- 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.
