甜高粱育种应重视的几个问题

Several issues to be stressed in sweet sorghum breeding

能源是现代社会发展的基础,使用化石能源所排放的SO2和CO2已严重威胁到人类生存的环境,而且其资源量日益枯竭。生物质能源具有可再生、低污染、CO2零排放等优点。可用于开发生物质能源的作物很多,其中甜高粱是最有竞争力的能源作物,因此受到广泛关注。目前甜高粱的育种研究还存在许多须要解决的问题,如倒伏、含糖量低、耐贮性差、种质资源贫乏等,文章对这些问题进行了讨论。

Energy is the,basis for the development of modem society, emissions of SO2 and CO2 from fossil fuels have been a serious threat to the global environment, also it is becoming depleted; biomass energy has the advantages of renewable, low-pollution, zero emissions of carbon dioxide and etc. Many crops can be used as biomass energy, and sweet sorghum is the most competitive energy crop, it received extensive attention. Currently, many issues on sweet sorghum breeding still exist, such as lodging, low sugar content, poor storability, mechanized production, and resource shortage. These issues were discussed in this paper.
