Abstract—Powdery mildewis one of the destructive diseases of wheat in many regions of the world. Wheat-Thinopyrumintermedium derived line CH5382 conferring novel powdery mildew resistance was characterized using molecular and cytogenetic methods. The conventional GISH analysis probed by Th. Intermedium cannot detect the alien fragmentof CH5382. Two PCR-based Landmark Unique Gene markers (TNAC1102 and TNAC1567), which were assigned on wheat chromosome 2L and 5S, respectively, canamplfy unique bands of CH5382, and the bands were traced to wheat-Th. intermedium partial amphiploiddonor TAI7044 and Th. intermedium. The result suggested that CH5382 is a new wheat- Thinopyrumintermedium cryptic alien translocation line with powdery mildew resistance.

Index Terms—Cryptic alientranslocation, landmark unique gene markers, powdery mildew, Thinopyrumintermedium.
