosity across generations. Understanding filial progression is foundational to cannabis breeding, as it reveals which traits remain stable and which require continued selection. Different generations show varying phenotypic expression depending on whether traits are dominant, recessive, or polygenic.

Breeders use filial generation tracking to stabilize desirable traits and eliminate undesirable ones. F1 hybrids often exhibit hybrid vigor, while F2 and subsequent generations allow breeders to identify and fix genetic combinations through selective breeding toward IBL (inbred line) status.
