摘　　要：为确定安徽省淮北地区不同夏玉米品种的产量性状和适应性,选择安隆4号、鲁单981、中科11号和蠡玉16号为试材,以郑单958为对照,在安徽省淮北地区的太和、颍上、宿州和蒙城等4个地区进行了种植试验,比较其增产潜力和生态适应性。结果表明:4个试点玉米平均产量由高至低的顺序为太和试点,宿州试点,颍上试点,蒙城试点。同一品种在4个试点间的稳产性由好至差的顺序为郑单958,蠡玉16号,中科11号,安隆4号,鲁单981。同一试点不同品种间产量差异显著。太和、颍上、宿州和蒙城试点分别以安隆4号、蠡玉16号、鲁单981和安隆4号产量最高。品种特性和4个试点光照、降水量的不同是造成产量差异的重要原因。通过选用合理玉米品种以充分利用生态资源,发挥区域优势,可实现安徽省夏玉米高产稳产。The objective was to research the yield potential and adaptability in Huaibei area. Four different summer maize varieties, Anlong 4, Ludan 981, Zhongke 11 and Liyu 16 and the control varity-- Zhengdan 958 were planted in four different ecological areas of Taihe, Yingshang, Suzhou and Mengcheng in this experiment. The results showed that the order of the average grain yield from high to low was Taihe, Suzhou, Yingshang and Mengcheng while the order of the variety stability of the same variety in four areas from good to poor was Zhengdan 958, Liyu 16,Zhongke 11, Anlong 4 and Ludan 981. The yield difference among the varieties was significant in the same area. The highest yield varieties in Taihe, Yingshang, Suzhou and Mengcheng were Anlong 4, Liyu 16, Ludan 981 and Zhongyu 15 respectively. Important reasons for the yield difference in these four areas were rarity characteristics,differences in illumination and rainfall. This showed that high grain yield of maize in Anhui province can be obtained by planting different cultivars,making good use of its ecological resources,and by exploiting regional advantages.
