Application of DTOPSIS method in evaluating new rice varieties
-
摘要: 运用DTOPSIS法,对2005年南方稻区长江中下游中水稻区域试验资料进行综合评价。结果表明,DTOPSIS法比单用产量进行分析更为合理,能将各品种的性状指标归纳为统一的量化综合指标,并能反映各品种的稳定程度;在所有参试品种中,Ⅱ优623、Ⅱ优1259和F301三者的Ci值最高,综合性状优良,与品种的实际表现一致;同时对DTOPSIS法在水稻新品种综合评价中的有关问题进行了探讨。Abstract: The mathematical DTOPSIS theory was used for the comprehensive evaluation of rice varieties.The data were obtained from the tests carried out in the middle and lower regions of the Yangtze River in 2005.The results indicated that the DTOPSIS method was superior to the yield analysis in variety selection for the following reasons:(a) it quantified indices of the relevant characteristics;and(b) it showed the genetic stability of the varieties.Of all varieties tested,the Ⅱ You 623,Ⅱ You 1259,and F301 had the greatest Ci values corresponding well with the actual performance.The paper also discusses existing problems relating to the comprehensive evaluation of new rice varieties by means of DTOPSIS.
