在1954年美国的 Stephens J.C.育出第一个细胞质雄性不育系 CK60A 以后,高粱杂种优势才得以广泛开展利用。近30年来,杂交高粱的应用使世界高粱的生产迅速发展。生产实践也证明,杂交高粱较纯系品种增产20～40%,表现强的杂种优势,这无疑有其生理生化代谢基础。国内外一些学者对杂交高粱干物质生产与分配、酶学特性乃至亚细胞水平上的研究等已有诸多报道。本文仅就其有关高粱杂种优势的部分缕述如下,为高粱育种者提供参考。 After the first cytoplasmic male sterility line CK60A was raised by Stephens J.C. in the United States in 1954, the sorghum heterosis was widely used. In the past 30 years, the application of hybrid sorghum has made the world’s sorghum production develop rapidly. Production practice also proves that hybrid sorghum 20% to 40% more yield than the pure lines, showing strong heterosis, which undoubtedly has its physiological and biochemical metabolic basis. Some scholars at home and abroad have reported many reports on the production and distribution of dry matter in sorghum, the enzymatic properties and the subcellular level. This article only on the part of its sorghum heterosis is described below, provide a reference for sorghum breeders.
