Fusarium graminearum Schwabe, the conidial form of Gibberella zeae, is the causal fungal pathogen responsible for Gibberella stalk rot of maize. Using a BC1F1 backcross mapping population derived from a cross between ‘1145’ (donor parent, completely resistant) and ‘Y331’ (recurrent parent, highly susceptible), two quantitative trait loci (QTLs), qRfg1 and qRfg2, conferring resistance to Gibberella stalk rot have been detected. The major QTL qRfg1 was further conWrmed in the double haploid, F2, BC2F1, and BC3F1 populations. Within a qRfg1 conWdence interval, single/low-copy bacterial artiWcial chromosome sequences, anchored expressed sequence tags, and insertion/ deletion polymorphisms, were exploited to develop 59 markers to saturate the qRfg1 region.
