小麦秆锈病是由一种寄生真菌形成的，它会对作物造成伤害。

Stem rust is caused by a parasitic fungus and devastates crops .

我国的小麦秆锈病菌对这80个抗源品种表现无毒力或毒性频率很低，这些抗源品种是我国小麦抗秆锈病育种的有效抗源。

Sp. tritici in China were unvirulence or had quite low virulence frequency to the 80 cultivars . They are effectively resistant resources for wheat breeding .

北方麦区120个小麦品种抗秆锈病基因的推导

Postulation of Resistance Genes to Stem Rust in 120 Wheat Cultivars in North China

该项目会涉及对这两个中心提供的几千种小麦样本进行筛选，选出有用的特性&该特性能够抵抗一种新的小麦秆锈病Ug99。

The project will involve screening several thousand wheat samples , provided by both centres , for useful traits & particularly against a new strain of stem wheat rust , Ug99 .
