稻瘟病是我省水稻的重要病害之一。但是有关湖北稻瘟病菌生埋小种的研究,除鄂西自治州对本地区稻瘟病菌生理小种进行了初步鉴定外,全省生理小种种群及其分布,尚无系统研究。本文是在对鄂西、鄂东南山区等地稻瘟病发生情况考察的某础上,从1986—1987年度对我省稻瘟病菌生理小种鉴定及其分布研究的初步总结。 Rice blast is one of the important diseases of rice in our province. However, there is no systematic research on the races and their distribution of the races of Magnaporthe grisea in Hubei except for the preliminary identification of the races of Magnaporthe grisea in Hubei Province. Based on the investigation of the occurrence of rice blast in western Hubei, southeastern Hubei and other places, this paper summarizes the identification and distribution of the physiological races of Pyricularia grisea in our province from 1986 to 1987.
