近年来随着小麦产量水平的提高和肥水条件的改善,白粉病日趋严重;此外,因条锈病抗源单一和新的生理小种不断出现,致使品种抗条锈性也日渐有所下降。两种病害的发生、蔓延对小麦高产、稳产构成严重威胁。为此,评价、筛选兼抗白粉病和条锈病的亲本,开发利用新的抗病基因已成为当务之急。 In recent years, with the improvement of wheat yield and the improvement of fertilizer and water conditions, powdery mildew is more and more serious. In addition, the resistance to stripe rust is also gradually decreased due to the continuous emergence of single and new physiological races of stripe rust. The occurrence and spread of the two diseases pose a serious threat to the high yield and stable yield of wheat. To this end, evaluation, screening and resistance to powdery mildew and stripe rust parents, the development and utilization of new resistance genes has become a top priority.
