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.
