苏联非黑钙土中心地带,冬小麦产量进一步提高的主要限制因素之一是病害,其中按危害程度来说,要算白粉病。该病对易感品种,在连种各类作物和施入大量肥料,尤其是氮肥时,特别危险。采取防治措施对这个病害是困难和无效的。因此,为了保护作物免于致病,必须培育和应用抗病品种。

One of the main limiting factors in further increasing winter wheat yield in the center of the non-Chernozem soil in the Soviet Union is disease, which, in terms of degree of harm, is a powdery mildew. The disease is particularly dangerous for susceptible breeds, even with a wide variety of crops and with large amounts of fertilizers, especially nitrogenous fertilizers. Taking control measures is difficult and ineffective for this disease. Therefore, in order to protect crops from pathogenicity, resistant varieties must be cultivated and applied.
