摘　　要：青稞作为西藏地区人们的主要粮食作物,其育种进程较长。为了加快其进程,在与西藏气候相当的云南元谋进行了6年的南繁加代技术实践,形成一套完备的适合青稞加代繁殖的技术。同时,总结该技术在选地、播种、田间管理和病虫害防治方面的经验,也指出南繁加代技术对促进缩短青稞育种年限和加速繁殖品种的重要意义。As the leading crop in Tibet, highland barley has a long breeding period. To accelerate the process, the technology of off-seasonmultiplications add generation was applied into practice for six years in Yuarimou, Yunnan province, whose climate is similar to Tibet. Final-ly, a complete set of technology of off-season multiplication add generation for highland barley was achieved. The technologies in choosingland, sowing, managing the field and preventing the pests and diseases were Summarized. What＇ s more, the significance of the technology ofoff-season multiplication add generation on shorting the breeding period of highland barley and accelerating the reproduction varieties was pro-posed.
