10个小麦新品种(系)抗小麦叶锈性评价
Evaluation of Wheat Leaf Rust Resistance of 10 New Wheat Cultivars (Lines)
摘要
Abstract
[ Objective ] The objective of this study was to investigate the leaf rust resistance of 10 new wheat cultivars (lines) including Henong 5290, Henong 58-3, Henong 825, Henong 826, Henong 827, Henong 6049, Henong 6251, Henong 6425, Henong 7106 and Henong 9206. [Method] Sixteen Puccinia triticina strains with different virulence patterns were used for seedling genes postulation and 6 strains of them for the test at adult stage. A series of STS and SCAR markers linked to 15 wheat leaf rust resistance genes were used for marker assisted selection of these tested cultivars (lines). [Result] Lrl was found in cultivars Henong 6425 and Henong 9206. Lr26 was detected in 7 cultivars including Henong 825, Henong 826, Henong 827, Henong 6049, Henong 6251, Henong 6425 and Henong 9206. Henong 5290, Henong 58-3, Henong 825 and Henong 6251 were postulated containning other or unknown leaf rust resistance genes, and they were resistant to most of the P. triticina strains tested. [Conclusion] Henong 58-3, Henong 5290, and Henong 6251 showed potential use in wheat breeding for leaf rust resistance.关键词
