To combat the dreaded diseases in rice like bacterial blight (BB) and blast, host plant resistance has been advocated as the most suitable and sustainable method. Through the present study, we have successfully incorporated three major BB resistance genes, namely Xa21, xa13 and xa5 into NLR3449, a high yielding, blast resistant, fine-grain type, popular rice variety through marker-assisted backcross breeding. Foreground selection was carried out using polymerase chain reaction based, gene-specific markers, namely pTA248 (Xa21), xa13prom (xa13) and xa5FM (xa5) at each generation of backcrossing, while 127 polymorphic SSR markers spanning on 12 chromosomes were used for background selection and backcrossing was limited to two rounds. At BC₂F₁ generation, a single plant (NLR-87-10) with 89.9% recovery, possessing all the three BB resistance genes was forwarded to BC₂F₂ generation. A solitary BC₂F₂ plant, namely NLR-87- 10-106 possessing all the three resistance genes and 96% genome recovery was identified and advanced through selfing until BC₂F₄ generation by adopting pedigree-method of selection. Three best BC₂F₄ lines, possessing high level of resistance against BB and blast, andequivalent or superior to NLR 34449 in terms of yield, grain quality and agro-morphological traits were identified and advanced for multilocation trials.
