摘　　要：采用动态逼近理想解排序法(DTOPSIS法)对9个供试糯玉米品种的17个性状进行综合评价。建立评价矩阵A,根据育种目标进行无量纲化处理得矩阵Z,将各个性状指标分别赋予不同权重W_j后,建立决策矩阵R,通过决策矩阵R得出各性状的正理想解(X^+_j)和负理想解(X_j),最终得到各品种对理想解的相对接近度C_i,据此对各品种的优劣进行评判,C_i值越大综合性状越好。分析结果表明:8个糯玉米新品种的C_i值均大于桂糯519(CK),综合表现优于桂糯519(CK)。根据C_i值排序,亚航糯3号、天贵糯932、银碟糯773、天贵糯937分别居前4位,说明这4个品种在春季种植表现出较好的丰产性和较优良的综合品质,是具有较大应用价值的优质品种。This study tested 17characters of 9 waxy maize varieties by DTOPSIS method, set up valuation matrix A, according to the breeding goals, obtained the matrix Z by dimensionless processing; set up decision matrix R, when different characters indexes were given different weights Wj, obtained the the positive ideal solution （ X＋j ） and the negative ideal solution （X-j） of different characters, finally obtained the relative approach degree Ci, then judged the advantages and disadvantages of each variety, the higher the Ci value, the better the comprehensive characters. The results showed that the Ci values of 8 new waxy maizes were larger than GuinuoS19 （ CK ） and the comprehensive traits were better than GuinuoS19 （ CK ） . According to the order of C- value, the top four waxy maizes were Yahang No.3, Tianguinuo932, Yindietiannuo773 and Tianguinuo937, indicating that the four varieties planted in spring showed higher yield and better quality, had good quality and great application value.
