Objectives Silage maize varieties with high-quality and high-yield and suitable for promotion and cultivation in the Tongliao region, Inner Mongolia, were selected. Methods 22 silage maize varieties were selected to conduct the experiment with a randomized block design in the field of the Tongliao Institute of Agricultural and Animal Husbandry Sciences, Inner Mongolia. A comprehensive and comparative analysis was conducted on the growth period, the stress resistance including lodging rate, nodule smut, and leaf spot disease, the biological yield including fresh grass yield, dry grass yield, and kernel yield, the agronomic traits including plant height, stem diameter, number of green leaves, number of withered leaves, and number of effective panicles ears, and the nutritional quality including starch, crude protein, neutral detergent fiber, and acidic detergent fiber of different silage maize varieties. Results Different varieties had different growth periods, ranging from 98 days to 122 days. The strongest resistance to lodging inversion was in Mengqingsilage 17272, with a lodging inversion rate of 0.14%. The lowest incidence of nodule smut was in Xianyu 1611 and Jingke 968, with a disease rate of 0. The highest dry matter yield was in Xianyu 1710, being 1 487.44 kg/667 m². The content of dry matter in Xianyu 1620, Xianyu 1611, Jinling Silage 377 and Xianyu 1710 all reached more than 30%, and the content of starch in them was higher as well, reaching more than 35%, but the content of neutral detergent fiber and acid detergent fiber in them was lower. There was not much difference in the content of crude protein among different varieties, with Beinong silage 368 having the highest content at 10.03%. Conclusions The Xianyu series including 1710, 1620, 1611, the Jinling silage series including 377, 97, the Mongolian silage including 17272, 266, Jingjiu silage 16, and Jingke 968 meet the requirements of yield, quality, and adaptability for silage maize planted in the Tongliao region, and are suitable for large-scale promotion and planting in this region.
