杂草稻研究进展

The Research Advanceson Weedy Rice

杂草稻是一类具有杂草特性的自生稻株,对水稻生产的影响越来越严重。但杂草稻长期处于野生状态中,经受各种灾害和不良环境的选择,对环境的适应性较强,存在许多优异性状基因资源。为了进一步了解和利用杂草稻,从性状特征、分类、起源、分布、危害与防治、优异基因挖掘等方面对杂草稻的国内外研究现状进行了综述,指出了加强中国对杂草稻的有益基因挖掘研究具有重要意义。

Weedy rice is a kind of plant self-generated in rice field with weedy character and influenced common rice production greatly. But the weedy rice has been living in natural conditions for long and suffered from all adverse environments, so it would have good ability to adapt to environments and many elite trait genes. In order to further understand and utilize this kind of plant, in this paper, the research advances on weedy rice were summarized in characters, classification, origin, distribution, control of damage, and the elite genes exploitation, and suggested that there were great significances to strength exploitation of weedy rice. en research on gene
