| 摘 要： | 应用软Ｘ射线辐射选育的矮秆、优质、高产水稻新品种申香粳４号抗稻瘟病菌谱广，在所测的８８个菌株中（分属于７群２４小种），能抵抗８７个菌株中，抗菌株率达９８．８６％。而秀水１２２、秀水０４、丙６２０和花培１５等品种，抗菌株率较低，分别为１８．０％、２２．９９％、２３．１９％和１３．６４％。同时，在全国稻瘟病防治研究、品种抗瘟性联合鉴定试验中，申香粳４号品种抗叶瘟的抗性平均为２．５级，穗瘟抗性平均为０．６４级。与抗病对照品种Ｔｅｔｅｐ的抗性相近似。

| Abstract: | Sheng xiang jing 4 bred with soft -X - ray radiation was characterized by short stem, good quality, high yield, which had brod spectrum of resistance to more than 98. 86% of tested rice blast strains. But Xiu Shui 04,Xiu Shui122, Bing 620 and Hua Pei 15 had lower spectrum of resistance, they were 22. 99%, 18. 0%, 23. 19% and 13. 64%, respectively. During the test of the Chinese National Coordinating Research on Rice Blast and Uniform Resistance to blast indentification, avg. score of leaf blast and panical blast of Sheng Xiang Jing 4 was 2. 5 and 0. 64, respectively. And that was similar to rice resistance sources (Tetep). |
