摘要
为了持续推进寒旱区冬小麦品种选育与应用,以陇鉴系列冬小麦品种为例,回顾和讨论了陇东地区冬小麦育种目标、基因背景来源、主要方法措施、品种改良进展和推广应用情况。提出今后的冬小麦育种工作应以抗旱优质为主,兼顾抗条锈病、白粉病等的育种目标,采用辅助选择和多生态鉴定方法相结合的后代选择方法,保持抗寒抗旱和抗条锈病的优势,同时要加强矮秆丰产品种、抗白粉病品种的筛选,加快寒旱区优质小麦推广应用。
In order to continuously promote the breeding and application of winter wheat varieties in cold and arid areas,taking the Longjian series of winter wheat varieties as an example,the breeding goals,genetic background sources,main methods and measures,progress in variety improvement and promotion and application of winter wheat in the Longdong area were reviewed and discussed.It was proposed that the future winter wheat breeding work should focus on drought resistance and high quality,while taking into account of the breeding goals such as resistance to stripe rust and powdery mildew.The progeny selection method combining assisted selection and multi-ecological identification methods should be used to maintain the advantages of cold resistance,drought resistance and resistance to stripe rust.At the same time,the screening of short-stalked high-yield varieties and powdery mildew-resistant varieties should be strengthened to accelerate the promotion and application of high-quality wheat in cold and arid areas.
