| 摘 要： | 甜高粱是最有应用前景的再生能源作物之一,它的能源转换效率取决于植株总生物量和茎秆汁液含糖量的高低。探明决定甜高粱总生物量和茎秆汁液含糖量积累相关过程的生物学机制并开发相应分子标记,是选育生物能专用甜高粱品种的有效途径。该文从甜高粱糖分积累、遗传多样性研究、遗传图谱的构建、含糖量相关性状的定位及遗传工程研究等方面介绍了近年来甜高粱遗传研究进展。

| Abstract: | Sweet sorghum(Sorghum bicolor L.Moench)is considered one of most potentially valuable sources for biofuel production.Total biomass and sugar content of stem extracts determine the energy conversion efficiency in sweet sorghum.The effective approach to develop elite sweet sorghum with superior biomass and high sugar content is to understand the molecular mechanism and identify the molecular markers that genetically associated with the traits and the genes.Main research progress achievements of genetic improvement in sweet sorghum are highlighted,including of the investigation of stem sugar accumulation,assessment of genetic diversity,construction of genetic maps and identification of QTLs for sugar-related traits in this brief review. |
