Construction of Immune Lines with Complex Resistance to Leaf Rust and Powdery Mildew in Common Spring Wheat Cultivar Saratovskaya 29

Construction of Immune Lines with Complex Resistance to Leaf Rust and Powdery Mildew in Common... 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.

Abstract

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.
