摘　　要：【目的】筛选出适合在滇东北地区推广种植的青贮新品种。【方法】以当地主推品种雅玉04889为对照种,按照云南省区域试验及公开发表文献所提供的数据采集方法,在2018年对比了曲辰30号、曲辰31号、曲辰32号、曲辰33号、曲辰34号、曲辰35号几个青贮玉米品种的产量和抗病性,在2019年继续对比雅玉04889、曲辰31号、曲辰32号和曲辰33号几个青贮玉米品种的产量和抗病性,并对数据进行分析。【结果】所有品种中仅有曲辰32号是紧凑型。2018年,干物质产量最高的为曲辰32号,后面依次是曲辰33号、曲辰34号、曲辰31号、曲辰30号、曲辰35号;2019年,曲辰32号的干物质产量依然最高。2018年,雅玉04889对灰斑病的抗性最差;2019年,所有品种的抗病性一致。【结论】综合考虑农艺性性状、抗病性和产量,曲辰32号最适合作为青贮玉米在滇东北地区进行栽培。【Objective】Corn silage,known for itshigh feeding value,isan important feed crop.This study aims to select new silage maize varieties suitable for popularization and planting in northeast Yunnan.【Method】Using YY 04889 as the control variety,this study compared the yield and disease resistance of several silage maize varieties,in-cluding YY04889(CK),QC30,QC31,QC 32,QC 33,QC 34 and QC 35,in 2018.Data collection methods were based on regional trials and published literaturefromYunnan Province.In 2019,the comparison was continued with YY 04889,QC31,QC32 and QC 33 to analyze yield and disease resistance further.【Result】The study found that QC 32 demonstratedcompact growth among all varieties.In 2018,QC 32 had the highest dry matter yield,followed by QC 33,QC 34,QC 31,QC30 and QC 35.QC 32 maintained the highest dry matter yield in 2019.In the first year,YY 04889 showedthe poorestresistance to gray spot disease,whilein the following year,the resistance of all varieties was consistent.【Conclusion】Considering agronomic traits,disease resistance and yield,QC 32 is the most suitable for silage cultivation in northeast Yunnan.
