稻瘟病是由稻瘟病菌（Magnaporthe grisea巴尔.）是全世界最具破坏性的水稻病害之一。严重影响了水稻的产量和品质。培育抗病品种是防治该病最有效、最经济的途径。本研究以114个水稻单片段代换系为材料，在苗期接种16个稻瘟病菌系。114个SSSL中的替换片段分布在12条染色体上，覆盖水稻基因组的57.32%。其中15个SSSL的抗瘟性与HJX 74受体不同。SSSL W23-7-6-5-2-2表现出100%的抗性频率。在水稻第1、2、3、6、10、11和12染色体上共检测到11个抗稻瘟病QTL。在2.2- 46.2cM的染色体间隔上定位了10个QTL，其中6个QTL定位在10.0cM以下。11个QTL中有6个为本文首次报道。
Rice blast, caused by fungal pathogen Magnaporthe grisea Barr., is one of the most devastating rice diseases worldwide. It has greatly affected the rice production and quality. Development of resistant cultivars is the most effective and economical way for controlling this disease in rice. In this study, 114 of the single-segment substitution lines (SSSLs) in rice were inoculated at seedling stage by 16 rice blast isolates. The substituted segments in the 114 SSSLs distributed on 12 chromosomes with coverage of 57.32% of rice genome. Fifteen of the SSSLs were different in blast resistance from the HJX74 recipient. The SSSL W23-7-6-5-2-2 showed 100% of resistance frequency. A total of 11 QTLs for blast resistance were detected on chromosomes 1, 2, 3, 6, 10, 11 and 12 in rice. They were mapped at chromosomal intervals of 2.2–46.2 cM, of which 6 QTLs were mapped at less than 10.0 cM. Six of the 11 QTLs were first reported in this paper.
