DTOPSIS方法在紫花苜蓿新品种综合评价中的应用

Application of DTOPSIS Method in Appraising New Alfalfa Varieties

[目的]为筛选优良紫花苜蓿新品种提供参考。[方法]利用DTOPSIS法,对12个从国外引进的紫花苜蓿新品种的10个农艺性状进行综合评价分析,并讨论了DTOPSIS法在紫花苜蓿新品种综合评价中的有关问题。[结果]Pirate(海盗)、Siriver(四季绿)和Qqua-drella(昆德拉)3个品种综合性状好,产量高,适于推广应用。[结论]DTOPSIS法与常规产量分析结果基本一致,但比单用产量分析更合理,在紫花苜蓿新品种评价中具有广阔的应用前景。

[ Objective ] The study aimed to provide reference for screening excellent alfalfa varieties. [ Method ] Twelve introduced alfalfa varieties were evaluated using DTOPSIS method. Ten characters such as herbage yield, growth rates, plant height, ere were analyzed, and the rel- ative problems about DTOPSIS analysis in the comprehensive evaluation of new alfalfa varieties were discussed. [ Result ] The study showed that Pirate, Siriver and Quadrella owned the high yield and good quality and could be applied broadly. [ Conclusion] DTOPSIS method was more suitable for assessing alfalfa cultivars than the conventional yield analysis solely, and had broad application prospect in the alfalfa varieties＇ evaluation.
