摘　　要：为了明确广西稻瘿蚊生物型的变异动态和发掘广谱抗源和品种,采用国际稻瘿蚊苗期群体鉴定法研究了368份稻种资源对稻瘿蚊中国Ⅳ型的抗性,并监测了广西大新、乐业、岑溪和马山稻瘿蚊的生物型。研究发现大新和马山稻瘿蚊的生物型属于中国Ⅳ型,乐业稻瘿蚊的生物型属于中国Ⅱ型,岑溪稻瘿蚊的生物型属于中国Ⅲ型。发掘出对稻瘿蚊具有广谱抗性的高抗稻种资源13份、抗稻种资源4份和中抗稻种资源1份。In order to clarify the variation dynamics of rice gall midge(GM)biotype in Guangxi and screen broad-spectrum resistant resources and varieties,International Rice Research Institute evaluating method was applied to study the resistance of 368 rice resources on GM China typeⅣand the biotype monitoring of rice gall midge(GM)in Daxin,Leye,Cenxi and Mashan.The results showed that the biotype of GM in Daxin and Mashan was China typeⅣ.It was China typeⅡin Leye,and China typeⅢin Cenxi.Results of the resistance of rice resources to GM China typeⅣindicated that 13 high-resistant rice resources,4 resistant rice resources and 1 medium-resistant rice resource with broad-spectrum resistance to GM were discovered.
