摘　　要：欧洲本土玉米种质多属硬粒型,具有较强的早熟性和抗逆性,导入欧洲优良玉米种质是拓宽我国适宜机械化种质基础的有效途径。通过整合分析欧洲西南、东南和北部玉米种质的配合力及杂种优势研究结果,发现有应用潜力的23个优良玉米群体,包括10个西班牙群体、6个法国群体、2个葡萄牙群体和5个瑞士群体。建议在适应性改良的基础上,将群体Enano Norteno/Vasco、EZS22与我国A群种质,群体Ain、Alegia、Bade、Berrobi、Lazcano、Tuy与我国B群种质构建复合群体,开展改良,拓宽我国玉米种质类群的遗传基础。Most of the European maize（ Zea mays L.） germplasm are earliness,density-tolerance and lodg resistance. Introgression of elite traits from European maize germplasm might be an effective strategy to broaden the genetic base of Chinese germplasm. By analyzing and summarizing general combining ability effects and heterosis responses among maize populations from the southwest,southeast and northern Europe,23 elite maize populations were identified,including ten Spain populations,six French populations,two Swiss populations,and five Portugal populations. Based on adaptation improvement and heterosis responses,we suggest that Enano Norteno/Vasco,and EZS22 could be introgressed into Chinese heterotic group A,and Ain,Alegia,Bade,Berrobi,Lazcano,and Tuy introgressed into Chinese heterotic group B to form and improve semi-exotic populations or pools,respectively,in order to broaden the Chinese maize germplasm base.
