Overview of the genomic study and disease resistance breeding using the blast resistant mutant SA0169. Left panel is the flowchart of genomic study in SA0169. The procedure of combining the progeny test and QTL-seq accelerated the mapping process of the blast resistance associated regions in SA0169. Right panel is the steps of breeding resistant lines, which included the selection of a bacterial blight resistant line as the recurrent parent, and the establishment of NILs through MABC with the mapping results. The developed lines can be used as disease resistance donors for BL and BB, and are ready to be released to farmers. This study provides an example for the combination of a genomic study on a SA induced mutant and breeding for disease resistance. BL, blast; BB, bacterial blight; SA, sodium azide; NILs, near isogenic lines; MABC, marker-assisted backcrossing
