摘　　要：广抗13A是福建省三明市农科所育成的对稻瘟病抗性强、抗性谱广的籼型三系不育系。分析了近5 a利用广抗13A、泸香618A等不育系测配的884个杂交组合在稻瘟病重病区抗性鉴定结果,广抗13A配制的组合表现出较强的抗瘟性,说明广抗13A对F1的稻瘟病的抗性水平提高有显著效应。并就该不育系的利用问题进行了讨论。Guangkang 13A was a CMS line developed by Sanming Institute of Agricultural Science. In this paper, 884 hybridized combinations were analysed about blast resistance in heavy disease areas. The results showed hybridized combinations of Guangkang 13A displayed strong resistance. In the meanwhile, the paper also analysed the existing problems in utilization of the GMS lines.
