DETECTION CENTRIC TRANSLOCATION 1R <sub>S</sub>. 1B <sub>L</sub> BY USING MOLECULAR MARKERS IN BREEDING MATERIAL OF SOFT WHEAT
Using PCR-detection of molecular markers (Xrems1303, SR1R003, w-sec-P3/P4, GliB1.1, GliB1.2, Xgwm18, Xgwm550) in F <sub>4</sub> population showed the centric translocation 1R <sub>S</sub>.1B <sub>L</sub>, which locus Sec-1 is replaced by a fragment of chromosome 1B <sub>S</sub> of wheat Gli-B1/Glu-B3 locus and which also contains a proximal segment of chromosome 1R <sub>S</sub> carrying resistance genes to powdery mildew (Pm8), leaf, stem, yellow rust (Lr26, Sr31, Yr9, respectively). The proposed approach is effective for the identification in breeding material of wheat genotypes with centric translocation 1R <sub>S</sub>.1B <sub>L</sub>.
