F1 F2 Generation Selection
F1 and F2 generation selection refers to the breeding classification system used to track filial generations in cannabis cultivation. F1 (first filial) plants result from crossing two distinct parent lines, typically showing hybrid vigor and uniform phenotypes when both parents are homozygous. F2 (second filial) generation arises from self-pollinating or crossing F1 plants together, introducing genetic segregation and phenotypic variation. This generational framework is fundamental to modern cannabis breeding, allowing cultivators to stabilize traits, establish true-breeding lines, and understand genetic inheritance patterns across populations.

Breeders rely on F1/F2 selection to identify which traits breed true, which segregate, and when to backcross or stabilize genetics. Mapping phenotypic variation in F2 populations helps breeders recognize dominant vs. recessive traits and select parents for subsequent generations.
