Two RAPD molecular markers located on different arms of 2Ai-2 chromosome from Thinopyrum intermedium were selected and the generations of the hybrid generation derived from Zhong 4 Awnless and wheat were analyzed. Two chromosome translocation lines were screened for wheat breeding program to control BYDV.

本研究采用RAPD方法，对具2Ai-2端体和完整染色体异附加或异代换系进行分析，从随机引物中，选出两个分别位于2Ai-2染色体两臂上的分子标记，然后用这两个标记对中间偃麦草和普通小麦的杂交后代进行筛选，选出小麦抗黄矮病易位系新材料。

Thinopyrum intermedium,one of the relative species of common wheat,is a kind of dominant wheat germplasm resource for the resistance to stripe rust in wheat genetic improvement. With using Chinese spring phlb as recurrent parents and awnless Zhong 4(a partial chromosome of Thinopyrum intermedium)as donor parents,that is backcross selection,the offspring BC_2F_(7～9)were acquired.Cytology check and genome in situ hybridization, were used for the translocation lines and substitution lines detection.

本研究采用常规杂交并辅抗性鉴定等方法，以中国春phlb突变体为轮回亲本，利用无芒中4，转育中间偃麦草的抗条锈性，并通过细胞学和DNA原位杂交检测，鉴定和筛选普通小麦—中间偃麦草的抗条锈病异代换系或易位系。

Analysis of this pattern revealed 300 inversions and translocations that have occurred since divergence of these two species.
