Fig. 2. Breeding schemes for integrating SNP genotyping into molecular breeding programs. (A) Marker-assisted backcrossing (MABC) and QTL pyramiding are used to rapidly transfer major genes and QTLs into existing high-yielding varieties, as in the example of rice variety IR64 with different combinations of added QTLs; (B) marker-assisted selection (MAS) can be used during pedigree and bulk selection to eliminate undesirable lines and fix major genes in the breeding populations; and (C) genomic selection uses genome-wide scans to calculate genomic estimated breeding values (GEBVs), which can be combined with selection for major genes and QTLs as fixed effects to improve the model.
