运用灰色综合评判法综合评价国家黄淮海夏大豆区试品种

Evaluation on National Summer Soybean Regional Trial Varieties in Huanghuaihai Region by Using Grey Comprehensive Evaluation Method

运用灰色综合评判法,对2015年国家黄淮海夏大豆品种区域试验南片B组试验数据进行分析。综合15个主要性状指标,对10个参试品种的表现进行综合评价,排出了各参试品种(系)的综合评判等级次序,结果总趋势与实际产量表现基本一致,与联合方差分析的结果也基本一致,个别品种位次有变动。灰色综合评判法是传统评价方法的一种直观补充,简便易行,在育种材料的评价中可以广泛应用。该研究可为夏大豆新品种(系)的选育和合理评价提供科学依据和方法。

Using grey comprehensive evaluation method,the experimental data of summer soybeanvarieties group B in southern Huanghuaihai region in2015was analyzed.Integrating15important traits,the performances of10varieties tested were assessed comprehensively,and the ranking orders of allvarieties tested were listed.The general trend was consistent with that of the actual productionperformance and the union variance analysis result,though orders changed in certain variety.Greycomprehensive evaluation method is simple and easy,which is a direct-viewing supplement to thetraditional appraisal method,and could be extensively applied in evaluation of breeding materials.Thestudy provides scientific basis and methodology for breeding and rational evaluation of summer soybeannew varieties.
