Rice bacterial leaf blight is the main disease in the coastal counties of our district. This year the disease area of 10 million mu, the loss is serious, in order to screen out the disease-resistant varieties as soon as possible this year, the hybrid cross-offspring material in our district bacterial blight occurred heavy Yunxiao County Chengguan commune low-lying land Field induced by natural and artificial inoculation network room, the results are as follows. Among the 154 materials tested, there were late nights × Jinnan night 3-1-1-①, Longhua night -1-4, Longhua night 2 -2-①, late nights × IR26-1-② , Long night × IR36-5-②, IR209 × Long late red 11-②, wide bag × Longhua night, Long night × IR26-1-2-①, Longnan night (early), Longte night -1, -1 -③, Long night × IR26-1-1-2-1, South Fan
