Abstract: The study aimed to screen the silage maize varieties suitable for local phenological conditions in Wuyuan County of Inner Mongolia. A screening test was conducted with 10 silage maize varieties introduced in Wuyuan County, including ′Jinling No.37′, ′Jinling No.17′, ′Jinling No.67′, ′Jinling No.10′, ′Wenyu No. 3′, ′Jinyi No.418′, ′Jinyi No.14′, ′Jinyi No.13′, ′Jinyi No.12′ and ′Jinyi No.1157′. The morphology and yield indicators of different silage maize varieties were compared. The results showed that the highest whole plant fresh weight yield was observed in the variety of ′Jinyi No.13′, which was as high as 105 276 kg/hm². It can be concluded that the best silage maize variety suitable for planting in Wuyuan County is ′Jinyi No.13′.
