摘　　要：应用灰色关联度分析法对重庆三峡农业科学院2012年特色小麦引种品比试验的考察结果进行综合评价,以期为重庆市万州区及相似生态环境下的小麦品种(系)引种及推广提供参考依据。结果表明,16个小麦品种(系)的综合评价位次由高到低依次为糯小麦90398、济糯1号、予教黑1号、宛黑1号、渝麦7号(CK)、紫580-1、漯特麦2号、紫粒小麦-1、南充0001、周黑麦1号、SWD05、绿小麦、紫粒小麦、5B-6、糯小麦90397、冀糯200;加权关联度较等权关联度更能反映品种的实际表现,是综合评价小麦新引品种(系)的一种有效方法。经综合评价,筛选出糯小麦90398、济糯1号、予教黑1号3个品种表现较好,可进一步示范推广;紫粒小麦-1和宛黑1号可用作特殊育种材料;冀糯200和糯小麦90397综合性状表现差,不适宜在该地区种植。In order to provide reference for introduction and promotion of wheat cultivars(lines) in Wanzhou district of Chongqing city and similar ecological environments,grey correlative degree analysis was adopted to comprehensively evaluate 15 main characters of 16 special wheat varieties(lines) in the cultivars introduction and comparative test of special wheat cultivars(lines) conducted by Chongqing Three Gorges Academy of Agricultural Sciences in 2012.The results showed that the order of comprehensive evaluation score of the cultivars from high to low was Waxy Wheat 90398,Jinuo No.1,Yujiaohei No.1,Wanhei No.1,Yumai No.7(CK),Zi 580-1,Luotemai No.2,Zilixiaomai-1,Nanchong 0001,Zhouheimai No.1,SWD05,Greenwheat,Zilixiaomai,5B-6,Waxy Wheat 90397,and Jinuo 200.Compared with equal-weighted correlation degree,weighted correlation degree could reflect the actual performance of wheat cultivars more accurately,thus was an effective method for comprehensive evaluation of newly introduced wheat cultivars(lines).Based on comprehensive evaluation,it was found that Waxy Wheat 90398,Jinuo No.1 and Yujiaohei No.1 performed better among the 15 special wheat cultivars,worth further demonstration and popularization.Zilixiaomai-1 and Wanhei No.1 could be used as special breeding materials.Comprehensive characters of Jinuo 200 and Waxy Wheat 90397 were bad;thus the two cultivars was unsuitable for growth in Wanzhou.
