稻瘟病由Magnaporthegrisea,引起,是世界各水稻产区广泛分布的重要病害之一.实践证明,选用优良的抗病良种是稻瘟病综合防治的一项有效措施.然而一些抗病品种经推厂三五年后即渐趋感病,通常被认为是由于病菌生理小种迅速变化的结果.作者等用美国普度大学构建的一个散布的重复序列控针(MGR—586)对中国稻瘟病菌的限制
Rice blast is caused by Magnaporthe grisea, and it is one of the most important diseases widely distributed in all rice producing areas in the world. Practice has proved that the selection of fine resistant varieties is an effective measure to control rice blast. However, Five years after becoming susceptible to the disease, is usually considered as a result of the rapid changes in the germ races of bacteria. The author with the United States Purdue University to build a spread of repeated sequence control (MGR-586) of the Chinese Magnaporthe grisea restrictions
