Abstract

The bacterial blight resistance gene Xa23 from a NIL CBB23 was introduced into a restorer line HK01，which is susceptible to bacterial blight, by crossing and markerassisted selection. Twelve homologous restorer lines with Xa23 were obtained through testing the flanking marker C189. An elite restorer line (K10) with high resistance to bacterial blight and good restoring ability and high yield potential was selected.

Key words： hybrid rice; bacterial blight; markerassisted selection; restorer line; resistance gene; breeding
