Abstract: 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.

Key words: breeding, germplasm resources, pasture-livestock industry, silage, sweet sorghum
