新引特色小麦品种（系）灰色关联度分析.doc1 新引特色小麦品种(系)灰色关联度分析摘要: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 9039 7 综合性状表现差,不适宜在该地区种植。关键词:特色小麦;灰色关联度分析;引种;综合评价中图分类号: +9 ; O159 文献标识码:A 文章编号: 0439-8114 ( 2013 ) 17-4048-04 Grey Correlative Degree Analys is on the Newly Introduced Special Wheat Cultivars ( Lines ) LIU Chun-ying1 , SUN Xue-ying1 , ZHU Ti-chao1 , CHEN Guang-rong2 2 ( Three Gorges Academy of Agricultural Sciences , Chongqing 404155 , China ; Three Gorges Vocational College , Chongqing 404155 , China ) Abstract : 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 prehensively evaluate 15 main characters of 16 special wheat varieties ( lines ) in the cultivars introduction parative test of special wheat cultivars ( lines ) conducted by Chongqing Three Gorges Academy of Agricultural Sciences in 2012. The results showed that the order prehensive 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 prehensive evaluation of newly introduced wheat cultivars ( lines ). Based prehensive 3 evaluation , it was found that Waxy Wheat 90398 , Jinuo No. 1 and Yujiaohei No. 1 performed b
