Abstract: To screen for high-yield and high-quality silage corn (Zea mays) varieties suitable for growth in Tongliao, Inner Mongolia, this study conducted an introduction trial with 19 maize varieties of different types, including grain-forage dual-purpose, silage-specific, sweet, and waxy corn. Comprehensive analyses were performed on their agronomic traits, yield traits, and quality traits. The experimental results showed that ‘Zhongyu 335’ had the highest fresh biomass yield (78.82 t?hm-2) and optimal agronomic traits such as plant height and number of green leaves. ‘DK815’ demonstrated remarkable performance in dry forage yield (24.84 t?hm-2) and fiber content. ‘Yuhe No.2’ exhibited high stability in agronomic traits and yield. Grey relational analysis indicated that ‘Zhongyu 335’ ‘DK815’ and ‘Yuhe No.2’ had the highest degree of consistency with the “ideal variety” in comprehensive traits. Correlation analysis revealed that fresh biomass yield was significantly positively correlated with plant height, ear height, and number of green leaves, while starch content was significantly negatively correlated with fiber and crude protein contents.Therefore, the grain-forage dual-purpose varieties ‘Zhongyu 335’ ‘DK815’ and ‘Yuhe No.2’ are suitable for promotion and cultivation in the Tongliao region. This has important implications for optimizing the forage supply structure, improving livestock production benefits, and promoting the sustainable development of agriculture in the region.

摘要: 为筛选适应内蒙古通辽地区生长的高产优质青贮玉米(Zea mays)品种,本研究选取粮饲兼用型、青贮专用型、甜玉米和糯玉米等不同类型的19 个玉米品种进行引种试验,对其农艺性状、产量性状和品质性状进行综合分析。试验结果表明,‘中玉335’鲜草产量最高(78.82 t·hm-2),且株高、绿叶数等农艺性状最优;‘DK815’的干草产量达24.84 t·hm-2且纤维含量表现突出;‘雨禾2号’农艺性状与产量稳定性较高。灰色关联分析显示,‘中玉335’‘DK815’和‘雨禾2号’综合性状与“理想品种”契合度最高。相关性分析表明,鲜草产量与株高、穗位高、绿叶数呈极显著正相关关系,淀粉含量则与纤维及粗蛋白含量呈极显著负相关关系。 因此,粮饲兼用型‘中玉335’‘DK815’和‘雨禾2号’适宜在通辽地区推广种植。这些品种的推广对优化本地区饲草供应结构、提升养殖业效益以及推动农业可持续发展等都具有重要意义。
