摘　　要：[目的]为挖掘冀东生态类型区夏玉米(Zea mays L.)生产的高产潜力,筛选适合当地气候条件栽培的优良玉米品种。[方法]采用7个优质玉米杂交品种(春喜11、唐玉1、浚单20、冀丰58、郑单958、三农201、京玉11),进行适应性、丰产性及抗逆性等方面对比试验。[结果]在基本苗6.66万株/hm2,相同的栽培管理条件下,7个参试品种的平均产量都在9 000～10 500 kg/hm2,存在一定的差异。唐玉1和京玉11是当地前几年的主推品种,抗逆性略好于其他品种,但在相同的植保管理措施下,其产量低于郑单958、浚单20。[结论]从综合经济性状表现来看,郑单958、浚单20、京玉11更适合在冀东生态类型区推广栽培。[Objective] The aim was to develop the high yield potential of summer maize in the Ecological Areas of the East Heber Province,select the good maize varieties suitable for the local climate.[Method] The comparative test of seven good quality hybrid maize varieties（Chunxi11,Tangyu-1,Xundan 20,Jifeng 58,Zhengdan 958,Sannong 201 and Jingyu 11） on adaptability,yielding ability and resistance was carried out.[Result] Under the same cultivation and management conditions,and 6.66×104 plants per ha,seven tested varieties’ average yield was 9 000-10 500 kg/hm2,had a certain difference.Tangyu-1 and Jingyu 11 was the local main cultivation maize varieties several years ago,their resistance was better than that of the other varieties,while under the same plant protection management measures,their yield was lower than that of Zhengdan 958 and Xundan 20.[Conclusion] Comprehensively considering the performance of economic traits,Zhengdan 958,Xundan 20,Jingyu 11 are preferably adapt to grow and promote in the Ecological Areas of the East Hebei Province.
