高梁是重要的旱粮作物,它具有多重抗逆性、高光合效应、强大的杂种优势和多种用途。在世界谷物生产中继小麦、水稻、玉米之后占第四位(Doggett,1970;Webster,1973)。特别是在非洲大陆,由于连年干旱饥荒,以抗旱著称的高梁更受重视,被誉为“救命的谷物”。目前高梁生产应用杂交种占绝对优势,而杂交种所用的细胞质雄性不育系几乎全部依赖
Sorghum is an important upland grain crop with multiple stresses, photosynthetic effects, powerful heterosis and multiple uses. Fourth in the world after wheat, rice, and corn are cereal production (Doggett, 1970; Webster, 1973). Especially on the African continent, due to years of drought and famine, sorghum known for its resistance to drought has been given more prominence as the “life-saving cereal.” Currently sorghum production and application of hybrids occupy an absolute advantage, and hybrids used in cytoplasmic male sterile lines almost entirely dependent
