粟瘟病是谷子的主要病害,在我国北方各粟产区,每年都有不同程度发生为害、流行年份受害相当严重。实践证明,谷子品种对粟瘟病的抗性有明显差异,选育抗病品种是防治此病经济有效的措施。因此,弄清病菌小种类群、区系分布、消长变化规律,是选育和应用抗病品种的重要前提,自1979年,我们对我国粟瘟病菌生理小种的鉴别和分 Millet blast is the main disease of millet, and it has been harmed to different degrees every year in the millet producing areas in the north of our country. The epidemic year suffered a rather serious injury. Practice has proved that millet varieties of the blast resistance were significantly different breeding varieties resistant to the disease is a cost-effective measures. Therefore, it is an important prerequisite to breed and apply disease-resistant varieties by clarifying the small population groups, the distribution of fauna and the changes of the growth and decline of pathogen. Since 1979, we have identified and divided the Chinese races
