[Objective] To scientifically and reasonably research the new wheat variety (line). [Method] Regional test data in 2016-2017 were used. 17 main characters of 17 new wheat varieties were analyzed by gray relational analysis grade method. [Result] Gray weighted relation degrees of Zhoumai 36, Hefeng 3, Xinmai 35 and Zhongyu 1220 were the top with relatively goog comprehensive characters, which was basically the same with their actual situation. However, gray weighted relation degrees of Anke 1502, Shengmai 101, Wansu 321, Chuangxin 118 and Tianmin 346 were relatively low, which was suggested to be eliminated. [Conclusion] This research provided references for the breeding and accreditation of wheat varieties.%[目的]科学合理地评价小麦新品种 (系) .[方法]利用2016—2017年度国家区域试验数据, 应用灰色关联度分析法对17个小麦新品种 (系) (含对照) 的17个主要性状进行分析.[结果]周麦36号、禾丰3号、新麦35、中育1220的加权关联度居前4位, 综合性状较好, 这与品种实际表现基本一致;而安科1502、圣麦101、皖宿321、创新118、天民346共5个品种的关联系数排名较低, 建议淘汰.[结论]该研究为小麦品种选育和审定提供参考.
