摘要
以广东省 2 0 0 2年早季杂交水稻 (中熟组 )区试资料为例 ,探讨了DTOPSIS法在水稻新品种综合评价中的应用。结果表明 ,该法分析结果与区试常规分析结果基本一致 ,但该法比单用产量分析更为合理。对DTOPSIS法在水稻新品种综合评价中的有关问题进行了讨论。
Taking the evaluation of the tested rice varieties in Guangdong Provincial Early Hybrid Rice Regional Trial of the year 2002 as an example, the method of Dynamic Technique for Oder Preference by Similarity to Ideal Solution (DTOPSIS) was used to appraise new rice varieties. It was found that DTOPSIS was fit to be applied in appraising new rice varieties. It showed a similar ordering trend to the traditional analytical method of regional trials. However, DTOPSIS is a better method in the integrated evaluation of new varieties, because it appraises a variety by multiple characters but not by only a single character (grain yield). Some issues in application of DTOPSIS in appraising new rice varieties were also discussed in this paper.
