摘要： Four red spring wheat (Triticum aestivum L.) lines, L658 (Reg. No. GP-971, PI 672537), L693 (Reg. No. GP-972, PI 672538), L696 (Reg. No. GP-973, PI 672539), and L699 (Reg. No. GP-974, PI 672540), were developed at the Provincial Key Laboratory of Plant Breeding and Genetics, Sichuan Agricultural University of China from the cross 'MY11'/YU25, the latter of which was derived from a cross between common wheat (Triticum aestivum, 2n = 6x = 42, AABBDD) and Thinopyrum intermedium (Host) Barkworth & D.R. Dewey (2n = 6x = 42; JJJ(s)J(s)SS). The four wheat lines have high levels of resistance to Fusarium head blight (FHB) (mainly caused by Fusarium graminearum Schwabe) similar to those of the FHB-resistant genotypes 'Sumai 3' and 'Wangshuibai' based on results of experiments conducted in three different years in three different areas. In addition to FHB resistance, these lines also have strong resistance to both stripe rust (caused by Puccinia striiformis Westend. f. sp. tritici), with infection type (IT) = 0 or 0;, and powdery mildew (caused by Erysiphe graminis f. sp. tritici), with IT = 0. The results obtained in the Henan Province of China also show that these lines have suitable agronomic and morphological traits. These results indicate that the novel resistant wheat lines L658, L693, L696, and L699 could play an important role in wheat genetic improvement, especially for FHB, stripe rust, and powdery mildew resistance.
