摘　　要：本研究对34份热带、亚热带自交系进行了南方锈病抗性鉴定,发现了11份南方锈病抗性新种质;并对其中4份高抗种质进行了抗性遗传分析,发现4份外来种质对南方锈病的抗性呈主基因和主基因加微效基因复合控制的、比较复杂的遗传。The resistances of 34 tropical or subtropical maize inbred lines to southern rust were identified.There were 11 new maize germplasms resistant to southern rust.Among which,4 highly resistant germplasms were conducted genetic analysis.The results indicated that the 4 maize germplasms showed complex hereditary modes controlled by host gene or host gene combined with minor gene.
