摘　　要：甜高粱(Sorghum bicolor)具有耐盐碱、高生物量和高光合性能等特性,茎秆富含汁液和糖分,是一种发展潜力巨大的青贮饲草作物。深入解析甜高粱饲用和耐逆性状形成的分子基础,改良和培育饲用甜高粱新品种对我国草牧业发展具有重要意义。该文总结了我国甜高粱基础研究和育种工作进展,并分析了目前存在的问题,为未来育种提供了对策,旨在推动我国饲用甜高粱产业发展,保障大粮食安全。Sorghum bicolor has the characteristics of salinity tolerance, high biomass and high photosynthetic performance. The stem accumulates high amounts of juice and sugar, making it an important silage crop with development potential. In-depth analysis of the molecular basis underlying the formation of S. bicolor forage traits and stress tolerance traits, as well as improvement and breeding of S. bicolor new varieties for forage are of great significance to the development of pasture-livestock industry in China. This review summarizes the research and breeding progress of S. bicolor,analyzes the existing problems, and puts forward countermeasures for S. bicolor molecular breeding in the future, aiming to promote the development of forage S. bicolor industry and ensure the food security in our country.
