杂草稻研究进展

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。

The Research Advances on Weedy Rice

weedy rice is a kind of plants self-generated in rice field with weedy character. These plants influenced greatly on common rice production. But, the weedy rice always lived in natural conditions and suffered from all of adverse environments, so they would have good ability to adopt environments and there may be many elite trait genes in them. In this paper, the research advances on weedy rice were summarized in characters, classification, origin, distribution, control of damage, and the elite genes mining.
