| 摘 要： | 采用灰色关联度分析法和DTOPSIS法对烤烟引进新品种进行了多性状的综合评判,研究结果表明:两种分析方法都能较全面的评判品种,但两种综合评价方法的评判结果存在一定的差异。在赋予了相同权重的情况下,灰色关联度方法品种间差异不大,DTOPSIS法评价结果中Ci值差异明显,能更好反映品种的优劣,在参试品种较多或需对参试品种归类或淘汰时,DTOPSIS法比灰色关联度法更加适用。

| Abstract: | Introduced flue-cured tobacco varieties were evaluated by DTOPSIS and gray relational analysis.Results showed that significant difference in evaluation existed in two methods.Given the same weight,grey relational analysis shows no significant differences among variet ies,while DTOPSIS has different results.It implied that DTOPSIS is more appropriate,especially when a large number of testing varieties were needed to be classified. |
