| 摘 要： | 1973~1979年间,在广西稻瘟病圃试验了11198个水稻品种。有一些抗病品种曾以人工接种测定.其中23个品种呈现稳定的高抗至中抗反应。 试验结果表明,红脚占、砦糖、金围矮是广谱抗稻瘟病的品种。 初步观测表明,叶瘟与穗瘟的抗病反应是相关的。 文中讨论了对稻瘟病抗病性的类型,未发现范德普兰克(1968年)描述的对病原的所有小种反应一致的水平抗性品种。 |

| Abstract: | During 1973 to 1979, 1 1198 rice cultivars were tested in Guangsi rice blast nuseries for their resistance. Some resistant cultivars were further tested by artificial inoculations. As a result,23 of them showde highly to moderately stable resistant reaction. Hong-Jiao-Zhan, Chai-tang, Jin-wei-ai were cultivars with broad spectrum of resistance to blast. Preliminary observations revealed that reactions to leaf and neck blast were correlated. In this paper, problem on the type of disease resistance to rice blast are discussed.The so-called horizontal resistance portrayed by van der Plank (1968) has not been demonstrated in the present study. |
