Abstract To screen high yield and resistance maize varieties suitable for planting in the northern coastal hilly regions， a safety evaluation and screening comparison test of 18 maize varieties including Dika 517， NK718， and Jinlai 318 was conducted in Qingdao West Coast New Area， Shandong Province from 2021 to 2023， and their agronomic traits （growth period， plant type， plant height， ear height， lodging resistance and barren stalk rate）， disease occurrence and yield were investigated and recorded; the results showed that in terms of agronomic traits， Dika 517 had the shortest growth period， while Dongdan 1331 had the longest; the plant height of each variety ranged from 225 to 330 cm; except for Shihai 836， YF3240， Ainong 001 and Shengrui 688 which were semi-compact type， the other varieties were compact type; most varieties had no lodging or stem breakage; in terms of disease occurrence， the disease grades of leaf spot and rust of Dongdan 1331 were grade 3 and grade 5， respectively， and no smut or stem diseases were found; the disease grades of leaf spot and rust of Denghai 652 were both grade 3， and no smut or rough dwarf disease were found; in terms of yield， Shengrui 688 had the highest yield （8 728.50 kg/hm²）， followed by Dongdan 1331 and Denghai 652 with good yield performance. Comprehensive analysis showed that Dongdan 1331 and Denghai 652 exhibited excellent comprehensive performance in stress resistance and high yield， making them suitable for popularization and cultivation in the local area.
