摘　　要：采用传统方法和改进方法(取名为茎枝菌液浸泡法)对马铃薯的青枯病抗性进行了鉴定和评价,其结果是一致的,但茎枝菌液浸泡法更加简便快速、经济有效、可操作性和可重复性更好,并且在番茄的青枯病抗性鉴定上也得到了验证。该方法对于茄科作物的种质资源抗病性评价和筛选,特别是对于病菌诱导产生抗性的抗(感)病植株的快速鉴定及其幼苗的先期快速筛选具有重要意义,可望成为一种理想的茄科作物室内抗病鉴定方法。Traditional methods and a modified identification method, named as ＂ Stem Culture in Bacterial Solution Method＂ , were used to identify the resistance to Ralstonia solanacearum in potato germplasm. The resuits showed that the modified identification method was more economic and repeatable, simpler and easier to be operated compared to the traditional methods. The new method also can be used to identify the resistance in tomato and tobacco germplasm.
