从种质基础比较狭窄、新品种选育缓慢和青贮玉米应用不足等方面,阐述新疆玉米育种中存在的问题,并从丰富玉米种质资源、把握玉米育种方向、注重生物技术应用和完善栽培技术体系等方面,分析新疆玉米育种问题的解决措施,以期为推动新疆玉米生产提供参考。新疆地处我国西北腹地,光热资源非常丰富,昼夜温差较大,在玉米种植与生产方面有着得天独厚的优势。因此,分析新疆玉米育种中存在的问题及对策,对提高新疆玉米产量,推动新疆农业生产发展有着积极的意义。
From the aspects of the narrow germplasm base, the slow breeding of new varieties and the lack of application of silage corn, the problems in breeding of maize in Xinjiang were expounded. From the aspects of enriching maize germplasm resources, grasping the direction of maize breeding, paying attention to the application of biotechnology and improving the cultivation techniques System and other aspects, analysis of Xinjiang maize breeding solution to the problem, with a view to promoting Xinjiang’s maize production to provide a reference. Xinjiang is located in the hinterland of China’s northwest, light and heat resources are very rich, large temperature difference between day and night, planting and production of corn has a unique advantage. Therefore, the analysis of the problems and countermeasures in Xinjiang maize breeding has positive significance to improve the yield of Xinjiang maize and promote the agricultural production in Xinjiang.
