摘　　要：[目的]为筛选出适应皖北地区种植的水稻品种,同时为水稻新品种的育种、精准定位推广提供依据。[方法]以17个水稻品种的21个性状为试验材料,采用基于灰色关联度分析法和DTOPSIS法对水稻品种的适应性进行全面的综合评价,分析比较品种间的差异。[结果]灰色关联度分析法和DTOPSIS法都能对水稻新品种进行较全面综合评价,准确反映品种的优劣。2种方法的综合评价结果存在差异。在赋予相同权重的情况下,灰色关联度分析结果显示,参试水稻品种与理想品种之间的关联度εt(k)值的最大差异率为26.7%;DTOPSIS法分析结果显示,参试品种与理想解的相对接近度Gi值,其最大差异率为70.0%。最大差异率从大到小依次为Gi值、εt(k)值、产量差异。DTOPSIS法更能体现品种间的差异和反映品种优劣,较灰色关联度分析法更适合用于水稻新品种的综合评价。[结论]韵两优丝苗、赞两优570、悦两优2646和韵两优332这4个优良品种在皖北适应性、稳定性、丰产性和抗病性均较好,可进一步试验、示范及推广。DTOPSIS法是综合评价皖北新水稻品种优劣的好方法。[Objective] To select rice varieties suitable for planting in northern Anhui,and to provide a basis for breeding,precise positioning and promotion of new rice varieties.[Method] Two methods of grey correlation analysis and DTOPSIS were applied to comprehensively evaluate the adaptability of 17 rice varieties including 21 characters.The differences among varieties were analyzed and compared.[Result] The gray correlation analysis method and DTOPSIS method could make comprehensively and integrative evaluations of new rice varieties and accurately reflect their advantages and disadvantages of varieties.And the results of the two methods differed.Under the case of giving the same weights,the results of the gray correlation analysis showed that the correlation coefficient εt(k) differed among the participating rice varieties and the ideal variety,and its maximum difference rate was 26.7%.The results of DTOPSIS method analysis showed that the relative proximity factor Gi differed among the participating rice varieties and the ideal variety,and its maximum difference rate was 70.0%.The maximum difference rate was in the order of Gi > εt(k) > yield difference.It indicated that the DTOPSIS method could reflect the differences among varieties and reflect the advantages and disadvantages,and was more suitable for the comprehensive evaluation of new rice varieties,comparing to the gray correlation analysis.[Conclusion]The four excellent rice varieties of Yunliangyousimiao,Zanliangyou 570,Yueliangyou 2646 and Yunliangyou 332 had better adaptability,stability,yield and disease resistance in northern Anhui.And these four varieties could be considered for further test,demonstration and promotion.The DTOPSIS method was a reasonable method to comprehensively evaluate the advantages and disadvantages of new rice varieties in northern Anhui.
