A consensus map for race Ug99 stem rust resistance loci in wheat - 2012 - p. 138

Abstract only

The global effort to identify sources of Ug99 stem rust resistance has generated numerous studies reporting putatively new resistance loci. The purpose of this study was to bring together all available information on stem rust resistance loci and their map locations. The map locations from various sources were combined with our recent association mapping projects involving 608 spring and winter wheat breeding lines from CIMMYT and the IWWIP. This map contains DArT, SSR and SNP markers and thus provides a useful resource for developing the consensus map. Marker loci associated with stem rust resistance were placed on the map and most of them have been mapped in more than one population. Several markers appear to be linked to known Sr genes, whereas other significant markers were located in chromosome regions where no Sr genes were previously reported. This consensus map and related information will be made available on the BGRI web site and periodically updated with all loci associated with Ug99 resistance in wheat.
