摘要
采用灰色关联度分析法、同异分析法、同一度分析法、DTOPSIS分析法、模糊隶属函数分析法,对云南甘蔗野生割手密血缘F2代17份材料4年的调查结果进行综合分析。结果表明,5种分析方法对参试材料的总体排序是08-719、08-727、08-729、08-685、08-821、08-728、08-683、08-676、08-684、08-382、08-722、08-677、08-720、08-782、08-819、08-818、08-721,其中有4份材料超过对照ROC22,14份材料超过对照粤糖93-159;5种分析方法的区分度最大的是DTOPSIS分析法,为0.8128,其次是模糊隶属函数分析法、同异分析法、同一度分析法、灰色关联度分析法,分别为0.7664、0.5046、0.3494、0.3180;5种方法准确度最高(离均值最小)的是同异分析法,为0.0325,其次是灰色关联度法(0.0648)、模糊隶属函数分析法(0.1014)、DTOPSIS分析法(0.1148)、同一度分析法(0.1242)。
New seventeen Saccharum spontune F2 in Yunnan was analyzed by the gray correlation degree,the similarity-difference analysis,the identical degree,the DTOPSIS（ Dynamic Technique for Order Preference by Similarity to Ideal Solution） and the fuzzv subordinate function. The results showed that the holistic order was 08-719,08-727,08-729,08-685,08-821,08-728,08-683,08-676,08-684,08-382,08-722,08-677,08-720,08-782,08-819,08-818 and 08-721. Meanwhile,there were four materials exceeding control variety ROC22 and fourteen materials exceeding Yuetang93-159. The divisional degree of the DTOPSIS was the most in five methods,that was 0. 8128. Then the divisional degrees of the fuzzv subordinate function,the similarity-difference analysis,the identical degree and the gray correlation degree respectively were 0. 7664,0. 5046,0. 3494 and 0. 3180. The exact degree of the similarity-difference analysis was the best（ Deviation from average was the least） in five methods,then the exact degrees of the gray correlation degree,the fuzzv subordinate function,the DTOPSIS and the identical degree respectively were 0. 0325,0. 0648,0. 1014,0. 1148 and 0. 1242.
