摘要: 【目的】 综合评估青贮玉米新品种的优劣,为青贮玉米推广提供依据。【方法】 应用灰色关联度分析法和DTOPSIS法对2014年国家黄淮海地区青贮玉米区域试验12个参试种的13个性状进行综合分析,并用最大差异率法和区分度法对两种分析方法进行比较。【结果】 灰色关联度分析法和DTOPSIS法对参试种都能做出较为客观全面的评估,其中,大京九26青贮玉米品种生物干重18 742.5 kg/hm2,较对照种增产12.5%,达极显著差异水平(P<0.01),两种综合评估法排序均居第1位,表现为生育期适中、抗倒伏、抗小斑病、中性洗涤纤维含量较低、淀粉含量较高;12个参试种生物干重方差分析结果排序依次为V9>V1>V10>V7>V3>V5>V12>V4>V2>V8>V11>V6,各参试种生物干重排名与灰色关联度分析法和DTOPSIS法排序的秩相关系数分别为0.930 1、0.902 1,表明两种综合分析方法都能真实地反映青贮玉米品种的优劣;DTOPSIS法Ci最大差异率达84.6%、区分度0.733 3,优于灰色关联度分析法。【结论】 DTOPSIS法较易区分参试种的优劣,是一种综合评估青贮玉米品种的较好方法。

Abstract: 【Objective】 To comprehensively evaluate the silage corn new varieties and provide basis for the promotion of silage corn.【Methods】 Grey correlation analysis and DTOPSIS method were utilized to comprehensively analysis 13 traits of the 12 varieties from the national regional test of silage corn in Huang-Huai-Hai area in 2014. And the two methods were compared by the maximum difference rate method and discrimination method.【Results】 The two methods could make objective and comprehensive evaluation for the varieties. Among them,the biological dry weight of silage corn variety Dajingjiu 26 was 18 742.5 kg/hm2,12.5% higher than that of the control,which reached a very significant level(P<0.01). The biological dry weight of it ranked the first obtained in the two methods. The variety,Dajingjiu 26,had the characteristics of moderate growth period,lodging resistance,small leaf spot resistance,low content of neutral detergent fiber and high starch content. The results of variance analysis of biological dry weight of the 12 varieties were in the order of V9>V1>V10>V7>V3>V5>V12>V4>V2>V8>V11>V6. For the biological dry weight of the varieties,the rank correlation coefficients of grey correlation analysis and DTOPSIS method were 0.930 1 and 0.902 1 respectively,and the two comprehensive analysis methods could truly reflect the advantages and disadvantages of the silage corn varieties. The maximum difference rate of Ci of DTOPSIS method was 84.6%,and the discrimination degree was 0.733 3,which was better than that of grey correlation analysis.【Conclusion】 DTOPSIS method could easy to distinguish the advantages and disadvantages of the tested varieties,and it was also a better method for comprehensive evaluation of silage corn varieties.

Key words: Silage corn, Grey correlation analysis, DTOPSIS method, Comprehensive evaluation
