国际水稻所水稻新株系的抗性评价

为了进一步扩大我国稻种资源,丰富水稻育种材料,引进了165份国际水稻研究所在非洲进行穿梭育种的水稻新株系,于2011年和2012年在湖北生态条件下进行稻瘟病抗性、白叶枯病抗性和褐飞虱抗性的评价。评价结果表明,在165份新株系中有14份株系在宜昌和恩施2个稻瘟病病圃鉴定均表现抗或中抗稻瘟病,有40份株系同时高抗或抗白叶枯病菌株ZHE173和GD1358,有19份株系抗或中抗褐飞虱,有7份株系同时抗白叶枯病和稻瘟病,有8份株系同时抗白叶枯病和褐飞虱,有1份株系同时中抗稻瘟病、褐飞虱和白叶枯病。部分材料正在作为中间材料用于水稻育种。

The Evaluation of Blast, Bacterial Blight and Brown Planthopper for Rice Breeding lines from IRRI

In order to expand germplasm resources and rich genetic resources in rice breeding, 165 rice breeding lines introduced from International Rice Research Institute (IRRI) were evaluated for blast, bacterial blight and brown planthopper in 2011 and 2012 in Hubei Province, China. The resistance identification results showed that 19 lines were resistant to brown planthopper, 40 lines were resistant to bacterial blight, 14 lines were resistant to blast, 8 lines were resistant to both bacterial blight and brown planthopper, 7 lines were resistant to both bacterial blight and blast, and one lines were resistant to bacterial blight, brown planthopper and blast. Some of lines were used in breeding programme.
