摘　　要：应用关联分析法 ,对桔类 1 8个品种果实品质进行了综合评价 ,明确了最优品种。与等权关联度相比较 ,加权关联度的评估结果更能反映出果实品质多个性状的实际表现。By using relational grade analysis of the grey system theory, the fruit quality of eighteen orange varieties were multifactorially evaluated. The best orange variety was defined. Compared with equal relational grade analysis, the weighted grade analysis is more reliable in assessing the actual expression of fruit quality traits. To form the “perfect variety” and to give different traits with different weights are the key steps in relational grade analysis.
