Abstract: To provide a basis for the validation of new corn varieties, promote the development of corn production in Nanchong and Sichuan, and select the new hybridized corn variety combinations which are suitable for planting in this area, the corn varieties regional test in gentle hilly area was conducted in Nanchong, the methods of field investigation, laboratory test, single collection, randomized block design and statistical analysis were used. The results indicated that‘SAU1516’,‘Xinyu 822’,‘ CN3368’,‘ YA3922’, ‘GD14016’and‘HF3368’had better performance in agronomic and economic characters and disease resistance, the yield of those varieties were significantly higher than that of‘Chengdan 30’(CK) by 8.4%, 7.9%, 7.1%, 6.9%, 6.7% and 6.1%, respectively. These varieties could be used as the reference for the varieties validation in Nachong by Sichuan Crop Varieties Examination and Approval Committee and used as the new cultivars for demonstration in Sichuan and Nanchong. With the advantage of high-yield, high-quality, strong stress resistance and disease- resistance, they were ideal varieties in Nanchong National Modern Agricultural Demonstration Zone and National Agricultural Science and Technology Park.
