Resistance to Fungal Diseases in Hybrid Progeny from Crosses between Common Wheat Variety Saratovskaya 29 and the Amphidiploid Triticum timopheevii/Triticum tauschii (AAGGDD)

The progeny of BC₆F_2–4–BC₉F_2–4 has been analyzed for resistance to brown rust (Lr genes) and powdery mildew (Pm genes). This progeny was obtained due to introgression of the alien material from the synthetic hexaploid wheat Triticum timopheevii/Aegilops squarrosa (= Triticum tauschiiaAGGDD, 2n = 42) into the common wheat variety Saratovskaya 29. Against the background of natural infection, the lines resistant to both diseases and to either of them were developed. The brown-rust and powdery-mildew resistance is controlled by one/two effective independent genes Lr and Pm.
