Abstract: The 40 summer maize varieties passing the certification were selected, variety comparison field trials were carried out at Xunxian located in northern Henan, Xuchang located in central Henan, and Fangcheng located in southern Henan. The high-yield and high-efficiency comprehensive evaluation index of summer maize varieties was constructed to carry out a comprehensive evaluation of the adaptability of summer maize varieties in three ecological regions from aspects of high and stable yield and climate resource utilization efficiency. The results show that the full growth period length of summer maize varieties was shortest at Fangcheng, with an average value of 108 days, and it was longest at Xunxian, with an average value of 111 days. The difference of the full growth period length of summer maize varieties ranged from 12 to 16 days in three ecological regions, and the full growth period length was correlated significantly with the flowering and grain period. The average yield of summer maize varieties at Fancheng was highest, while it was lowest at Xuchang, and yield difference between two ecological regions passed the 0.05 significance test. The highest utilization rates of light, temperature, water were at Fangcheng. The light and temperature utilization rate was higher at Xunxian than at Xuchang, but the water use efficiency was lowest at Xunxian. According to the ranking of high-yield and high-efficiency evaluation comprehensive index of summer maize varieties, 11 high-yield and high-efficiency summer maize varieties were selected including Weike 702, Qingyu 9, Xindan 68, Denghai 605, Dafeng 30, Zhengdan 1002, Fengdecunyu 10, Jundan 29, Zhengdan 538, Huaichuan 39 and SK1098.

摘要: 选择已通过审定的40个夏玉米品种,于2018年在豫北生态区浚县、豫中生态区许昌和豫南生态区方城开展品种比较田间试验,从丰产性、稳产性和气候资源利用率3个角度构建高产高效综合评价指数,对3个生态区品种适应性进行综合评价。结果表明:全生育期长度方城最短,各品种平均值为108 d,浚县最长,各品种平均值为111 d,3个生态区品种间全生育期长度相差12~16 d,且全生育期长度与花粒期长度相关性最强。各品种在方城的平均产量最高,许昌最低,且产量差异通过0.05显著性检验。方城的光温水气候资源利用率均最高,浚县的光、温利用率高于许昌,但浚县水分利用率最低。3个生态区筛选出中伟科702、庆玉9号、新单68、登海605、大丰30、郑单1002、丰德存玉10、浚单29、郑单538、怀川39和SK1098共11个高产高效夏玉米品种。
