Comparison of the micro-morphological characteristics of pollen grain and leaf epiderm among diaploid Thinopyrum elongatum, Elytrigia intermedia, common wheat and octoploid Tritielytrigia types were carried out by observation under scanning electronic microscope.
方法］通过扫描电镜对二倍体长穗偃麦草、中间偃麦草、普通小麦、和八倍体小偃麦的花粉粒和叶表面的微观形貌特征进行了比较。

Octoploid tritielytrigia type TAI-7045 showed immunity to yellow rust and middle resistance powdery mildew. CH-9916 is immune to yellow rust in seedling and adult stages, powdery mildew in seedling and adult stages, and their powdery mildew middle resistance. These suggested that the high powdery mildew-resistance in Octoploid tritielytrigia TAI-7045 had probably been transferred into common wheat.
通过对条锈病及白粉病抗性评价，结果表明：亲本八倍体小偃麦TAI-7045、小偃麦衍生系CH-9916对条锈病表现免疫，对白粉病表现中抗，而另一亲本"晋麦33"对条锈病、白粉病表现高感，推测小偃麦衍生系CH-9916抗条锈病及白粉病的基因均来源于代换的一对染色体——亲本八倍体小偃麦TAI-7045即来源于中间偃麦草。
