摘要： 为适应南充市及西南地区春玉米生产发展需要，筛选适合该地区种植的新杂交玉米组合，采用田间调查、室内考种、单收单打、随机区组设计和统计分析等方法，开展了乐禾企业联合体西南春玉米区域试验。结果表明，综合农艺和经济性状且抗病性较好的品种有良农1号，比渝单8号（CK）增产18.2%，达显著水平，正昊235，比渝单8号（CK）8.0%。可以作为南充和西南地区春玉米适宜品种进行示范推广，是南充市国家现代农业示范区和国家科技园区比较理想的高产、优质、抗逆性强、抗病性较好的新品种。

Abstract: To meet the needs of spring corn production and development, and select new hybrid corn combinations which are suitable for planting in Nanchong and southwest China, a regional experimental study on spring corn varieties in southwest China developed by Le He Enterprise Combination was conducted. The methods of field investigation, laboratory test, single collection, randomized block design and statistical analysis were used in the experiment. The results showed that‘Liangnong No.1’ and ‘Zhenghao235’ were better than CK in agronomic characters, economic characters and disease resistance. The yield of‘Liangnong No.1’was significantly higher than that of‘Yudan No.8’(CK) by 18.2%, while the yield of‘Zhenghao235’ increased by 8.0% compared with that of‘Yudan No.8’.‘Liangnong No.1’and‘Zhenghao235 ’could be used as the suitable varieties for demonstration in Nanchong and southwest China, with the advantage of high-yield, high-quality, strong stress resistance and disease-resistance. They could also be used as the ideal varieties in Nanchong National Modern Agricultural Demonstration Zone and National Agricultural Science and Technology Park.
