I have two RILs population developing from bi-parental crosses between a common parental line. A genetic map in the first population was constructed using 260 genotypes and 459 polymorphic DArT markers. In the second population, the map was constructed using 805 markers and 303 RILs. Two populations were genotyped via different DArT markers, so we only have 155 common markers between the two populations. Is it possible to build the consensus linkage map of two RIL populations and show the QTL results on the consensus linkage map?
