F2 Second Filial
The F2 (second filial) generation represents the second round of offspring produced by crossing two F1 individuals. In cannabis breeding, F2 seeds result from selfing or crossing F1 plants, creating genetic segregation where recessive traits can reappear and trait variability increases significantly compared to F1 lines. F2 populations exhibit wider phenotypic ranges, making them valuable for breeders seeking to identify stable line candidates or select for specific recessive expressions. This generation is foundational in establishing stable breeding lines and understanding the genetic architecture of parent germplasm. Breeders commonly use F2 populations to isolate homozygous individuals for desired traits before advancing to F3 or IBL (inbred line) development.

F2 generations are critical for trait selection and genetic mapping in structured breeding programs. Breeders screen large F2 populations to recover rare phenotypes and establish selection pressure for stabilization toward future generations.
