对我省稻瘟病菌生理小种鉴定结果表明,不同地区的生理小种是不一致的。根据生理小种分布情况,相应地利用品种的抗病性,实行品种的合理布局,是防治稻瘟病的经济而有效的措施。为此,明确水稻品种对稻瘟病菌生理小种的反应,对品种的评价和利用是十分必要的。现将1978—1981年我省稻瘟病菌生理小种对 The identification of the physiological races of Pyricularia grisea in our province showed that the physiological races in different regions were inconsistent. According to the distribution of physiological race, the appropriate use of varieties of disease resistance, the implementation of a reasonable layout of varieties, is the prevention and control of rice blast economic and effective measures. Therefore, it is necessary to clarify the response of rice varieties to physiological races of Magnaporthe grisea, and to evaluate and utilize cultivars. Now 1978-1981 Pyricularia grisea physiological races
