众所周知,选育和利用抗病品种来防治病害是最经济有效的措施。在过去的工作中,从研究到应用,在学术观点到研究方法,有各式各样的设想和做法,虽然培育和推广了大批的抗病品种并在理论水平上有很大的提高,但抗病品种推广后抗病性丧失的恶性循环问题至今仍未能很好地解决,本文拟对抗病品种选育和策略问题作些探讨。

It is known to all that it is the most economical and effective measure to select and use resistant varieties to control diseases. In the past work, from research to application, from academic point of view to research methods, there are various assumptions and practices. Although a large number of resistant varieties have been cultivated and popularized and greatly improved at the theoretical level, The vicious cycle of disease resistance loss after the popularization of disease-resistant cultivars has not been well solved so far. This article intends to discuss the breeding and strategy of disease-resistant cultivars.
