英文摘要	类番茄茄(Solanum lycopersicoides)高抗黄瓜花叶病毒(Cucumber mosaic virus,CMV)。通过4次独立试验,对来自类番茄茄LA2951的渐渗系(Introgression Line,IL)采用摩擦接种法,人工接种CMV 亚组Ⅱ进行了筛选,定位了8个抗CMV 的QTL,它们分别位于番茄第2、7、8、9、10、11和12染色体上,均可显著降低植株的病情指数,与前人已鉴定的来自多毛番茄(S. habrochaites)LA1777和智利番茄(S. chilense)LA0458的抗CMV 位点不同位,为抗CMV 新位点。通过对抗CMV 的IL 初步分析发现,这些IL 包含的QTL 呈现不完全显性遗传效应,QTL 聚合为完全加性效应。; Solanum lycopersicoides showed high resistance to Cucumber mosaic virus(CMV). An introgression line(IL) population derived from a nightshade related species S. lycopersicoides LA2951 was used to identify the involved loci for resistance to CMV by rub-inoculation in four independent experiments. In total,8 QTLs for resistance to CMV located on chromosome 2,7,8,9,10,11 and 12 were found respectively. Percentage of disease index(PDI)was significantly decreased in these ILs. All QTLs were new loci when compared those identified previously from S. habrochaites LA1777 and S. chilense LA0458. The genetic analysis of these QTLs showed incompletely dominant. The interaction of these QTLs presented complete additive effect. The results provide a prospect for breeding of CMV resistance in tomato.
