摘要
为探求更加方便、快捷、有效的小麦品种区域试验分析方法,以2008-2009年度河南省小麦品种区域试验结果为资料,对作物品种区域试验中方差分析、模糊综合评判方法、灰色多维综合评估方法和同异联系势分析方法进行了比较研究。结果表明,四种分析方法各有千秋,方差分析理论与方法较为成熟,但只能分析单一性状,综合功能差;其余三种分析方法则综合功能强,对品种评价更加客观、全面。其中,灰色多维综合评估方法和同异分析方法区分度较好,更利于辨别品种优劣,尤其是同异分析方法计算简单,方便快捷,提供的试验信息更多,能够对多个性状进行综合差异显著性检验,是开展育种工作的良好工具和手段。
In order to exploit more convenient,fast and effective methods of experimental analysis of wheat variety regional test,using the Henan province regional wheat variety trial results in 2008-2009 as data,the four different analysis methods of variance analysis,grey multidimensional integrated evaluation,fuzzy comprehensive evaluation and similarity-difference analysis method were used and compared.Results showed that each of the four analysis methods had its own merits.The theory and procedure of variance analysis was applicable,with good results only for single character and without integrated functions,the remaining three analysis methods were with integrated functions and more objective and comprehensive to varieties evaluation.Among them,the grey multidimensional integrated evaluation and similarity-difference analysis method are better in differentiability,and more conductive to identify good and bad of varieties.In particular,the similarity-difference analysis methods was more available for calculating simple,convenient,test information,it,can carry on the comprehensive test of significance of difference for multiple characters,therefore it was good tools and means for breeding workers.
