Abstract To screen high and stable yield maize varieties suitable for Mengcheng County, growth period, agronomic characteristics, stress resistance and yield indices of 22 maize varieties including Quanke 785 were determined using random sampling method, in accordance with NY/T 1209—2020 Code of Practice for Crop Variety Test and Information Technology – Maize. The results showed that, compared with the control variety Xindan 58 (CK), Denghai 1976 and Yueliang 660 had longer growth periods, while Jingnongke 458 had a shorter growth period. Plant height of each variety ranged from 204 to 274 cm. Among which, Jingnongke 458, Ganyu 331, Xinrui 25 and Jinghua 830 exhibited moderate plant heights ranging from 230 to 260 cm. The grain yields of Jingnongke 458, Longding 728, Xinrui 25, Ludan 510, Hanyu 919, Xindan 58, Jinghua 830 and Yueliang 660 were higher than 85%. Kangnongyu 8009 showed severe lodging. Among all tested varieties, Jingnongke 458 had the highest yield (478.8 kg/667 m²), whereas Ludan 510 had the lowest yield (301.4 kg/667 m²). Comprehensive evaluation indicated that a total of 6 varieties, namely Jingnongke 458, Jinghua 830, Yueliang 660, Xinrui 25, Ganyu 331 and Zhongbo 919, performed well comprehensively and could be popularized according to the actual production conditions in the study area.
