| 摘 要： | 采用灰色关联度分析法对26个参试青贮玉米（Zea mays）品种的7个性状进行综合评价。结果表明，在赤峰地区表现较好的青贮玉米品种有中农大青贮67、金岭18、雅玉青贮79491、金岭17、金岭21、青贮772、雅玉青贮29、东陵白、金岭37、中北青贮410，而YA473182、英国红（小）、东陵白（小）的生产性能较差。各项指标的权重大小顺序为株高＞穗位叶叶面积＞生物产量＞单株鲜质量＞单株干质量＞果穗鲜质量∶单株鲜质量＞果穗鲜质量，本研究结果可为赤峰地区乃至内蒙古农牧交错带青贮玉米引种及推广提供科学依据。

| Abstract: | The grey correlative degree analysis was applied to comprehensively evaluate the growth performance of 26 silage maize genotypes by seven characteristics.The 10 genotypes,including Zhongnongdaqingzhu 67,Jinling 18,Yayuqingzhu 79491,Jinling 17,Jinling 21,Qingzhu 772,Yayuqingzhu 29,Donglingbai,Jinling 37,Zhongbeiqingzhu 410,performed well,whereas the 3 genotypes had relatively low suitability in the Chifeng region.The order of weight index in the grey correlation analysis was height length>ear leaf area>biomass>plant fresh weight>plant dry weight>ear fresh weight per plant fresh weight>ear fresh weight.This study will provide the scientific evidence for introducing and extending silage maize in the Chifeng region,and even ecotone of agriculture and animal husbandry of Inner Mongolia. |
