Intermated mapping populations are expected to result in high mapping resolution for tightly linked loci. The objectives of our study were to (1) investigate the consequences of constructing linkage maps from intermated populations using mapping methods developed for F(2) populations, (2) compare linkage maps constructed from intermated populations (F(2)Syn3) with maps generated from corresponding F(2) and F(3) base populations, and (3) investigate the advantages of intermated mapping populations for applications in plant breeding programs. We constructed linkage maps for two European flint maize populations (A x B, C x D) by mapping 105 SSR markers in generations F(2) and F(2)Syn3 of population A x B, and 102 SSR markers in generations F(3) and F(2)Syn3 of population C x D. Maps for F(2)Syn3 were constructed with mapping methods for F(2) populations (Map A) as well as with those specifically developed for intermated populations (Map B). Both methods relate map distances to recombination frequencies in a single meiosis and, therefore, did not show a map expansion in F(2)Syn3 compared with maps constructed from the respective F(2) or F(3) base populations. Map A and B differed considerably, presumably because of theoretical shortcomings of Map A. Since loosely linked markers could not unambiguously be mapped in the F(2)Syn3 populations, they may hamper the construction of linkage maps from intermated populations.
