小麦条锈病是我省小麦生产上的重要病害,流行年损失达3亿斤以上。随着抗病品种的推广和应用,有效地控制了锈病的流行。但是品种抗病的稳定性是相对的,锈菌本身又是寄生、专化性都很强的一个变异频繁的病菌,随着耕作制度,品种布局的不断改变,其组成也将不断变化。为此,我们逐年对小麦条锈菌生理小 Wheat stripe rust is an important disease in wheat production in our province, with a loss of more than 300 million pounds in the epidemic year. With the popularization and application of resistant varieties, the epidemic of rust is effectively controlled. However, the stability of varieties resistant to disease is relative, the rust itself is parasitic, specialization is very strong a frequent mutation of bacteria, with the farming system, the continuous changes in the layout of the variety, its composition will also continue to change. For this reason, we have a small annual physiological effect on wheat stripe rust
