灰色局势决策方法综合评价马铃薯新品种(系)

Comprehensive Evaluation of New Potato Varieties by Using Grey Situation Policy

根据灰色系统理论中的灰色局势决策原理,利用目标赋权获得加权局势决策方法,对2008年度国家马铃薯中晚熟西南组区域试验中的19个农艺性状观察值进行分析,排出了各参试品种的优劣,结果与方差分析基本一致。探讨了灰色局势决策在马铃薯品种评价中的应用。

According to the grey situation decision principle in the grey system theory, objective weight was used to obtain the weighted situation decision method. The observations of 19 agronomic traits in the national late-maturing potato regional trial of southwest region in 2008 were analyzed. The advantages and disadvantages of different test varieties were analyzed. And the results were basically consistent with the variance analysis. The application of grey situation decision in the evaluation of potato varieties was discussed.
