[Construction of immune lines with complex resistance to leaf rust and powdery mildew in common spring wheat cultivar Saratovskaya 29].
Immune lines resistant both to leaf rust and to powdery mildew were constructed on the basis of common wheat cultivar Saratovskaya 29. Synthetic wheat Triticum timopheevii/Aegilops squarrosa (AAGGDD, 2n = 42) of Savov (Bulgaria) was used as a source of resistance genes. Using cytological analysis of BC2, we selected resistant plants (21") free from meiosis 1 (M1) defects. With these plants and continuous selection, BC8-BC9 immune lines were obtained. The lines were shown to carry new resistance genes differing from the known ones, and were proposed as donors of immunity to the diseases.
