玉米丝黑穗病是玉米重要病害之一,曾在一度时期得到控制,但近年来又有回升,并且日趋严重,成为当前生产上的问题之一。目前防治办法主要是采用抗病品种,辅以其他农业措施,因此鉴定玉米不同品种、自交系的抗病性就十分必要,我们从1977年开始进行了这项工作。一、鉴定材料与方法供鉴定用的材料,大多由我院所属单位的玉米组供给,少数材料来自各县种子部门。鉴定是在人工接菌条件下进行的。每年秋季
Corn smut is one of the most important diseases of maize. It was controlled once in a while. However, it has been picked up again in recent years and becomes more and more serious. It has become one of the problems in current production. At present, the main methods of prevention and treatment are the use of resistant varieties, supplemented by other agricultural measures. Therefore, it is necessary to identify the disease resistance of different varieties and inbred lines of maize. We started this work in 1977. First, the identification of materials and methods for the identification of materials, mostly by the hospital affiliated units of corn supply, a small number of materials from the county seed sector. Identification is carried out under conditions of artificial inoculation. Every autumn
