F2 F3 Stability
F2 and F3 stability refers to the phenotypic consistency observed in second and third filial generations of cannabis breeding projects. Breeders working in this category track trait expression—morphology, terpene profiles, flowering time—across multiple generations to identify which characteristics breed true. F2 lines (from selfing or crossing F1 hybrids) often show greater variation than F1, while F3 and beyond typically narrow the phenotypic range. Stability metrics help breeders determine whether a line is approaching homozygosity for desired traits or requires further selection work. This framework is foundational to establishing cultivar consistency and predictability in breeding programs.

Breeders use F2/F3 stability assessments to decide which lines merit continued breeding investment versus culling. Selecting for stable phenotypes across generations is essential for developing true-breeding or IBL (inbred line) cultivars with repeatable characteristics.
