生理性青枯病在我国东南沿海一带的连作晚稻区时有发生。因其与气候变化直接相关，不仅面积大，且减产辐度也大。据作者研究，不同品种对该病的抗性差别很大。所以搞清抗源，尤其是培育既抗青枯病又高产的品种，不仅可供生产上应用，而且可作为选育抗青枯病品种的抗源。1生理性 Physiological bacterial wilt occurs in continuous cropping rice in the southeast coast of China. Because of its direct correlation with climate change, not only the area is large, and the scale of production is also large. According to the study by the authors, the resistance of different varieties to the disease varies greatly. Therefore, to find out the source of resistance, especially cultivating varieties that are both resistant to bacterial wilt and high yield, can be used not only for production but also as a source for breeding varieties resistant to bacterial wilt. 1 Physiological
