国家第4轮甘蔗示范品种百色点DTOPSIS法综合评价

摘要

Eighteen characteristics of tenth sugarcane varieties of the Fourth National Sugarcane Demonstration were integrative evaluated by DTOPSIS. The results showed that theCi value of Guitang31, Guitang32 and Funong1110 were greater and their comprehensive traits better than that of ROC22 (CK), while the other six varieties were less and worse (or a little worse) than that of the CK. The evaluation results were consistent with the local field results.%采用逼近理想解排序法(DTOPSIS法)对国家第4轮10个甘蔗示范品种(品系)在广西百色点2新1宿的18个工农艺性状进行综合评价。分析结果表明，桂糖31号、桂糖32号和福农1110等3个品种(品系)的Ci值大于ROC22(CK)的Ci值，其他6个参试品种(品系)的Ci值小于ROC22(CK)的Ci值。根据DTOPSIS法分析原理，桂糖31号、桂糖32号和福农1110等3个品种(品系)综合表现优于ROC22(CK)，其他6个品种(品系)综合表现差于或略差于ROC22(CK)，评价结果与当地生产表现一致。
