| 摘 要： | Ug99(TTKS)为1999年在乌干达首次发现的秆锈菌新小种,对小麦抗秆锈病基因Sr31具有强毒力.此小种致病性极强,传播迅速,给全球小麦生产带来威胁.在肯尼亚用Ug99对我国118个小麦生产品种和材料进行抗病性鉴定结果表明,高感品种占98.3%.该小种一旦传入我国,将对小麦生产造成严重损失.笔者对国内外关于小麦抗Ug99遗传研究、抗病基因分子标记研究现状及我国应对措施进行了概述. |
| 关 键 词： | 小麦秆锈菌 Ug99 抗性基因 分子标记 |

| Abstract: | Ug99(TTKS),first found in Uganda in 1999,was a new virulent race of Puccinia graminis f.sp.tritici on Sr31.The race disseminated very fast and brought a horrible threat to production of wheat worldwide.Ug99 was a highly virulent race to 98.3% cultivars of 118 Chinese wheat cultivars or resistant sources based on the experiment conducted in Kenya.The research progress on wheat resistance heredity against P.graminis f.sp.tritici and development of molecular marker of genes Sr were summarized.And the preventio... |
