F2 Seed Lines
F2 seed lines represent the second filial generation resulting from crossing two F1 hybrid parents. In cannabis breeding, F2 populations exhibit significantly greater genetic variation than their F1 predecessors, as recessive traits reappear and allelic combinations segregate. These lines are foundational in traditional breeding programs for trait stabilization, phenotype selection, and the development of stable cultivars. F2 work requires larger population sizes to identify desirable phenotypes amid the increased heterogeneity. Breeders commonly use F2 lines to assess heritability of specific characteristics and to establish the genetic architecture of parent material.

F2 lines serve as critical waypoints in multi-generational selection programs. By phenotyping large F2 populations, breeders identify stable trait combinations, create IBL (inbred line) foundations, and determine which genetic contributions from each parent merit retention in subsequent generations.
