DTOPSIS法在农作物品种稳定性综合评价上的应用初探

The Preliminary Exploration on Multifactorial Evaluation Crop Varieties′ Stability with Application of DTOPSIS Method

以1998年江苏省甘薯品种区试材料为例,初步探讨了DTOPSIS法综合评价农作物品种稳定性的方法和步骤。结果表明:DTOPSIS法能将各品种各性状指标归纳为统一的量化综合评价指标,这个指标可以全面地反映参试品种的稳定性程度,比单用产量进行统计分析更为合理;并进一步讨论了DTOPSIS法在遗传育种中的应用。

The paper primary explored the method of summarizing and valuing crop varieties′ stability using DTOPSIS with sweet potato regional test in Jiangsu province in 1998 as example. The results indicate that all characters of individual variety could be concluded into an index with united numerical value. The index could represent comprehensively the stability level of all variety tested. Comparing with traditional stability analysis, which only yeld index could be analyzed, a reasonable result could be obtained. In addition, the possibility of using DTOPSIS to crop breeding has been discussed.
