摘　　要：采用灰色关联度分析法和DTOPSIS法分别对烤烟区域试验中各参试品种进行了多性状的综合评判。结果表明,在产量、品质、抗病性三者兼顾的情况下,两种综合评价方法的评判结果基本相同,并与品种实际表现相符。但灰色关联度方法品种间差异不大,DTOPSIS法评价结果中Ci值差异十分明显,能更好地评价品种的优劣。Two analysis methods namely Grey correlation and DIOPSIS were employed for multi-trait evaluation of flue-cured tobacco varieties entered the variety test. The results showed that given attention to the yield, the quality and the disease resistance, the two evaluation methods gave the similar results and the results were in consistent with the actual performance of the tested varieties. By using the grey correlation analysis,there were no significant differences among the varieties,while by DTOPSIS,the differences among the Ci values were significant,it indicated that DIOPSIS can do better in evaluating the performances of the varieties.
