Host plant resistance offers the best solution for economic management of bacterial blight (BB) of rice. In thepresent study, we have introgressed a wild-rice derived, broad-spectrum BB resistance gene, Xa33 along withXa21, xa13 and xa5 through marker-assisted breeding into an elite, high-yielding fine-grain type rice variety,Samba Mahsuri(SM) FBR1-15EM, a near-isogenic line (NIL) of Samba Mahsuri possessing Xa33 served as thedonor and Improved SambaMahsuri (ISM), a near-isogenic line of SM possessing Xa21, xa13 and xa5 servedas the recurrent parent. Marker-assisted backcross breeding was adopted to combine these four-genes intoSamba Mahsuri using gene specific markers. A set of 65 parental polymorphic SSR markers distributeduniformly throughout the rice genome were used for background selection. At BC1F2, a total of nine plantswhich were homozygous for all the four target resistance genes and closely resembling ISM were identifiedand selfed. Two promising BC1F4 lines (BB4G12-1-13-14 and BB4G12-8-44-2) possessing a high level ofresistance against BB along with yield, agro morphological traits and grain quality attributes equivalent to thatof SM have been shortlisted for multi-location testing and release to farmers.
