多抗小麦新品种扬辐麦5号的选育

为控制小麦黄花叶病及白粉病的危害,培育高产、多抗小麦新品种,以携带Pm4a抗白粉病基因高产小麦品种扬麦11为轮回亲本,以辐射诱变抗黄花叶病种质扬辐麦9311为供体亲本,通过回交转育方法,经辐射诱变和多年多点鉴定选择,育成高抗小麦黄花叶病、兼抗白粉病小麦新品种扬辐麦5号,2011年通过安徽省审定。该品种产量高,安徽省淮南麦区区域试验和生产试验较对照增产显著,小麦黄花叶病抗性达到高抗水平,抗白粉病,中抗纹枯病,品质指标达弱筋小麦标准,适合在长江中下游麦区种植。

Breeding of Yangfumai No.5 with Multiple Disease Resistance

To control the damage of wheat yellow mosaic disease and powdery mildew, new wheat cultivar with high-yield, disease-resistant was bred. Yangfumai 9311 with yellow mosaic disease resistant was used as donor parent to backcross with recurrent parent Yangmai 11, and combined with conventional breeding techniques and irradiation methods, a new wheat variety Yangfumai No.5 was developed and registered in 2011. Yangfumai No.5 with resistance of yellow mosaic disease and powdery mildew is suitable to grow in the Yangtze River region.
