摘　　要：【目的】为全面了解宁夏引黄灌区早熟冬小麦冬育5号的早熟性、稳产性及品质概况。【方法】根据2016—2018年宁夏灌区冬小麦区域试验及大面积生产试验数据,采用变异系数度量稳定性的分析方法,结合品种成熟期、农艺性状表现、产量及品质分析,对冬育5号进行综合分析比较。【结果】冬育5号在宁夏引黄灌区成熟期为6月17—19日,较对照早熟5~6 d;株高适中、抗倒伏,锈病和白粉病发生轻,黑胚粒少,群体结构合理、稳产性好;外观商品性好,粗蛋白、湿面筋、吸水率、稳定时间、硬度指数达到国际优质中筋小麦范畴。【结论】冬育5号适宜在宁夏引黄灌区种植,是“一年两熟”制前茬种植较优作物品种(系),具有广阔的推广应用前景。[Object]In order to understand the early maturity,stable yield and quality of early-maturing winter wheat"Dongyu No.5"in Ningxia Yellow River irrigation area.[Method]According to the regional experiment and production experiment in Ningxia Irrigation area from 2016 to 2018,using coefficient of variation to measure stability,and the maturity,agronomic characters,yield and quality of the variety were analyzed.[Result]Maturation of"Dongyu No.5"was June 17 to June 19(5~6 days earlier than CK).The plant height was moderate,the resistance to lodging,the rust and powdery mildew was light,the number of black embryos was small,the population structure was reasonable,and the yield was stable.The appearance was good,crude protein,wet gluten,water absorption,stable time and hardness index reach the international category of high quality medium gluten wheat,which is suitable for planting in Ningxia Irrigation area.[Conclusion]"Dongyu No.5"is the superior variety,as well as the first crop with"two cropping per year"system,and has broad prospect of popularization.
