摘　　要： 用星座图聚类的方法对２８个玉米自交系进行了分析。结果表明：①计算所得的综合值可以客观地度量玉米自交系的综合性状，且玉米自交系的综合值具有相对的稳定性；②依综合值的大小，可以把２８个参试玉米自交系划分为性状各异的６个类群或简单地划分为优良、一般、较差３个等级；③星座图聚类是表型性状的聚类，聚类结果与自交系间的血缘无必然的联系。 inbred lines of maize were analyzed through the constellation graphical cluster methods.The results were as follow:①The complex of inbred lines of maize could be measured objectively by the complex character value and the complex character value of inbred lines of maize were relative stability.②28 inbred lines of maize were chassified into 6 clusters or three grades:good,general and bad different in complex character by the complex character value.③The constellation graphical cluster analysis was a method which based on the phenotypic character.There were no relationship between the result of constellation graphical cluster analysis and the kin of inbred lines.
