Abstract
The hard red winter wheat Tangmai 4 did not develop symptoms of infection following inoculation with powdery mildew ( Erysiphe graminis DC. f. sp. tritici E. Marchal) isolates from regions of western Canada and northern China. Tangmai 4 exhibited resistance to stem rust ( Puccinia graminis Pers. f. sp. tritici Eriks. & Henn.) and leaf rust ( P. triticina Eriks.) races from western Canada. This wheat line was resistant to individual stripe rust ( P. striiformis Westend. f. sp. tritici Eriks.) races from the U.S. and Canada. Sequential C-banding and genomic in situ hybridization (GISH), and electrophoretic analyses of high molecular weight glutenins and gliadins demonstrated that Tangmai 4 carried a pair of T1BL.1RS wheat-rye ( Secale cereale L.) translocated chromosomes. Since the genes located on T1BL.1RS are no longer effective in controlling powdery mildew and the rust diseases, Tangmai 4 must carry additional genes for resistance to these diseases, which makes it a valuable resource for the improvement of resistance in wheat against these diseases
