The Agricultural Science Institute of Tibet Autonomous Region advocated the collaboration of Aoki breeding in the Qinghai-Tibet Plateau and investigated the history, current status and problems of the breeding of Aoki in various provinces (districts) in the region by means of communication and field visits.
