摘要：

药用野生稻具有丰富的遗传多样性并含有大量优异基因。对药用野生稻的利用主要存在遗传学背景不清楚、常规育种效率不高两方面的障碍。这些问题可以通过构建药用野生稻可转化大片段基因组文库和转基因技术，将大片段克隆导入栽培稻中，建立全基因组基因嵌入突变体库来解决。本文对国内外药用野生稻有利基因发掘及其利用的研究进展进行综述。

Abstract:

Oryza officinalis Wall accumulated abundant genetic diversity and contains a large number of important beneficial genes. The indistinct molecular genetics background of Oryza officinalis Wall and the low efficiency of conventional breeding were two obstacles on the utilization of Oryza officinalis Wall. By using transgenic technology to transfer large fragment to cultivated rice to buiding gene insertion mutant libraries and transformation-competent large fragment libraries of wild rice, these problem were resolved. In this paper the auther summaried the research of excellent genes in Oryza officinalis Wall and utilization of those genes
