| 阳江市地处粤西沿海，台风发生频繁，晚造水稻生产处于台风高发季节，禾苗常因台风暴雨造成的物理损伤及洪涝引发白叶枯病暴发流行，是白叶枯病的重灾区。为提高阳江市水稻白叶枯病历史病区的水稻单产和品质，保证当地粮食安全生产，有必要在本地区加快推广抗白叶枯病的高产和优质水稻品
种。阳江市农科所根据近几年的广东省水稻区域试验数据，筛选出产量高、抗病性强的多个水稻新品种在病区进行示范表证，分析这些品种的抗病性和产量性状。结果表明，示范品种白香占和珍优9822 在阳江市白叶枯病历史病区对白叶枯病的防效显著，且表现出品质优、产量高、抗性强和广适性好等优良综合性状，阳江市地处粤西沿海，台风发生频繁，晚造水稻生产处于台风高发季节，禾苗常因台风暴雨造成的物理损伤及洪涝引发白叶枯病暴发流行，是白叶枯病的重灾区。为提高阳江市水稻白叶枯病历史病区的水稻单产和品质，保证当地粮食安全生产，有必要在本地区加快推广抗白叶枯病的高产和优质水稻品种。阳江市农科所根据近几年的广东省水稻区域试验数据，筛选出产量高、抗病性强的多个水稻新品种在病区进行示范表证，分析这些品种的抗病性和产量性状。结果表明，示范品种白香占和珍优9822 在阳江市白叶枯病历史病区对白叶枯病的防效显著，且表现出品质优、产量高、抗性强和广适性好等优良综合性状，推广前景看好。 |

| Abstract：Yangjiang city lies in the west of Guangdong，in which typhoon always occurs every year. The rice late season overlaps with the time that typhoon occur frequently. Rice plants could induce physical injure because of flood caused by typhoon and hard rain，which make rice bacterial blight arise and prevalent. To increase the rice yield and quality in heavy rice bacterial blight zone in Yangjiang and insure the rice safe production，it is requisite to adopt the rice varieties with high bacterial blight resistance in the local region. Agricultural and science research institute of Yangjiang screened out a few varieties with high yield and resistance，and did the demonstration feature identification in disease zone according to the data of rice region trial in recent years. The demonstration feature results showed that demonstrated varieties Baixiangzhan and Zhenyou 9822 with high yield，excellent quality，strong resistance and wide adaptability trait based on resistance identification and yield assessment showed highly effective prevention against rice bacterial blight in historical disease zone of Yangjiang city. The rice varieties Baixiangzhan and Zhenyou 9822 had promising application. These two resistant varieties were suggested to apply widey in the region of Yangjiang city. |
