Abstract: 【Objective】 The purpose of this study is to screen out high-quality silage corn varieties suitable for planting in Xinjiang. 【Methods】 17 silage corn varieties (silage-specific, grain-feeding, ordinary) were selected as research objects to carry out variety comparison tests, and analyze the differences in yield, agronomic characters and nutritional quality of the tested varieties. 【Results】 The results showed that the growth days of Xinsiyu 13 was the shortest (116 d) and Guisilage 1 was the longest(143 d).The hay yield of Enxiai 298 was the highest (70.33 t/hm²) and Xinyu 15 was the lowest (25.69 t/hm²).The grain yield of Xinwo 1 was the highest (10.75 t/hm²) and Tunyu 168 was the lowest (5.95 t/hm²).Among the agronomic characters, the plant height of Aoyu 5102 was the highest (359 cm) and Xinyu 15 was the lowest (241.67 cm).The ear height of Guisilage 1 was the highest (224.67 cm) and Heyu 187 was the lowest (97.67 cm).The lodging rate of Xinsiyu 13 was the highest (36.98%), Xianyu 335, Zhengdan 958, Xianyu 1321, Xinyin KWS2564, Xinyu 15, Jingke 968 and Xiannuoyu 335 did not lodge.The fold rate of Guisilage 1 was the highest (9.73%), Xinsiyu 13, Xinyin KWS2564, Xinyu 15, Xianyu 1321, Zhengdan 958, Tieyan 53 and Tunyu 168 did not fold.In nutrition, Xinwo 1 was the highest (38.83%) and Heyu 187 was the lowest (24.16%).The Starch content of Xianyu 335 was the highest (32.77%) and Heyu 187 was the lowest (23.75%).The crude protein (CP) content of Jingke 968 was the highest (9.00%) and Xinyu 15 was the lowest (7.47%).The Water-soluble carbohydrate (WSC) content of Xiannuoyu 335 has the highest (41.28%)and Aoyu 5102 has the lowest(13.24%).The Neutral washing fiber (NDF) of Zhengdan 958 was the lowest (43.93%) and Xinsiyu 11 was the highest (55.97%).The acid washing fiber (ADF) of Jingke 968 was the lowest (24.96%) and Aoyu 5102 was the highest (40.56%).The comprehensive value rank was, Xianyu 335>Xianyu 1321>Enxiai 298>Jingke 968>Xinsiyu 13>Xiannuoyu 335>Xinwo 1>Zhengdan 958>Xinsiyu 12>Xinsiyu 11>Tieyan 53>Xinyin KWS2564>Guisilage 1>Tunyu 168>Heyu 187>Xinyu 15>Aoyu 5102. 【Conclusion】 Based on the comprehensive analysis of yield and quality, Xianyu 335, Xianyu 1321 and Enxiai 298 were suitable to be popularized and planted as silage corn varieties in Xinjiang.
