摘　　要：为了加速国审玉米新品种榆单808的推广应用,该试验介绍了榆单808的亲本来源、特征特性及栽培制种技术要点。榆单808是陕西大地种业(集团)有限公司以母本Y9329和父本Y4001杂交组配选育而成的玉米新组合,2021年分别通过陕西省关中夏播玉米区审定(陕审玉20210060号)和国家黄淮海夏玉米区审定(国审玉20210497),生产试验平均产量达9798.0 kg/hm^(2),比对照增产4.4%。榆单808在黄淮海区域种植时,需根据不同地区9月中旬的气温差异,灵活调整播种时间,同时采取适当密植、及时追肥保证高产。To accelerate the dissemination and application of‘Yudan 808’,a newly approved maize variety,this study provides a comprehensive overview of its parental lineage,distinguishing characteristics,and key techniques for cultivation and seed production.Developed by Shaanxi Dadi Seed Group Co.,Ltd,‘Yudan 808’is a maize hybrid derived from the crossbreeding of the female parent Y9329 and the male parent Y4001.In 2021,it received approval for cultivation in the Guanzhong summer maize region of Shaanxi Province(Approval No.Shanshenyu 20210060)and the national Huang-Huai-Hai summer maize region(Approval No.Guoshenyu 20210497).Production trials demonstrated an average yield of 9798.0 kg/hm^(2),representing a 4.4%increase over the control variety.For optimal performance in the Huang-Huai-Hai region,sowing times should be adjusted flexibly based on regional temperature variations around mid-September.Additionally,adopting strategies such as appropriate dense planting and timely topdressing is critical to achieving high yields.
