Abstract excerpt
This study aimed to improve the restorer line IR 42266-29-3R (A42) for multiple stress tolerance using integrated marker-assisted backcross breeding (MABB) and the doubled haploid (DH) approach. The primary objective was to introduce the abiotic stress tolerant QTL (qDTY1.1 and qHTSF4.1) into the background IR 42266-29-3R, which already harbors three bacterial blight (BB) resistance genes (xa5, xa13, and Xa21)....
