Head smut, one of the most devastating diseases in maize, causes severe yield losses worldwide. Resistance to head smut has been proven to be a quantitative inherited trait. In our previous study, a major resistance quantitative trait locus (named qHSR1) was detected on maize chromosome 2 (bin 2.09), and a number of molecular markers have been developed in(More)
Head smut is a soil-borne systemic maize disease caused by the causal pathogen Sporisorium reiliana. ZmWAK is the gene within the major QTL qHSR1 conferring resistance to head smut disease. ZmWAK has been transferred by marker-assisted backcrossing into elite inbred lines with high-yield potential but susceptible to head smut. The converted inbred lines,(More)
